What are the 3 main functions of your skelaton?

The skeleton has six functions.

1)Support forms the framework that supports the body and maintains its shape

2)Movement joints between the bones allow movement powered by skeletal muscles.

3)Protection for the internal organs eg heart,lungs,major blood vessels are protected by the ribs and sternum, the brain is protected by the skull, the vertebrae protects the spinal column, lower organs by the spine and pelvis.

4)Blood Cell Production blood cells are produced in the bone marrow (haematopoiesis)

5)Storage of calcium inside the bone matrix (used in calcium metabolism) and the storage of iron as ferrotin in bone marrow (used in the metabolism of iron)

6) Regulation of Endocrine bone cells release osteocalcin that helps in regulating blood glucose and fat deposits.
