Question

the neurotransmitter that controls skeletal muscle contraction is ______. multiple choice acetylcholine nitric oxide gaba norepinephrine

In the nervous system, acetylcholine is the neurotransmitter that is responsible for signaling skeletal muscle contraction. GABA is an inhibitory neurotransmitter in the brain, nitric oxide has other signaling roles (not primarily for skeletal muscle contraction), and norepinephrine is involved in other physiological processes like the fight - or - flight response and not skeletal muscle contraction.

Answer:

acetylcholine (the option corresponding to acetylcholine)
