Synarthrosis
Suture lines of the skull where adjoining cranial plates are separated by thin fibrous tissue.
Amphiarthroses
Adjacent bones are bound by flexible fibrocartilage that permits limited motion to occur.
For example the pubic symphysis, part of the sacroiliac joint, and intervertebral discs.
Diarthroses
These are the most common and most mobile joints. All have a synovial lining. They are subclassified into ball and socket (hip), hinge (interphalangeal), saddle (first carpometacarpal), and plane (patellofemoral) joints.
