A cartilage disc is a structure made of fibrous cartilage, found in specific areas of the body, most notably as intervertebral discs.
Fibrous Cartilage and its Location
Fibrous cartilage is a tough type of cartilage characterized by its high content of collagen fibers. According to the provided reference, it's present in:
- Intervertebral discs: These discs are located between the vertebrae of the spine.
- Pubic symphysis: This is the joint where the left and right pubic bones meet in the pelvis.
Composition of Fibrous Cartilage
Fibrous cartilage is primarily composed of:
- Collagen Fibers: Abundant, white-colored collagen fibers that provide strength and resilience. These fibers are the key feature of this type of cartilage.
Function of Cartilage Discs
Cartilage discs provide crucial functions in the body:
- Support: They offer structural support, particularly in the spine.
- Shock Absorption: They act as shock absorbers, reducing the impact on bones during movement.
- Flexibility: While strong, they allow for a degree of flexibility.
In summary, a cartilage disc composed of fibrous cartilage provides structural support, flexibility, and shock absorption in locations such as the spine and pelvis.
