A motor unit is made up of a single nerve cell or neuron that innervates a group of skeletal muscles. The neurons receive signals from the brain and stimulate all the muscle fibers in that particular motor unit. Motor units are different depending on where they are and what they do. They also come in different sizes. There are small motor units that may only stimulate five or ten fibers to do things like blinking or sniffing. You also have motor units that include hundreds of muscle fibers. These are responsible for big movements like kicking or jumping.
