A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles.

Answer:

when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron. The neuromuscular junction is the name of the place where the motor neuron reaches a muscle cell.
