Verified step by step guidance

Step 1: Begin by understanding the anatomy of a synovial joint. Synovial joints are the most common type of joint in the body and are characterized by their ability to allow free movement between bones.

Step 2: Identify the key structures of a synovial joint. These include articular cartilage, ligaments, the joint capsule, and the synovial membrane. Each structure has a specific function: articular cartilage reduces friction and absorbs shock, ligaments provide stability, the joint capsule encloses the joint, and the synovial membrane produces synovial fluid for lubrication.

Step 3: Examine the diagram and locate the part labeled 'a'. Determine its position and appearance relative to the other structures in the joint. For example, articular cartilage is typically found covering the ends of bones, while the synovial membrane lines the inner surface of the joint capsule.

Step 4: Match the labeled part 'a' to its corresponding structure based on its anatomical location and function. Use the descriptions of each structure to make an informed decision.

Step 5: Confirm your answer by reviewing the characteristics of the structure you selected and ensuring it aligns with the label 'a' in the diagram. This process helps reinforce your understanding of synovial joint anatomy.
