There are five types of joints in our body:
(i) Fixed joints: Those joints which do not allow movement are called fixed joint. (ii) Ball and socket joint: This joint allows movement in all directions. The rounded end of one bone fits into the hollow space of other bone. For example, joint between upper arm and shoulder. (iii) Pivotal joint: This type of joint allow movement in all planes, i.e. up and down, side and other planes. For example, head.
(iv) Hinge joint: The joint which allows movement only in one plane is called hinge joint. For example, fingers, knees. (v) Gliding joint: These joints allow only a limited amount of movement of sliding nature of cartilage. For example, the joints of backbone.
