Detailed explanation-1: -Acetylcholine has different roles and functions at different synapses throughout the body. In the somatic nervous system, acetylcholine is used at the neuromuscular junctions, triggering the firing of motor neurons and affecting voluntary movements.
Detailed explanation-2: -These vesicles contain neurotransmitters, which are chemical messengers that are responsible for the transmission of the message. In the case of the neuromuscular junction, the neurotransmitter is acetylcholine (Ach).
Detailed explanation-3: -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.
