Quizplus · Accepted Answer

Acetylcholine is the neurotransmitter that is needed to transfer messages from a motor neuron to a leg muscle. It is released from the motor neuron's axon terminals at the neuromuscular junction and binds to acetylcholine receptors on the muscle fiber, leading to muscle contraction. Dopamine and epinephrine are neurotransmitters involved in other functions such as reward and stress response, while oxytocin is involved in social bonding and childbirth.
