A synchondrosis is a place in the body where two bones are directly joined together by cartilage. A type of joint. In some joints, the cartilage may turn into bone over time
Proteoglycans, which are cell molecules found in cartilage and hair, help in providing structure and support to these tissues. These molecules can also act as enzymes, catalyzing certain biochemical reactions, and function as transporters for various substances within the cells. Hormones, on the other hand, are signaling molecules that regulate different processes in the body and are not directly involved in forming cartilage or hair.
