What Are the Main Functions of the Muscular System?
The two major functions of the muscular system are the ability to make the body move and the posture of the body. The muscles enable the arms, legs and other parts of the body to move while keeping the body in an upright or sitting position without falling over.
Muscles are attached to nearly every bone in the body. The body has around 700 muscles that each have different and important functions. These muscles help aid in physical movement as well as internal movement. Digestion and respiratory functions are both controlled by the muscles surrounding the organs. The heart also contains muscles that allow it to be able to beat while pushing blood throughout the body.
There are three major types of muscles in the body. The visceral muscles are the muscles that help control the functioning of the organs. They are involuntary muscles and are used for survival of the body. These muscles also help people stand without falling over or becoming contorted. The cardiac muscles are the muscles that control the functioning of the heart. The skeletal muscles are the muscles that are attached to the bones and are able to help the body move; they are voluntary muscles that contract to allow movement and locomotion of the body.
