Definition: The term "chondroglossal" refers to a type of bone that is found in the neck. It consists of two layers, known as the cartilage and the chondroitin sulfate matrix. The cartilage layer provides support for the bones, while the chondroitin sulfate matrix provides lubrication and helps maintain the shape of the bone. Chondroglossal bone is a type of osteoblast, which are responsible for the formation of new bone tissue.
