Types of muscle Muscle is made of strong tissue that can contract in an orderly way. Your body has three types of muscle tissue Skeletal muscle Smooth muscle Cardiac muscle Some muscles involuntary and some are voluntary Involuntary: some muscles are not under your conscious control. (breathing and digesting food) Voluntary: muscles that are under your conscious control

Skeletal muscle The type of muscle that attaches to bones is skeletal muscle. Skeletal muscle are the force that moves your bones. Voluntary muscles, which are muscles under you conscious control. At the end of each skeletal muscle is a tendon (is a strong connective tissue that attaches muscle to bone. Skeletal muscles are sometimes referred to as striated muscles. Striated muscle cells appear banded. React quickly and tire quickly

Smooth muscle Are involuntary muscles named for their smooth appearance. Found inside many internal organs. (stomach, blood vessels) They work automatically to control certain movements inside your body. (digestion) React more slowly and tire more slowly.

Cardiac muscle Are found only in the heart. Cardiac muscles are involuntary Cardiac muscles are striated. Cardiac muscles do not get tired.

Functions of the muscular system There are four functions of the muscular system Movement: bone movement, blood movement, food movement Stability: attached to bone support and balance body. Look at the back of your hand move your fingers. These are tendons. Tendons work with muscle to keep the joints in place when your body moves. Protection: muscles cover most of your skeleton. Muscles cover organs inside your body. Temperature regulation: shivering is when muscles contract rapidly and change chemical energy into thermal energy. Thermal energy helps raise your body’s temperature.
