Review: Pelvic nerves – from anatomy and physiology to clinical ...
WEBJan 1, 2021 · The PSN are the main source of parasympathetic nerves to the pelvic viscera and the hindgut. Presynaptic fibers arise from the brainstem (vagus nerve) or the sacral spinal cord segments S2–S4 (PSN), synapse in ganglia located close to or embedded in the organs from which postsynaptic fibers originate, and supply the end organs [ 30 ].
Pelvic splanchnic nerves: origin, course and function - Kenhub
WEBNov 3, 2023 · The pelvic splanchnic nerves (also called nervi erigentes) are the preganglionic parasympathetic nerve fibers that arise from the anterior rami of spinal nerves S2-S4 and freely distribute across the abdominal and pelvic cavities to innervate the abdominopelvic viscera.
Postganglionic nerve fibers - Wikipedia
WEBIn the autonomic nervous system, nerve fibers from the ganglion to the effector organ are called postganglionic nerve fibers.
Ganglia: Definition, location, function - Kenhub
WEBOct 30, 2023 · A ganglion is a collection of neuronal bodies found in the somatic and autonomic branches of the peripheral nervous system (PNS). Ganglia can be thought of as synaptic relay stations between neurons. The information enters the ganglia, excites the neuron in the ganglia and then exits.

WEBFeb 8, 2024 · Ganglia are clusters of nerve cell bodies found throughout the body. They are part of the peripheral nervous system (PNS) and carry nerve signals to and from the central nervous system (CNS). Ganglia are divided into two broad categories: the sensory ganglia and the motor ganglia (which are associated with the autonomic nervous system).
