Synarthrosis

Definition

Synarthrosis is a type of joint in the human body that permits very little or no movement, where the bones are closely joined either by fibrous tissue or cartilage. These joints are often found in areas requiring stability over mobility, such as the sutures in the skull.

Suture: A type of fibrous joint found only in the skull where bones are interlocked and bound together by connective tissue, allowing virtually no movement.

Fibrous joints: Joints made up of two or more bones that are connected purely by fibrous tissue, typically allowing for little to no mobility.

Cartilaginous joints: Joints where the bones are attached by cartilage, allowing for more movement than fibrous joints but less than the highly mobile synovial joints
