Explain. 2 Could a fibrous joint perform its functions if it were a diarthrosis? Explain your reasoning. Which class of synovial joint do you think would be the most stable? Which class would be the least stable? Explain your choices. 3 4 In the condition synovitis the synovial membrane secretes excess synovial fluid. How might this affect the function of a synovial joint? Articulations UNIT 9251

Answer the following multiply choice questions don't need to explain?    Synovial joints have several features that distinguish them. Some of these features are a joint space, hyaline cartilage covering the articular surface, and synovial membranes that secrete synovial fluid. What is the function of synovial fluid? A. decrease friction between joint surfaces and provide nourishment to articular cartilage B. temporary fluid that occurs during overuse to limit injury C. increase stability of the joint by filling the joint space D. increase friction to slow and control joint movement   1.

A. anterior (maybe) B. medial C. posterior D. middle 1B. Which…

1. Joints can be classified by structure and by function. How would youstructurally and functionally classify the joint involved in the injury in this case? 2. Name the six distinguishing features that define the structural classification of the joint involved in this injury. 3. The doctors noted that there were no bone fragments in the joint space. What is normally found in this space? 4. Surgeons had to remove a portion of Mrs. Tanner’s acetabular labrum. What is this structure and what function does it supply at this joint? 5. The doctors noted that Mrs. Tanner’s thigh was flexed at the hip, adducted, and medially rotated. Describe what this means in terms ofthe position of her leg. 6. Hip dislocations can be classified as anterior or posterior depending on which direction the head of the femur is facing after it dislocates. Based on the description you provided in question 5, which type of dislocation did Mrs. Tanner suffer? 7. In order to assess the joint as part of Mrs. Tanner’s…
