Synchondroses are a type of joint where the bones are connected by hyaline cartilage. This type of joint allows for limited movement and is typically found in areas where growth occurs, such as the growth plates in long bones. An example of a synchondrosis is the joint between the first rib and the sternum, which helps provide stability to the rib cage. These joints are classified as cartilaginous joints, meaning they are not as flexible as synovial joints, which allow for greater movement. Over time, some synchondroses can ossify, turning into bone as a person matures. This process is important for the proper development of the skeletal system.
