Muscles make possible every move we make, even when we are sleeping. Your muscles move according to what they are fromed. To be more specific, a muscle is made up of many bundles of muscle fibers. Each of these bundles of fibers is called a motor unit. Each unit has a motor nerve which branches out at its tip. Each muscle fiber, therefore, has its own nerve ending to stimulate it. An electrochemical impulse is transmitted by chemicals from the nerve ending to the fiber, causing the fiber in that motor unit to contract and this is how each muscle of your body moves.
When a muscle moves, it contracts and when it contracts, it shortens.
