Which location is specifically associated with fibrous cartilage?

Fibrous cartilage is a type of connective tissue that is known for its high tensile strength and ability to withstand pressure. It is characterized by a dense network of collagen fibers, which provide both strength and support while allowing for some flexibility.

The correct association for fibrous cartilage is primarily found in structures that require durability and resilience due to high levels of stress and strain. The intervertebral discs, located between the vertebrae in the spine, and the menisci in the knee joint serve this purpose exceptionally well. Both structures are subjected to significant mechanical loads during movement and activity, making fibrous cartilage the ideal type of cartilage in these areas.

In contrast, the other options represent different types of cartilage. For example, the cartilage in the trachea is primarily hyaline cartilage, which provides support and maintains the airway structure. The articular ends of long bones, which are covered by articular cartilage, are also predominantly hyaline cartilage to facilitate smooth joint movement. The cartilage of the eustachian tube, intended to maintain the patency of the tube, consists of elastic cartilage, which is more flexible than fibrous cartilage. Thus, option C accurately reflects the typical location of fibrous cartilage, highlighting its role in sustaining mechanical stress
