Your shoulder joint allows you to raise your arm above your head.

ball and socket joint
The four kinds of movable joints are hinge joint, ball-and-socket, pivot joint, and gliding joint.Movable joint: allows forward or backward.Ball-and-socket joint: allows the greatest range of motion.Pivot joint: allows one bone to rotate around another.Gliding joint: allows one bone to slide over another.~ A. K. =)
The joint in a fan that allows it to swivel is called a ball joint. Ball joints work similarly to the human knee or hip when it comes to allowing motion.
Plain/gliding or sliding-All same no matter what u call it.
Hinge joints
*pivot joint-As the name suggests, this kind of joint permits pivotal movement of the parts of body this joined. Movement of the skull is an example. A man can turn his head from one side to the other by rotating the skull, which is joined to the backbone at its top in such a way that a pivotal movements is possible *hinge joint-This allows the movement of the part of body in one direction up or down but not sideways. Example of this joint is: knee-joint, elbow-joint, and movement of the lower jaw. *ball and socket joint-When a part is capable of making an all round movement up and down and sideways- this is possible by a joint of this kind. The leg can be moved in any direction, sideways, up and down *swivel joint- turn like a wheel on an axle. it is found between the vertebrae and the spine.
The kind of synovial joint form is the hinge joint, because of its primary uniaxial range of movement (as in shaking your head "yes") There is also a small amount of side to side bending which can be done, and rotation is possible at this joint.
an immoable is a fixed joint such as in the skull like a sutches. some kind of joint that doesnt move.
