The Human Skeleton

The human skeleton consists of 206 bones. We are actually born with more bones (about 300), but many join together as we grow up.


The skeleton

protects the organs in the body.

supports parts of the body
Helps us move by providing a framework for the muscles and tendons to join to.

Some bones it is useful to know

Bone Use
Skull Protects the brain
Spine Supports the head
Spine Protects the spinal cord (a nerve that runs from the brain down the centre of the backbone
Femur (thigh bone) Supports the body
Ribs Protects the lungs



The muscles hold the skeleton in place and allows movement

Muscles, Tendons, and ligaments

Muscles can contract (get smaller)
Muscles are joined to bones by tendons
hold bones together

Muscles can only pull, they cannot push
This is why they nearly always work in pairs
When one muscle contracts (gets shorter) the other relaxes so can get longer
