A cartilaginous joint is a type of joint where two bones are connected by cartilage, a flexible and supportive tissue. These joints allow for limited movement, providing stability while still enabling some flexibility. Common examples include the joints between the vertebrae in the spine and the joint connecting the rib cage to the sternum. There are two main types of cartilaginous joints: synchondroses and symphyses. In a synchondrosis, the bones are joined by hyaline cartilage, while in a symphysis, they are connected by fibrocartilage. Cartilaginous joints play a crucial role in absorbing shock and maintaining the integrity of the skeletal system.
