Accepted Answer

Skull: There are 22 bones in the skull which protect the most important organ, the brain. It is the movement of the lower jaw that helps us to eat and speak.

Pivot joint: The joint which joins the skull to the backbone is the pivot joint. It enables the head to move up, down and sideways.

Ball and socket joint: The shoulder and hip region have the ball and socket joint. They allow movement in all directions. This joint helps in the maximum movement of the body.

Ribcage: There is a cage of bones around the chest which is called the ribcage. The ribcage protects the heart and the lungs. It is made up of 12 pairs of thin curved bones that are attached to the backbone at the back and to a flat bone called the sternum in the front.

Hinge joint: It is like the hinge of the door and helps the bones to move in one direction. The elbows, knees, fingers and toes have hinge joint. They can only move forward and backwards.

Backbone: A series of small bones form the backbone of the human body, these are called the vertebrae or the vertebral column. It is a strong column that is made of 33 small bones. The vertebrae are hollow in the centre and protect the spinal cord. The skull is attached to the spine or the backbone through these vertebrae.
