Explanation:
Detailed explanation-1: -Muscle contraction is controlled by receptors in the muscle cell membranes that respond to the neurotransmitter acetylcholine when it is released from motor neurons.
Detailed explanation-2: -Acetylcholine, a substance synthesized by neurons, is the primary neurotransmitter of the parasympathetic nervous system, which controls smooth muscle contraction and blood vessel dilation and slows heart rate.
