The neurotransmitter that is released at a neuromuscular junction that stimulates muscle contraction is:

Question

Quizplus · Accepted Answer

Acetylcholine is the main neurotransmitter released from motor neurons at neuromuscular junctions. It binds to receptors on the muscle fiber, causing a depolarizing event that ultimately leads to muscle contraction. Actin and myosin are proteins involved in muscle contraction, but they are not neurotransmitters. Epinephrine is a hormone released by the adrenal gland and is not directly involved in neuromuscular junctions. Dystrophin is a protein involved in muscle structure and is not related to neurotransmitter release or muscle contraction.
