"cartilage bone"の定義と意味

What is a "cartilage bone"?

A cartilage bone, also known as endochondral bone, is a type of bone that develops from a cartilage template. During the process of endochondral ossification, cartilage is gradually replaced by bone tissue, forming the structure of the bone. This type of bone is found in various parts of the body, such as long bones (e.g., femur, humerus), the vertebral column, and the base of the skull. Cartilage bone provides support, strength, and flexibility to the skeletal system, allowing for movement and protecting vital organs. It consists of a combination of calcified bone matrix and remnants of cartilage, preserving some of the original cartilaginous characteristics.
