Skeletal/Muscular System

All movement in the body is controlled by muscles. Some muscles work without us thinking, like our heart beating, while other muscles are controlled by our thoughts and allow us to do stuff and move around. All of our muscles together make up the body's muscular system. 

Skeletal Muscles - These are the muscles we use to move around. They cover our skeleton and move our bones. Sometimes they are called striped muscles because they come in long dark and light bands of fibers and look striped. These muscles are voluntary because we control them directly with signals from our brains.

Smooth Muscles - Smooth muscles are special muscles that don't connect to bones, but control organs within our body. These muscles work without us having to think about them

Cardiac Muscle - This is a special muscle that pumps our heart and blood through our body.

Tendons connect muscles to bones. Tendons help form a connection between soft contracting muscle cells to hard bone cells.
