A motor neuron releases the neurotransmitter _______ into the synaptic cleft.

Question

Quizplus · Accepted Answer

Motor neurons release the neurotransmitter acetylcholine into the synaptic cleft, which binds to receptors on the membrane of the muscle cell, causing depolarization and ultimately leading to contraction. Myosin is a protein involved in muscle contraction, but it is not a neurotransmitter. Lactic acid is a byproduct of cellular metabolism, and ATP is a molecule involved in energy transfer, but neither is a neurotransmitter released by motor neurons.
