1. Be able to define synarthrosis, amphiarthrosis, and diarthrosis. Be able to give  examples of each type of joint. Joints are functionally classified according to the degree of movement they permit. There are  three joints classification: 1.synarthrosis, 2.amphiarthrosis and 3. diarthrosis. Synarthrosis is an  unmovable joint. Examples of synarthroses are: sutures (frontal suture), gomphoses (mandible),  and   synchondrosis   (epiphysis).   Amphiarthrosis   is   a   slightly   moveable   joint.   Examples   of  amphiarthroses are: syndesmosis (distal tibiofibular joint) and symphysis (public symphysis).  Diarthrosis is a freely moveable joint. All diarthroses are synovial joints. Examples of diarthroses  are:   planar   (intercarpal,   intertarsal,   sternocoastal),   hinge   (elbow,   ankle),   pivot   (atlanto-axial  radioulnar joints), condyloid (radiocarpal metacarpophalangeal joints), saddle (carpometacarpal  joint), and ball-and-socket (shoulder, hip joints).  2. Be able to identify the different diarthrotic joints. Give examples of each. Be able to  identify which movements are found at each type of diarthrotic joint.  There are six diarthrotic joints: planar joints, hinge joints, pivot joints, condyloid joints, saddle  joints, and ball-and-socket joints. In planar joints, the articulating surfaces of bones are flat or
