In these joints, the discs improve the congruence (area over which the joint reaction forces are distributed) and stability of the joints. In addition, the discs deform in response to loading and, thereby, provide shock absorption.

What is the function of a fibrocartilage?

Fibrocartilage provides the tough material of the intervertebral discs; the intraarticular cartilages of the knee, wrist and temporo-mandibular joints; the articular cartilage of the temporo-mandibular joint and of the joint between the clavicle and the sternum.

Which cartilage serves as shock absorber?

Articular cartilage acts as a shock absorber, cushioning bones against impacting each other during a weight-bearing activity, such as walking or jogging.
