A neurotransmitter that is important in muscle contraction is:

Question

Quizplus · Accepted Answer

Acetylcholine is the neurotransmitter that is important in muscle contraction. It is released at the neuromuscular junction and binds to receptors on the muscle fibers, initiating a muscle contraction. Epinephrine and norepinephrine are more involved in the fight or flight response and not directly related to muscle contraction. Dopamine is important for movement and mood regulation, but not muscle contraction specifically.
