Cartilaginous joint

Cartilaginous Joint

A cartilaginous joint is a type of joint in the human body that is connected primarily by cartilage. Cartilage is a type of connective tissue that is less rigid than bone but more flexible. Cartilaginous joints allow for only a little movability.

Types of Cartilaginous Joints

There are two main types of cartilaginous joints: synchondroses and symphyses.

Synchondroses

Synchondroses are a type of cartilaginous joint where the bones are united by hyaline cartilage. An example of a synchondrosis joint is the sternocostal joint (the joint between the sternum and the first rib).

Symphyses

Symphyses are a type of cartilaginous joint where the bones are covered with hyaline cartilage and the gap between the bones is filled with fibrocartilage. An example of a symphysis joint is the pubic symphysis, which is located between the two pubic bones.

Function of Cartilaginous Joints

The main function of cartilaginous joints is to provide stability and allow for only limited movement. This is because the cartilage that connects the bones in these joints is not as flexible as the synovial fluid found in synovial joints.

Clinical Significance

Diseases and conditions that can affect cartilaginous joints include osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. These conditions can cause pain and limit movement in the affected joints.
