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: -Acetylcholine is a neurotransmitter found in the central nervous system (CNS) and peripheral nervous system (PNS). It plays an important role in many of your body’s functions, including muscle movement, memory and cognition, REM sleep, and attention and learning.
Detailed explanation-3: -Muscle contraction is controlled by receptors in the muscle cell membranes that respond to the neurotransmitter acetylcholine when it is released from motor neurons. Acetylcholine receptors are also found on neurons, where they perform a variety of important functions, including modulating cognition and addiction.
