피각연골, or hyaline cartilage, is a type of connective tissue found in various parts of the body. It is smooth and glassy in appearance, providing support and flexibility. This cartilage is essential for the development of bones in embryos and is present in areas such as the nose, trachea, and the ends of long bones, where it helps reduce friction during joint movement. In addition to its structural role, 피각연골 plays a crucial part in the growth of long bones through a process called endochondral ossification. This process allows the cartilage to gradually be replaced by bone tissue as a person matures. Its unique properties make it vital for maintaining healthy joints and overall skeletal function.
