Correct option is A
The Correct Answer Is: (A) Synovial fluid
Explanation:
The lubricating fluid found between two bones at a movable joint is called synovial fluid.
It is secreted by the synovial membrane and plays a crucial role in reducing friction, allowing smooth movement of the joints.
Synovial fluid also nourishes the cartilage and acts as a shock absorber during movement. Movable joints, such as the knee, elbow, and shoulder, contain this fluid.
Information Booster:
- Synovial fluid contains hyaluronic acid and lubricin, which help in lubrication.
- Examples of synovial joints: Hinge joints (knee, elbow), Ball and socket joints (hip, shoulder).
