Pivot (proximal and distal radioulnar joints, atlantoaxial joint)- rotation only
Condyloid (wrist joint, metacarpophalangeal joint, metatarsophalangeal joint)- contains a convex surface which articulates with a concave elliptical cavity. They are also known as ellipsoid joints.
Ball and socket (hip joint)-It permits free movement in numerous axes.
Joint class by movement
Synarthrosis – immovable.
Amphiarthrosis – slightly moveable.
Diarthrosis – freely moveable.
Types of cartilaginous joints
Synchondroses
In a synchondrosis, the bones are connected by hyaline cartilage. These joints are immovable (synarthrosis).
An example of a synchondrosis is the joint between the diaphysis and epiphysis of a growing long bone.
Symphyses
Symphysial joints are where the bones are united by a layer of fibrocartilage. They are slightly movable (amphiarthrosis).
Examples include the pubic symphysis, and the joints between vertebral bodies.
