Skeletal System Posterior

Primary function of the Skeletal System is the formation of a solid framework for supporting and protecting the body organs and holding the Skeletal Muscles. Axial Skeleton bones act as a hard cover for protecting internal organs like Brain and Heart from external injuries. Appendicular Skeleton bones gives support and flexion at joints while holding the muscles moving the limbs. One of the functions of Skeletal System is to provide attachment points for Skeletal Muscles.

Bones of Skeletal System has Medullary Cavity containing Red Bone Marrow for production of red blood cells and white blood cells in a process called Hematopoiesis. It also contains many important substances for helping in growth and repair of body like Calcium, Osteocalcin (hormone regulating blood sugar and fat), and energy present in form of Lipids in Yellow Bone Marrow and Red bone marrow containing Iron to form Hemoglobin (iron containing oxygen transport metalloprotein) in red blood cells.
