In patients with poliomyelitis, motor neurons are destroyed, causing loss of muscle function and even flaccid paralysis. Sometimes recovery occurs because of the formation of axon branches from the remaining motor neurons. These branches innervate the paralyzed muscle fibers to produce motor units with many more muscle fibers than usual, resulting in the recovery of muscle function. Explain what effect this reinnervation of muscle fibers would have on the degree of muscle control in a person who has recovered from poliomyelitis.
