Cartilaginous joints are a type of joint in the human body where the bones are connected by cartilage, a flexible and durable tissue. These joints allow for limited movement, providing stability while still enabling some flexibility. Examples of cartilaginous joints include the joints between the vertebrae in the spine and the connection between the ribs and the sternum. There are two main types of cartilaginous joints: synchondroses and symphyses. Synchondroses are joints where the bones are joined by hyaline cartilage, such as the growth plates in long bones. Symphyses, on the other hand, are joints where the bones are separated by a pad of fibrocartilage, like the pubic symphysis in the pelvis.
