    The motor unit:- One motor nerve can branch into tens, hundreds or even a thousand branches, each one terminating on a different muscle fibre. One motor nerve plus all of the fibres that it innervates is called a motor unit. A single muscle can consist of hundreds of motor units. For example, your rectus femoris (one of the 4 quadriceps muscles) might contain 1 million muscle fibres controlled by 1,000 motor nerves. So, on average, each motor unit contains 1,000 fibres. The fibre type composition of a single motor unit will always be all one type of fibre. So a single motor unit will consist entirely of either slow twitch or fast twitch.
