Smooth Muscles
Cardiac Muscles :Cardiac Muscles Cardiac muscles are the muscles in your heart. They work together to pump blood through your body. Cardiac muscles work all by themselves.
Skeletal Muscles :Skeletal Muscles Skeletal muscles are the muscles that we control. We use them to walk and lift. They work with your skeleton to give your body power and strength. They are usually attached at one end to a bone.
