Voluntary muscle makes up all of the muscles that you use to lift things, to run, to sit up, and to stretch. You can find smooth muscle in your internal organs. Cardiac muscle makes up your heart and is special because it tells itself when to contract and relax. One last type of body tissue is nerve tissue . This is important because it coordinates everything in your body.
Nerve tissue is composed of nerve cells, or neurons, bunched together to make a nerve.
Nerves transmit information from your body to your brain and back to your body again. Your finger touched the hot surface and a nerve sent that information from your finger to your brain. Your brain realized that the information said the stove was hot, so your brain sent a message to your hand muscle to move your finger. And that all happened in a fraction of a second. Well, for your body to be working right, all the skin and tissue in your body has to work right, also.
