What type of cartilage is found at the ends of long bones?

Hyaline cartilage is the type found at the ends of long bones, as it provides a smooth, resilient surface for joint movements. This cartilage is crucial in the growth and development of long bones in children and serves as a cushion between bones in adults, minimizing friction during movement. Its composition, which includes a matrix of collagen fibers and a gel-like substance, allows it to maintain its shape while also providing flexibility and support.

In contrast, other types of cartilage serve different functions; for example, elastic cartilage, found in structures like the ear and epiglottis, offers more flexibility due to its higher elastin content. Fibrocartilage, which is tougher and denser, is primarily located in areas requiring additional strength, like intervertebral discs and the pubic symphysis. Cancellous cartilage is not recognized as a formal type of cartilage; rather, it may refer to spongy bone structure. Thus, the unique properties of hyaline cartilage make it the correct answer in this case.
