When the ______ reaches the ends of the axon, the neurotransmitter is released and diffuses to to the muscle cell membrane to combine with receptors there.19.8. Nerve impulse. When the ______ reaches the ends of the axon, the neurotransmitter is released and diffuses to to the muscle cell membrane to combine with receptors there.
