synovial membrane
Definition
Noun: A thin, soft tissue layer that lines the inner surface of the capsule of a freely moving (synovial) joint. Its primary function is to secrete synovial fluid, which lubricates the joint, reduces friction between cartilage surfaces, and nourishes the joint structures.
Usage
The term is used in medical, anatomical, and biological contexts to describe a specific structure within movable joints. - It is typically modified by the joint it lines (e.g., knee synovial membrane). - It is often discussed in relation to injury, disease (e.g., synovitis), or its physiological function.
Examples
- The synovial membrane of the knee can become inflamed due to overuse.
- During the surgery, the surgeon carefully examined the synovial membrane.
- Synovial fluid is produced and contained within the synovial membrane.
Advanced Usage
- Pathology: In conditions like rheumatoid arthritis, the synovial membrane becomes thickened and inflamed, leading to pain and stiffness.
- Medical Procedures: A synovial membrane biopsy may be performed to diagnose certain joint diseases.
