The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions — support, movement, protection, blood cell production, calcium storage and endocrine regulation — that enable us to move through our daily lives
The primary job of muscle is to move the bones of the skeleton. It also makes the heart beat and constitutes the walls of other important hollow organs.
There are three types of muscle tissue:
Skeletal muscle – creates movement in the body.
Cardiac muscle: involuntary muscle that makes up the walls of the heart. (This muscle type also creates the electrical impulses that produce the heart’s contractions
Smooth muscle: Another involuntary muscle type, makes up the walls of hollow organs, respiratory passageways, and blood vessels.
Muscular disorders and conditions that affect muscles include:
