Synovial joints are often referred to by their geometric or mechanical structure.

Types of synovial joints include:

• Ball and socket joint
• Hinge joint
• Others

Tab 1 Ball and Socket Joint
The ball and socket synovial joint has one bone with a rounded head, a ‘ball.’
The other bone has a corresponding cavity, the ‘socket.’ The ball and socket joint is
usually multiaxial.




Tab 2 Hinge Joint
In the hinge joint, the geometry of the bony surfaces and the disposition of the
ligaments are such as to allow the parts to fold on each other, around
a single axis only.

Tab 3 Joints which Produce Specific Motions
There are other special arrangements of the synovial joints to
produce specific motions.

An example: Rotation of the head at the pivot-type joint of
atlas and axis (the upper two vertebrae).
