Cartilaginous joint
Cartilaginous Joint
A Cartilaginous Joint (pronunciation: /kɑːr.tɪ.ləˈdʒɪ.nəs dʒɔɪnt/) is a type of joint in the human body where the bones are connected by cartilage. The term is derived from the Latin words cartilago meaning "gristle" and junctus meaning "joined".
Types
There are two types of cartilaginous joints: synchondroses and symphyses.
- Synchondroses are joints where the bones are connected by hyaline cartilage. An example of a synchondrosis is the joint between the diaphysis and epiphysis of a growing long bone.
- Symphyses are joints where the bones are connected by a pad of fibrocartilage. An example of a symphysis is the pubic symphysis in the pelvis.
Function
Cartilaginous joints allow for limited movement and provide a cushion between bones that bear weight and receive shock. They are found in areas of the body that need to be both strong and flexible, such as the spine and rib cage.
