cartilaginous joint

Cartilaginous joints, also known as synchondroses, are joints where bones are connected by cartilage. These joints are typically transient, meaning they ossify (turn into bone) after birth. Examples include the connections between certain skull bones, which allow for growth during development. Juxta-epiphyseal plates, found in growing bones, are also cartilaginous joints that facilitate bone lengthening.1

Symphyses are another type of cartilaginous joint, characterized by fibrocartilage connecting the bodies of bones. Most symphyses are found in the vertebral column as intervertebral disks, which act as shock absorbers and allow for limited movement between vertebrae. The symphysis pubis, joining the pelvic bones, is another example that allows for flexibility, particularly during childbirth.2

Structurally, joints are classified by the connecting tissue and the presence of a joint cavity. Cartilaginous joints permit limited movement, unlike synovial joints which have a fluid-filled cavity and allow for a greater range of motion.3
