What neurotransmitter control the somatic nervous system and how does it work?
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.

What is the neurotransmitter in a somatic motor pathway?
The neurotransmitter in a somatic motor pathway is acetylcholine. It is released by motor neurons at the neuromuscular junction to stimulate muscle contraction.
The neurotransmitter released by somatic motor neurons is?
Acetylcholine
Is acetylcholine the substance released by the axon terminals of both somatic motor neurons and postganglionic parasympathetic neurons?
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.
What Neurotransmitter diffuses across a synapse to a muscle cell?
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.
What is controlled by the somatic division of the PNS?
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.
Which structure contains vesicles with acetylcholine?
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.
What is the name of the division of the nervous system that exclusively controls skeletal muscles?
Somatic Nervous System
Which of the following allows us to consciously control your skeletal muscles somatic nervous system sympathetic division of the sutonomic nervous system the involuntary nervous system or the parasymp?
The somatic nervous system allows us to consciously control our skeletal muscles.
The division of the nervous system that regulates activities that are under conscious control is the?
somatic nervous system. It is responsible for voluntary movements and relays sensory information to the central nervous system for processing.
What is the role of acetylcholinesterase?
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.
