The Muscular System

We all use our muscles to move our bodies. Without muscles, you would not be able to talk, eat, walk, sleep, or move at all. There are over 650 muscles that your body uses. These muscles are attached to the skeleton.

There are three types of muscles. They are the skeletal muscles, the cardiac muscles, and the smooth muscles. All of these muscles can tighten.

Some of these are voluntary muscles, and others are involuntary muscles. Voluntary muscles move only when we think about it. The muscles in our arms and legs work like this.

Involuntary muscles move when we aren’t even thinking about it. The heart is an example of an involuntary muscle. If we had to think about it to make our heart beat, we might forget.
