Examples of amphiarthroses include the intervertebral disks of the spine and the pubic symphysis of the hips. The sutures of the skull and the gomphoses that connect the teeth to the skull are examples of synarthroses.Īn amphiarthrosis allows a slight amount of movement at the joint. ![]() Joints may be classified functionally based upon how much movement they allow.Ī joint that permits no movement is known as a synarthrosis. ![]()
