Parts
The skeleton consists of five main parts :
The Skull

The skull is made up of 22 bones. Eight flat bones are
interlocked together. They give shape to the head. Fourteen

bones form the frame of the face. It protects the delicate
brain. It also protects the organs of sight, hearing, smell and

taste. The eyes fit in the eye sockets. The lower jaw is the only Skull
movable joint of the skull. This enables us to talk and eat.

The Vertebral Column

The vertebral column is made up of 33 small ring-shaped
bones called vertebrae . It runs from the base of the skull up to

the hip region. A type of tissue called cartilage is present
between most of the vertebrae. It cushions the bones and acts

as a shock absorber. The vertebral column encloses and
protects the spinal cord. Out of 33 vertebrae, the first seven

are present in the neck region.

Knowledge Plus Vertebral Column

More than half the bones in the human body are in the hands and feet.

The Ribs
There are 12 pairs of bow-shaped ribs. They are all

connected to the vertebral column at the back. Ten of

these rib pairs are connected to the breast bone,
called the sternum . The sternum is a flat bone in the

middle of the chest. The last two pairs of ribs form a
type of cage called the rib cage . This rib cage protects

Ribcage the heart and lungs.
The Limbs

The arms are also called forelimbs . Each forelimb has

three bones. The upper arm has one bone called
humerus. The lower arm has two bones called radius

and ulna . The wrist and hands are made up of many
small bones .
