So this motor unit consists of a single motor neuron and only eight muscle cells. But if we examine this larger motor unit, this consists of many more of these muscle cells of many more of these muscle fibers inside the entire fascicle. And so because this motor unit consists of many more of these muscle cells, this larger motor unit will be able to exert a larger force. So that's what we mean by the size of the motor unit affects the magnitude of the force that is produced by that particular motor unit. Now let's move on to number two. So number two states that the number of motor units involved also affects the magnitude of the force that is produced.
