What is the primary function of the synovial membrane in synovial joints?
Solution
Correct Answer: Option A
- The primary function of the synovial membrane in synovial joints is to produce synovial fluid.
- This fluid plays a crucial role in lubricating the joint, thereby reducing friction between the articular cartilage of the bones during movement.
- Additionally, synovial fluid provides nutrients to the avascular articular cartilage and helps in the removal of metabolic waste.
- It is important to note that the synovial membrane does not provide structural support to the joint capsule (Option 2), nor does it manufacture the hyaline cartilage that covers the articular surfaces (Option 3). The hyaline cartilage is produced by chondrocytes within the cartilage itself. Also, the synovial membrane is not a site for ligament attachment (Option 4); ligaments typically attach to bone, not to the synovial membrane.
In summary, the synovial membrane’s essential role is to secrete synovial fluid, ensuring joint mobility and health.
