1. SKULL :
The bony part of head is called skull.
The skull is made up of 22 bones joined together. These bones are not
movable except the lower jaw bone.
It has two parts; the cranium or the brain box and the facial bones.
Out of 22 bones, 8 bones enclose the brain. The cranium covers and
protects the brain.
The other 14 are the facial bones, which support the face. The facial bones
form the upper and lower jaws and some other bones. The eye sockets are
also part of skull.
As only the lower jaw is the movable bone in the skull. This helps us to eat
and talk.
Both the lower and upper jaws have teeth.

2. BACKBONE :

vertebral column.

the hips.
