Skeletal system consists of the all the bones which constitute the body frame.
The muscles are the compound tissues which align these bones by their attachment to the bones. Voluntary and involuntary movements of the skeletal framework is brought by the muscles.
Muscles also form a structural and functional constituent tissue of some of the organs like the heart and Digestive system.
Contraction and relaxation of these muscles bring about the delicate and complex activities of the body.
FUNCTIONS OF MUSCULOSKELETAL SYSTEM
- The skeletal system serves as a framework for tissues and organs to attach themselves to this system acts as a protective structure for vital organs. Major examples of this are the brain being protected by the skull and the lungs being protected by the rib cage.
- All Sorts of Movements
- Shape and Structure to the body
- Yellow and Red bone marrow are located in the long bones. Yellow marrow has fatty connective tissue where red marrow erythrocytes, platelets, and leukocytes migrate to the blood to do their special tasks.
- Another function of bones is the storage of certain minerals. Calcium and phosphorus are among the main minerals being stored. The importance of this storage "device" helps to regulate mineral balance in the bloodstream.
Diseases of Musculoskeletal System:
