What is the primary function of fibrocartilage?

The primary function of fibrocartilage is to act as a shock absorber. It is a type of cartilage that is particularly dense and tough, containing a high concentration of collagen fibers. This composition allows fibrocartilage to withstand heavy pressure and reduce the impact of forces on the joints, particularly in areas like the intervertebral discs, pubic symphysis, and within certain joints such as the knee. By providing cushioning and support, fibrocartilage plays a crucial role in maintaining the structural integrity of the joints under stress.

The choices related to elasticity, connection of bone to bone, and facilitation of movement do not accurately capture the primary role of fibrocartilage. While it does contribute to the overall stability of the skeletal system, the most significant aspect of its function is its shock-absorbing capability, which is vital for protecting underlying structures from injury during physical activity.
