Final answer:
A synovial joint is made up of the synovial membrane, articular capsule, joint cavity with synovial fluid, articular cartilage, and bone ends. The synovial membrane produces synovial fluid, which lubricates the joint. These joints are found in various locations in the body.
Step-by-step explanation:
Synovial Joint Structure:
The structural features of a synovial joint include the synovial membrane, articular capsule, joint cavity with synovial fluid, articular cartilage, and bone ends.
The synovial membrane lines the inner surface of the joint capsule and produces synovial fluid.
The articular cartilage covers the bone ends, providing a smooth surface for movement.
The joint cavity contains synovial fluid, which lubricates the joint and reduces friction.
Main Functions:
The synovial membrane produces synovial fluid, which lubricates the joint and nourishes the articular cartilage.
The articular cartilage reduces friction and absorbs shock during movement.
The joint cavity with synovial fluid allows for smooth movement between the bone ends.
Location:
Synovial joints are found throughout the body, including the knee, elbow, shoulder, hip, and fingers.
