Which excitatory neurotransmitter is directly responsible for muscle contraction in vertebrates?

Question

Quizplus · Accepted Answer

Acetylcholine is the neurotransmitter responsible for muscle contraction in vertebrates. It binds to receptors on the muscle cells, causing a depolarization of the muscle membrane and resulting in muscle contraction. Dopamine and norepinephrine are involved in other functions such as reward and attention, while nitrous oxide is a gas and not a neurotransmitter. Glutamate is an excitatory neurotransmitter in the brain, but not involved in muscle contraction.
