Question

Briefly describe the different types of movable joints in the human body?

Accepted Answer

Most of the joints in the human body are freely movable. Movable joints can be further classified into the following four different types, depending upon type and extent of movement they allow:

(a) The ball and socket joint: In this type of joint, the ball shaped end of one bone fits into the hollow cup-shaped socket of the other bone. This joint allows maximum movement in all directions. The joint of the shoulder and hip are the examples of ball and socket joint.

(b) Hinge Joint: A hinge joint is like hinges in a door. We have hinge joints in our elbows, fingers, knees, and toes. This allows the movement of bones in one direction, that is up and down or back and forth.

(c) Pivot Joint: The joint where our neck joins the head is a pivot joint. It allows us to bend our head forward and backward and turn the head left or right.

(d) Gliding Joint: This kind of joint allows bones to glide each other, providing little movement in all directions. Gliding joints are found between the wrist and carpals and between the ankle and the tarsals.
