What is the name of the neurotransmitter responsible for muscle contractions?

Question

Quizplus · Accepted Answer

Acetylcholine is the neurotransmitter responsible for muscle contractions. When a nerve impulse reaches the end of a motor neuron, acetylcholine is released into the synaptic cleft and binds to receptors on the muscle fiber, leading to muscle contraction. Calcium and potassium also play important roles in muscle function, but they are not neurotransmitters. Lactic acid is produced during muscular activity, but it is not a neurotransmitter and does not directly cause muscle contractions.
