Fibrocartilage

Fibrocartilage is a type of cartilage that contains visible type I collagen fibers (known as fibrous collagen). It is found in areas where strong support and the ability to withstand heavy pressure are required.

Structure

Fibrocartilage is composed of small, chondrocytic cells, which are encapsulated within lacunae. These cells are surrounded by a dense network of collagen fibers. Unlike hyaline cartilage, fibrocartilage does not have a perichondrium. The collagen fibers in fibrocartilage are densely packed and arranged in an irregular manner. This gives the tissue its strength and resilience.

Function

The primary function of fibrocartilage is to provide support and absorb shock in the body. It is found in areas of the body that are subjected to heavy pressure, such as the intervertebral discs, menisci of the knee, and the pubic symphysis. Fibrocartilage also forms a part of the annulus fibrosus, which helps to keep the vertebral discs in place.

Clinical significance

Damage to fibrocartilage can lead to a variety of medical conditions. For example, a herniated disc occurs when the fibrocartilage of the intervertebral disc ruptures. This can cause severe pain and other symptoms. Similarly, damage to the menisci of the knee can lead to meniscus tears, which can cause pain and instability in the knee.
