The Role Of Bones In The Human Body

There are on average 206 individual bones in an adult human skeleton, which are both metabolically active and highly vascularised. Bones have many important roles within the human body, for example they provide structure and support for the fleshy tissue, protection of vital organs eg the brain in the cranial cavity, storage for vital materials eg calcium and phosphorus and also enables movement of the body as the bones provide a surface for ligament, muscles and tendons to attach to. The bones also play a role in blood production of both white and red blood cells as bone marrow is stored in the central cavity of long bones. The 206 individual bones can be divided in to 5 subgroups of bone, these are;
1) Long bones eg Femur and Humerus
2) Short
