What is the advantage of having few muscle cells per motor unit?

Having few muscle cells per motor unit allows for precise and fine motor control, as each motor neuron can individually stimulate a small number of muscle fibers. This arrangement is particularly beneficial for tasks requiring delicate movements, such as those performed by the fingers or eyes. In contrast, a larger number of muscle cells per motor unit typically results in greater force generation but less control. Thus, the balance between muscle cell quantity and motor unit size is crucial for optimizing both strength and precision in muscle function.
