Verified step by step guidance

Understand the structure of a synovial joint: Synovial joints are freely movable joints characterized by specific components such as the joint capsule, articular cartilage, synovial membrane, and sometimes menisci.

Define the joint capsule: The joint capsule is a tough, fibrous structure that encloses the joint cavity and provides stability to the joint. It is often reinforced by ligaments and tendons to enhance its strength and limit excessive movement.

Explain the role of ligaments and tendons: Ligaments connect bone to bone and provide stability to the joint by reinforcing the joint capsule. Tendons connect muscle to bone and may also contribute to joint stability by supporting the capsule during movement.

Clarify the function of articular cartilage: Articular cartilage covers the ends of bones within the joint, reducing friction and absorbing shock during movement. It is not reinforced by ligaments or tendons.

Discuss the synovial membrane and meniscus: The synovial membrane lines the inner surface of the joint capsule and produces synovial fluid for lubrication. The meniscus, found in some synovial joints, acts as a cushion and stabilizer but is not reinforced by ligaments or tendons.
