Skeleton - Movement and Locomotion — Question 2

Uses of skeleton:

1. Support and shape — The skeletal system provides a framework to the body. It provides support to all soft parts and gives a definite shape to the body and all body parts.
2. Protection — Several delicate and important organs are well protected by a casing of bones.
   Example — The skull provides protection to the delicate brain.
3. Movement — Some bones are movable on each other which is brought about by the action of muscles that originate on one bone and are inserted into another.
4. Leverage — Some bones and joints form levers which causes the increase in the speed and distance of the muscle movement.
5. Formation of blood cells — Certain types of blood cells including red and white blood cells are formed in the marrow of certain long bones such as the femur.
6. The bones are storehouse of calcium and phosphorus for the rest of the body.
