e. each motor unit can innervate a different number of muscle fibers.
Explanation:
Electromyography (EMG) is a diagnostic procedure used to measure the response of muscles and nerves to electrical activity. A motor unit is composed of one motor neuron and muscle fibers it innervates. The number of muscle fibers in each motor unit can vary among different muscles and even among motor units within the same muscle. Each motor unit is known to innervate a variable number of muscle fibers, but each single muscle fiber is innervated by only one motor.
