The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
Our muscles need signals from our brains and energy from our food to contract and move. To build new muscles through exercise, we make use of their remarkable ability to repair themselves when damaged.
The five main functions of the muscular system are movement, support, protection, heat generation and blood circulation:
Movement. Skeletal muscles pull on the bones causing movements at the joints. ...
Support. Muscles of the body wall support the internal organs. ...
Protection. ...
Heat generation. ...
Blood circulation.
The three main types of muscle include:
Skeletal muscle – the specialised tissue that is attached to bones and allows movement. ...
Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. ...
Cardiac muscle – the muscle specific to the heart.
