Acetylcholine (ACh) is the only neurotransmitter used in the motor division of the somatic nervous system. It works by binding to acetylcholine receptors on skeletal muscle fibers and opening ligand-gated sodium channels in the cell membrane.

The neurotransmitter in a somatic motor pathway is acetylcholine. It is released by motor neurons at the neuromuscular junction to stimulate muscle contraction.
Acetylcholine
Yes, acetylcholine is the substance released by the axon terminals of both somatic motor neurons and postganglionic parasympathetic neurons. In the somatic nervous system, acetylcholine is released at the neuromuscular junction, while in the parasympathetic nervous system, it is released at synapses with target organs.
It varies: In the somatic system (skeletal muscle) and parasympathetic branch of the autonomous nervous system (smooth & cardiac muscle) it is usually acetylcholine. In the sympathetic branch of the autonomous nervous system (smooth & cardiac muscle) it is usually norepinephrine (also called noradrenaline). There are exceptions, but this is the general rule.
The somatic division of the peripheral nervous system controls voluntary movements, such as skeletal muscle contractions. It also transmits sensory information from the skin, muscles, and joints to the central nervous system for processing.
Synaptic vesicles in the axon terminals of neurons contain acetylcholine. Acetylcholine is a neurotransmitter that is released from these vesicles into the synaptic cleft to transmit signals to target cells or other neurons.
Somatic Nervous System
The somatic nervous system allows us to consciously control our skeletal muscles.
somatic nervous system. It is responsible for voluntary movements and relays sensory information to the central nervous system for processing.
Acetylcholinesterase is an enzyme that breaks down the neurotransmitter acetylcholine into choline and acetate. This breakdown is essential for terminating the signal transmission at cholinergic synapses and preventing excessive stimulation of the postsynaptic receptors.
