Muscles -- Front View (muscular system)

Each of your muscles is made up of thousands of thin, long, cylindrical cells called muscle fibers. The muscle fibers' highly specialized structure enables the muscles to relax and contract to produce movement. Muscles vary greatly in their shape and size, depending on their function.
