What characterizes fibrocartilage?

Fibrocartilage is characterized by its strong and tensile properties, which enable it to provide significant support in various areas of the body. This type of cartilage contains a dense network of collagen fibers, which give it durability and the ability to withstand pressure and tension. It is found in structures that require a combination of strength and some degree of flexibility, such as intervertebral discs, the pubic symphysis, and the menisci of the knee.

The presence of collagen fibers is crucial, as they allow fibrocartilage to absorb shock and resist deformation, making it ideal for its supportive roles in weight-bearing joints and areas subjected to mechanical stress. This differentiates fibrocartilage from other types of cartilage, such as hyaline cartilage, which is smoother and more glassy in appearance, or elastic cartilage, which is more flexible and found in areas requiring elasticity like the ear and epiglottis. Fibrocartilage’s unique composition is particularly suited for its functions in joint stability and load distribution.
