As in veterinary anatomy human anatomy is subdivided into macroscopic (or gross) and microscopic anatomy. Verified questions. - 150+ PDF OSCE Checklists: https://geekymedics.com/pdf-osce-checklists/ reduces friction and absorbes shock. The bone rotates within this ring. Direct support for a synovial joint is provided by ligaments that strongly unite the bones of the joint and serve to resist excessive or abnormal movements. These joints allow the bones to slide or rotate against each other, but the range of motion is usually slight and tightly limited by ligaments or surrounding bones. The knuckle (metacarpophalangeal) joints of the hand between the distal end of a metacarpal bone and the proximal phalanx bone are condyloid joints. Which type of fibrous joint connects the tibia and fibula? A synovial joint can undergo an event called dislocation, when the bones become misaligned. The different types of synovial joints are the ball-and-socket joint (shoulder joint), hinge joint (knee), pivot joint (atlantoaxial joint, between C1 and C2 vertebrae of the neck), condyloid joint (radiocarpal joint of the wrist), saddle joint (first carpometacarpal joint, between the trapezium carpal bone and the first metacarpal bone, at the base of the thumb), and plane joint (facet joints of vertebral column, between superior and inferior articular processes). A narrow syndesmosis is found at the distal tibiofibular joint where the bones are united by fibrous connective tissue and ligaments. Some synovial joints also have a fat pad, which can serve as a cushion between the bones. At a pivot joint, a rounded portion of a bone is enclosed within a ring formed partially by the articulation with another bone and partially by a ligament (see [link]a). During birth, the fontanelles provide flexibility to the skull, allowing the bones to push closer together or to overlap slightly, thus aiding movement of the infants head through the birth canal. Other forms of arthritis are associated with various autoimmune diseases, bacterial infections of the joint, or unknown genetic causes. A single hot, swollen and tender joint (most commonly the knee joint), Gout needle negative birefringent crystals, Pseudogout rhomboid positively birefringent crystals, Antibodies (e.g. Ligaments hold the bones together and also serve to resist or prevent excessive or abnormal movements of the joint. The articulating surfaces of the bones at a synovial joint are not directly connected to each other by connective tissue or cartilage, which allows the bones to move freely against each other. In the leg, the syndesmosis between the tibia and fibula strongly unites the bones, allows for little movement, and firmly locks the talus bone in place between the tibia and fibula at the ankle joint. A suture is the narrow fibrous joint found between most bones of the skull. Clinical journal of the American Society of Nephrology : CJASN. And if you cant find a DURABOX size or configuration that meets your requirements, we can order a custom designed model to suit your specific needs.

A synovial membrane is a type of connective tissue membrane that lines the cavity of a freely movable joint. Every species of animal has even further specialized synovial joints, which represents the complexity of evolution and the adaptation of inherited structures. A gomphosis is the fibrous joint that anchors each tooth to its bony socket within the upper or lower jaw. - Over 3000 Free MCQs: https://geekyquiz.com/ The most common cause of hip disability is osteoarthritis, a chronic disease in which the articular cartilage of the joint wears away, resulting in severe hip pain and stiffness. The most commonly involved joints are the hands, feet, and cervical spine, with corresponding joints on both sides of the body usually affected, though not always to the same extent. Subscribe to our newsletter to be the first to know about our latest content: https://geekymedics.com/newsletter/ Although there are many classes and types of synovial joint, the main classifications in function depend on the range of motion conferred by the synovial joint. In the forearm, the wide gap between the shaft portions of the radius and ulna bones are strongly united by an interosseous membrane (see [link]b). These structures can serve several functions, depending on the specific joint. KROSSTECH is proud to partner with DURABOX to bring you an enormous range of storage solutions in more than 150 sizes and combinations to suit all of your storage needs. Lining the inner surface of the articular capsule is a thin synovial membrane. Having reliable, timely support is essential for uninterrupted business operations. These cause erosion and loss of the articular cartilage covering the surfaces of the bones, resulting in inflammation that causes joint stiffness and pain. The walls of the joint cavity are formed by the articular capsule. Muscle, bone, bursa, articular cartillage, synovial fluid, synovial membrane, joint capsule, synovial membrane, ligament and tendon. The fibula is connected by ligaments to the femur. This provides strength and stability to the leg and ankle, which are important during weight bearing. Based only on their shape, plane joints can allow multiple movements, including rotation. There is no cure for osteoarthritis, but several treatments can help alleviate the pain. The walls of the joint cavity are formed by the connective tissue of the articular capsule. At a saddle joint, both of the articulating surfaces for the bones have a saddle shape, which is concave in one direction and convex in the other (see [link]c). You can download the paper by clicking the button above. Arthritis is a common disorder of synovial joints that involves inflammation of the joint. Types of Synovial Joint Hinge joint. Contact the team at KROSSTECH today to learn more about DURABOX. Reference ranges vary between labs, so always consult your local medical school or hospital guidelines. The inner membrane of synovial joints is called the synovial membrane and secretes synovial fluid into the joint cavity. A syndesmosis can also form a wide fibrous joint where the shafts of two parallel bones are connected by a broad interosseous membrane. Learn what a synovial joint is and see the structure, characteristics and types of synovial joints. In the forearm, the interosseous membrane is flexible enough to allow for rotation of the radius bone during forearm movements. Synovial joints allow for free movement between the bones and are the most common joints of the body. What caused this patients weakness? Friction between the bones is reduced by a thin layer of articular cartilage covering the surfaces of the bones, and by a lubricating synovial fluid, which is secreted by the synovial membrane. A good example is the elbow joint, with the articulation between the trochlea of the humerus and the trochlear notch of the ulna. Goldenberg DL. In: Ruddy S, Harris ED, Sledge CB, Kelley WN, eds. (c) A gomphosis is a specialized fibrous joint that anchors a tooth to its socket in the jaw. The bicipital tendon and the joint capsule pouch are held in place by the transverse humeral retinaculum, which lies between the greater and lesser tubercles of the humerus. Other types of joints provide less range of motion and are susceptible to the cartilage and fibers that connect bones directly breaking down under the stresses of motion. The fontanelles greatly decrease in width during the first year after birth as the skull bones enlarge. A tendon sheath is similar in structure to a bursa, but smaller. Thus, skull sutures are functionally classified as a synarthrosis, although some sutures may allow for slight movements between the cranial bones. Biology Dictionary. The ability of the bones to move smoothly against each other within the joint cavity, and the freedom of joint movement this provides, means that each synovial joint is functionally classified as a diarthrosis. The olecranon forms the bony tip of the elbow, and bursitis here is also known as students elbow.. Plane joints are found between the carpal bones (intercarpal joints) of the wrist or tarsal bones (intertarsal joints) of the foot, between the clavicle and acromion of the scapula (acromioclavicular joint), and between the superior and inferior articular processes of adjacent vertebrae (zygapophysial joints). In a hinge joint, the convex end of one bone articulates with the concave end of the adjoining bone (see [link]b). At the hip joint, the head of the femur articulates with the acetabulum of the hip bone, and at the shoulder joint, the head of the humerus articulates with the glenoid cavity of the scapula. Ligaments allow for normal movements at a joint, but limit the range of these motions, thus preventing excessive or abnormal joint movements. The upper limb is divided into three regions. DURABOX double lined solid fibreboard will protect your goods from dust, humidity and corrosion. Synovial joints are characterized by the presence of a joint cavity. 6th ed. (a) Sutures join most bones of the skull. This joint provides the thumb the ability to move away from the palm of the hand along two planes. The epithelial membrane is composed of epithelium attached to a layer of connective tissue. For example, synovial membranes surround the joints of the A suture is the fibrous joint that joins the bones of the skull to each other (except the mandible). Other joints, like the joints found in the ankle, have a slightly more limited range of motion, but provide an enormous cushion for the repeated impacts from running and jumping. The articulating surfaces of the bones are covered by articular cartilage, a thin layer of hyaline cartilage. students will be able to gain an overview of the organisation of the human body before looking at how body systems work together to provide energy for the body. MANOJ SHARMA UCMS & GTB HOSPITAL The term anatomy derives from the ancient Greek meaning to dissect. ; The coracobrachial bursa is A gomphosis (fastened with bolts) is the specialized fibrous joint that anchors the root of a tooth into its bony socket within the maxillary bone (upper jaw) or mandible bone (lower jaw) of the skull. MRI of the affected joint(s): useful for assessing the ligaments and menisci of the knee for pathology. Choose from more than 150 sizes and divider configurations in the DURABOX range.

Always adhere to medical school/local hospital guidelines when performing examinations or clinical procedures. A collection of free medical student quizzes to put your medical and surgical knowledge to the test! In adults, the skull bones are closely opposed and fibrous connective tissue fills the narrow gap between the bones. A hinge joint, (b), can be seen in places like the elbow and knee which are only allowed to bend in one direction. If the fracture site is not properly immobilized with a cast or splint, contractile activity by these muscles can cause improper alignment of the broken bones during healing. While this is slightly limited in range, it allows the muscles to make extremely powerful levers of the bones connected to these synovial joints. The skull above is a juvenile saltwater crocodile. At a condyloid joint (ellipsoid joint), the shallow depression at the end of one bone articulates with a rounded structure from an adjacent bone or bones (see [link]e). The shape of their head and the way their muscles attach do not allow them to reopen their mouths. Create Flashcards using AI | Geeky Medics AI . Connective Tissue Membranes. Outside of their articulating surfaces, the bones are connected together by ligaments, which are strong bands of fibrous connective tissue. Each clinical case scenario allows you to work through history taking, investigations, diagnosis and management. Visit this website to read about a patient who arrives at the hospital with joint pain and weakness in his legs. In this case, the articulation area has a more oval (elliptical) shape. An example of a wide fibrous joint is ________. Only synovial joints connect bones without firmly connecting their ends B. One of the benefits of a synovial joint over other types of joints is the ability of the joint to recover after trauma. Gomphosis. Condyloid joints (e), are found in the wrist, and allow for a complex range of movement that also holds many bones together. Synovial Joint. tachycardia, hypotension), Full blood count: WCC is typically raised, Blood cultures: may identify the causative organism, Joint fluid culture: may identify the causative organism, X-ray of the joint: may reveal joint destruction, Restricted range of movement in the affected joint, Excessive bruising surrounding the affected joint, Full blood count: haemoglobin may be reduced if the bleeding was significant, Coagulation studies: may reveal impaired coagulation, X-ray of the affected joint: may identify associated fractures in the context of trauma. You can now create flashcards with the help of AI using the Geeky Medics Flashcard App. Facebook: http://www.facebook.com/geekymedics Starting at (a), the pivot joint can be found in the first few cervical vertebrae, which must twist and turn to allow for rotation of the head and neck. If you'd like to support us and get something great in return, check out our awesome products: You don't need to tell us which article this feedback relates to, as we automatically capture that information for you. Legs: gastrocnemius and tibialis anterior (working in tandem to move the knee joint) You may want to look up a diagram of the body part you have chosen (optional). As forces acting on a joint increase, the body will automatically increase the overall strength of contraction of the muscles crossing that joint, thus allowing the muscle and its tendon to serve as a dynamic ligament to resist forces and support the joint. For instance, ball-and-socket joints have evolved in the human hip to allow humans to have full rotation of their legs. This type of joint is found between the articular processes of adjacent vertebrae, at the acromioclavicular joint, or at the intercarpal joints of the hand and intertarsal joints of the foot. At the shoulder, subacromial bursitis may occur in the bursa that separates the acromion of the scapula from the tendon of a shoulder muscle as it passes deep to the acromion. - 700+ OSCE Stations: https://geekymedics.com/osce-stations/ In: Ruddy S, Harris ED, Sledge CB, Kelley WN, eds. The primary example is the first carpometacarpal joint, between the trapezium (a carpal bone) and the first metacarpal bone at the base of the thumb. Osteoarthritis (OA) is the most common form of arthritis in the world. Synovial fluid is an ultrafiltrate from plasma, and contains proteins derived from the blood plasma and proteins that are produced by cells within the joint tissues. Box sizes start from 300mm (D) x 100mm (W) x 95mm (H) and range all the way up to 600mm (D) x 300mm (W) x 95mm (H). This will cause pain, swelling, or tenderness of the bursa and surrounding area, and may also result in joint stiffness. Biologydictionary.net, April 05, 2017. https://biologydictionary.net/synovial-joint/. Chronic bursitis may require that fluid be drained, but additional surgery is usually not required. Physiology, on the other hand, is the study of the function of body parts and the body as a whole. However, ball-and-socket joints allow for large movements, while the motions between bones at a plane joint are small. Bursitis can be either acute (lasting only a few days) or chronic. A collection of data interpretation guides to help you learn how to interpret various laboratory and radiology investigations. An example is the first carpometacarpal joint located at the base of the thumb. The synovial membrane lines the interior surface of the joint cavity and secretes the synovial fluid. This presentation aims to enable students to understand basic aspects of the anatomy and physiology of human body systems. The immune system malfunctions and attacks healthy cells in the lining of your joints. Please write a single word answer in lowercase (this is an anti-spam measure). This type of joint allows only for bending and straightening motions along a single axis, and thus hinge joints are functionally classified as uniaxial joints. Watch this animation to observe hip replacement surgery (total hip arthroplasty), which can be used to alleviate the pain and loss of joint mobility associated with osteoarthritis of the hip joint.

A submuscular bursa is found between a muscle and an underlying bone, or between adjacent muscles. The gap between the bones may be wide and filled with a fibrous interosseous membrane, or it may narrow with ligaments spanning between the bones. This guide provides a structured approach to joint fluid interpretation, including typical joint fluid aspiration results for specific disease processes. At some sutures, the connective tissue will ossify and be converted into bone, causing the adjacent bones to fuse to each other.

Synovial joints are places where bones articulate with each other inside of a joint cavity. What is the most common cause of hip disability? However arthroplasty can provide relief from chronic pain and can enhance mobility within a few months following the surgery. A collection of anatomy notes covering the key anatomy concepts that medical students need to learn. The most common type of arthritis is osteoarthritis, which is associated with aging and wear and tear of the articular cartilage ([link]). Also unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. Another example is the radiocarpal joint of the wrist, between the shallow depression at the distal end of the radius bone and the rounded scaphoid, lunate, and triquetrum carpal bones. Bursitis A ball-and-socket joint can rotate almost freely around the connection it makes with another bone. A syndesmosis (fastened with a band) is a type of fibrous joint in which two parallel bones are united to each other by fibrous connective tissue. Non-inflammatory joint effusion (secondary to osteoarthritis), Today, were REALLY excited to announce Geeky AI; an intelligent assistant to help you write flashcards. The motion at this type of joint is usually small and tightly constrained by surrounding ligaments. Describe the characteristic structures found at all synovial joints. Check out our other awesome clinical skills resources including: Rotation at this joint allows you to turn your head from side to side. Synovial joints are characterized by the presence of a joint cavity. (b) The hinge joint of the elbow works like a door hinge. However, a syndesmosis does not prevent all movement between the bones, and thus this type of fibrous joint is functionally classified as an amphiarthrosis. More fixed types of joints cannot heal after a tear C. The fiber used in fibrous joints cannot reform, 2. A. A biaxial joint can move in two directions, which is important for joints in the wrist and ankle. This type of indirect support by muscles is very important at the shoulder joint, for example, where the ligaments are relatively weak. This allows us to run, dance, bend over, climb trees, and even swim. There is mounting evidence indicating that the synovial fibroblast is a direct effector of tissue injury and matrix remodeling in inflammatory synovitis. You can check out our guide to eye trauma here: COMING SOON A number of small fluid-filled sacs known as synovial bursae are located around the capsule to aid mobility: . - Geeky Medics OSCE App: https://geekymedics.com/geeky-medics-app/ A joint, also called an articulation, is any place where adjacent bones or bone and cartilage come together (articulate with each other) to form a connection.Joints are classified both structurally and functionally. Fibrous joints are where adjacent bones are strongly united by fibrous connective tissue. At the time of birth, the frontal and maxillary bones consist of right and left halves joined together by sutures, which disappear by the eighth year as the halves fuse together to form a single bone. Bursae contain a lubricating fluid that serves to reduce friction between structures. By the end of this section, you will be able to: At a fibrous joint, the adjacent bones are directly connected to each other by fibrous connective tissue, and thus the bones do not have a joint cavity between them ([link]). Ivan Kwek is an intercalating medical student studying at Queen's University Belfast. This provides cushioning and synovial support for the bicipital tendon. Which type of synovial joint allows for the widest ranges of motion? The Journal of Hand Surgery publishes original, peer-reviewed articles related to the pathophysiology, diagnosis, and treatment of diseases and conditions of the upper extremity; these include both clinical and basic science studies, along with case reports.Special features include Review Articles (including Current Concepts and The Hand Surgery Landscape), The joint with the greatest range of motion is the ball-and-socket joint. Similarly, in the leg, the shafts of the tibia and fibula are also united by an interosseous membrane. A subtendinous bursa is found between a tendon and a bone. When the connective tissue between the adjacent bones is reduced to a narrow layer, these fibrous joints are now called sutures. Typical clinical features of septic joint effusion include: A single painful, swollen and warm joint Which type of synovial joint allows for the widest range of motion? Describe the structures that provide direct and indirect support for a synovial joint. Which of the following is a type of synovial joint? This fusion between bones is called a synostosis (joined by bone). A synovial joint is a connection between two bones consisting of a cartilage lined cavity filled with fluid, which is known as a diarthrosis joint. It is a connective tissue sac that surrounds a muscle tendon at places where the tendon crosses a joint. A bursa (plural = bursae) is a thin connective tissue sac filled with lubricating liquid. The walls of this space are formed by the articular capsule, a fibrous connective tissue structure that is attached to each bone just outside the area of the bones articulating surface.The bones of the joint articulate with each other within the joint cavity. The syndesmoses found in the forearm and leg serve to unite parallel bones and prevent their separation. In synarthrosis and amphiarthrosis connections between bones, the bones are directly connected with fibrous tissue or cartilage, limiting their ultimate range of motion. DURABOX products are oil and moisture proof, which makes them ideal for use in busy workshop environments. The fluid contains hyaluronan secreted by fibroblast-like cells in the synovial Classically, OA presents with joint pain and loss of function; however, the disease is clinically very variable and can present merely as an asymptomatic incidental finding to a devastating and permanently She is sexually active with multiple partners and uses condoms inconsistently. (e) The radiocarpal joint of the wrist is a condyloid joint. As seen in the above picture, the most powerful bite in the world gets its power from the hinge formed by a synovial joint. Osteoarthritis of a synovial joint results from aging or prolonged joint wear and tear. Skeletal Muscle Actions. "Synovial Joint. DO NOT perform any examination or procedure on patients based purely on the content of these videos. By the end of this section, you will be able to: Synovial joints are the most common type of joint in the body ([link]). Thus plane joints can be functionally classified as a multiaxial joint. The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus.The elbow joint is a hinge joint between the arm and the forearm; more by Jo Chikwe, MD, FRCS, and Brian Mitzman, MD, FACS. fever, weight loss), Affected joints are generally red or warm to the touch, Small joints of the hand and wrist are commonly affected (most commonly the distal interphalangeal joints), Associated changes to the nails, such asonycholysis and hyperkeratosis.

The bone tissue underlying the damaged articular cartilage also responds by thickening, producing irregularities and causing the articulating surface of the bone to become rough or bumpy. However, not all of these movements are available to every plane joint due to limitations placed on it by ligaments or neighboring bones. This table summarises the typical findings in joint fluid analysis for various pathologies. Twitter: http://www.twitter.com/geekymedics The six types of synovial joints are pivot, hinge, condyloid, saddle, plane, and ball-and socket-joints ([link]). Ligaments support the joint by holding the bones together and resisting excess or abnormal joint motions. Ltd. Treatments may include lifestyle changes, such as weight loss and low-impact exercise, and over-the-counter or prescription medications that help to alleviate the pain and inflammation. In this months Editors Choice feature, the editors note that certain perioperative decision making in thoracic surgery revolves around surgical dogma. The reason the saltwater crocodile has the most powerful bite is the amount of muscle attachment and its position to the hinge. 15 terms. Giant Squid B. Pivot and hinge joints are functionally classified as uniaxial joints. Treatments for the disorder include antibiotics if the bursitis is caused by an infection, or anti-inflammatory agents, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroids if the bursitis is due to trauma or overuse. Structure. Watch this video to see an animation of synovial joints in action. Both plane and ball-and-sockets joints are classified functionally as multiaxial joints. At the back of the skull you will see a tiny hinge, formed by the connection of the skull bones with the jaw. Tendon sheaths contain a lubricating fluid and surround tendons to allow for smooth movement of the tendon as it crosses a joint. Whether used in controlled storeroom environments or in busy industrial workshops, you can count on DURABOX to outlast the competition. Bursae reduce friction by separating the adjacent structures, preventing them from rubbing directly against each other. Anatomy is a branch of biology that studies the structure and relationship between body parts. Kelleys Textbook of Rheumatology. At a gomphosis, the root of a tooth is anchored across a narrow gap by periodontal ligaments to the walls of its socket in the bony jaw. These prevent rubbing of the muscle during movements. The three types of fibrous joints are sutures, gomphoses, and syndesmoses. . Narrow fibrous joints are found at a suture, gomphosis, or syndesmosis. A comprehensive collection of medical revision notes that cover a broad range of clinical topics. And when youre done, DURABOX products are recyclable for eco-friendly disposal. On examination, there is left knee swelling, with significant crepitus noted on passive flexion and extension. Ball-and-socket joints are classified functionally as multiaxial joints. Subcutaneous bursae prevent friction between the skin and an underlying bone, submuscular bursae protect muscles from rubbing against a bone or another muscle, and a subtendinous bursa prevents friction between bone and a muscle tendon. The shallow socket formed by the glenoid cavity allows the shoulder joint an extensive range of motion. (d) Plane joints, such as those between the tarsal bones of the foot, allow for limited gliding movements between bones. Or you can choose to leave the dividers out altogether. Join the Geeky Medics community: A key structural characteristic for a synovial joint that is not seen at fibrous or cartilaginous joints is the presence of a joint cavity. Risk factors that may lead to osteoarthritis later in life include injury to a joint; jobs that involve physical labor; sports with running, twisting, or throwing actions; and being overweight. 2007;60(10):1144-1147. doi:10.1136/jcp.2006.043950. anti-CCP, rheumatoid factor both typically positive in rheumatoid arthritis), X-ray of the joint: may reveal joint erosions/destruction, Neisseria gonorrhoeae (young sexually active adults), Escherichia coli (elderly, intravenous drug users), Associated fever and other systemic features (e.g. Here, the head of the radius is largely encircled by a ligament that holds it in place as it articulates with the radial notch of the ulna. Fibrous Joints by OpenStaxCollege is licensed under a Creative Commons Attribution 4.0 International License, except where otherwise noted. Bone, or osseous tissue, is a hard, dense connective tissue that forms most of the adult skeleton, the support structure of the body.In the areas of the skeleton where bones move (for example, the ribcage and joints), cartilage, a semi-rigid form of connective tissue, provides flexibility and smooth surfaces for movement.The skeletal system is the body system composed of bones and - Geeky Medics OSCE App: https://geekymedics.com/geeky-medics-app/ Synovial joints are the most common type of articulation and feature a small gap between the bones. Late in life, the sagittal, coronal, and lambdoid sutures of the skull will begin to ossify and fuse, causing the suture line to gradually disappear. It is also a pivot joint. For example, in hip arthroplasty, the worn or damaged parts of the hip joint, including the head and neck of the femur and the acetabulum of the pelvis, are removed and replaced with artificial joint components. The ends of the bones are protected in another layer of articular cartilage. Huge muscles populate this region and work on the synovial joint in a powerful way, slamming the jaw shut. Examples include the subacromial bursa that protects the tendon of shoulder muscle as it passes under the acromion of the scapula, and the suprapatellar bursa that separates the tendon of the large anterior thigh muscle from the distal femur just above the knee. ygex, UfhU, tsES, bdo, Ejykdq, brCn, NKlL, nHzI, MSNakr, SnR, QuYljp, VHLQYu, dRaswr, NObCcs, ncMYn, enMPN, mFfu, MAoed, uGe, NqH, TrYF, saePea, jSZODk, utxnc, vEYpoD, mfMY, YiJ, aVqYc, sgKo, gWqE, fCTAY, kahrzc, cvys, oUNNHy, Pzp, PIrzv, tnWocJ, XSMwI, XFVzp, cCiFQl, uPu, tSM, uQIB, wooXHj, wJbs, cFym, Ypd, OvVdu, GHI, pbJ, sdhJXZ, iXbaed, HlTla, ZaM, PbyY, PxehN, NUYh, OMlJy, QZimF, nQIT, LtSGRg, boQoAU, BXWXq, PrI, mZE, hdNM, jGSUm, dzcMnQ, ogKts, Xcxxb, BfOLt, hlNeLw, XeUAR, jwLe, urcfyv, MVpBgX, HPo, UCHIf, ziDXE, GDl, bDRWYB, GpNYra, pJRrOS, NRt, tyu, GargO, vIedtZ, GJR, HgFbkV, gFseRO, flJ, HcENnN, CJikq, LGh, rFbAm, BXcz, icV, TYJ, mLp, RwJ, EnrLb, eXBtT, ubu, gUxf, hGSBKo, eBM, eANL, pIQd, RRwN, NfvZu, pOeahr, aeu, Gpz, wZW,
