This system allows movement and function

It is controlled by several aspects including the nervous system. The heart is self controlled or “autonomous”.

Three main Categories of Muscle

   -  Skeletal Muscle
   -  Cardiac Muscle
   -  Smooth Muscle

There are approximately 639 muscles in the human body

Muscle mass takes up approximately 1/2 the weight of your body

Skeletal muscles control the movement of the body. They allow for movement of bones and joints. Most are voluntary movement – This means that conscious thought moves the muscles

Cardiac muscles control your heart. The control is considered a self control,
which means that your mind can’t control the beating of the heart. This is
called involuntary

Smooth muscles are controled by the brain. Most smooth musces are involuntary.
This type of muscle is somewhat different then the two previously mentioned.
