Nerve fibres of the PSNS arise within the central nervous system. The primary nerves involved are cranial nerves. Below are some of the main cranial nerves in the PSNS: The PNS is made up of spinal nervetypes that project from the sacral region of the spinal cord (known as S2, S3, and S4). The sacrum nerves send signals to regions of the bladder, r...
Neurotransmitters are the chemical messengerswhich are transmitted through neurons. The preganglionic neuron’s primary neurotransmitter is acetylcholine. Acetylcholine is a neurotransmitter found in both the central nervous system and the peripheral nervous systemand plays a role in brain and muscle function. The preganglionic neurons within the th...
Dysfunctions within the PSNS can be varied and may only affect one or more organs. If the nerves in the system are damaged, this can interfere with messages sent between the brain and organs such as the heart, blood vessels, and sweat glands. If there is a surplus of the neurotransmitter acetylcholine, this can result in some side effects. As this ...
