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

Answer:
A muscle cell is made up of myofibrils, bundles of protein that includes actin and myosin. Muscle movement is powered by a change in shape of the myosin. The myosin head binds to actin and break down ATP. The myosin head tilt, which pulls up the actin and causes the muscle to contract.
