1.Support
The rigid skeleton forms a frame work for the support of the body. It raises the body above the ground. The vertebral column becomes a rigid axis to support the heavy head and to resist the push exercised by the limbs
2.Protection
It provides protection for delicate vital organs of the body.
The brain is protected by the cranium,eye by the orbit and inner ear by the optic
3.Muscle attachment
the bones serve as firm and adequate surfaces for attachment of muscles b means of tendons.
4.movement or Locomotion
Many bones act as levers.
When muscles pull these levers.they produce movement of the parts such as bring about locomotion.
Movement of the skeleton requires a system of joints and muscle attachment
5.Production of blood corpuscles
The long bones of vertebrates contain red marrow.
In amphibians,reptiles and birds the bone marrow forms all kinds of corpuscles,white corpuscles are formed in the lymphatic tissue.
