The pelvic splanchnic nerves are featured as a key plot point in "Parasites Lost", a 2001 episode of the American animated TV comedy Futurama; when protagonist Philip J. Fry is infected with parasitic worms, the rest of the crew use micro-droids to enter his body with the intention of tickling the pelvic splanchnic ganglion to trigger a convulsive bowel movement that they believe will expel ...
Cardiopulmonary nerves: Postsynaptic: sympathetic: cervical and upper thoracic ganglia: Thoracic cavity: Thoracic splanchnic nerves: generally: Presynaptic: lower thoracic ganglia: Prevertebral ganglia: Greater splanchnic nerve: T5–T9 or T10: Celiac ganglia: Lesser splanchnic nerve: T10–T11: Superior mesenteric ganglia and Aorticorenal ...
The pelvic splanchnic efferent preganglionic nerve cell bodies reside in the lateral gray horn of the spinal cord at the T12–L1 vertebral levels (the spinal cord terminates at the L1–L2 vertebrae with the conus medullaris), and their axons exit the vertebral column as S2–S4 spinal nerves through the sacral foramina.

hypogastric nerve - a continuation of either superior hypogastric plexus. [3] [better source needed] sacral splanchnic nerves (from sympathetic trunk) [citation needed] pelvic splanchnic nerves (from sacral nerves S2-S4) also contribute parasympathetic efferent fibers to the plexus. [citation needed]
The sacral sympathetic nerves contain a mix of preganglionic and postganglionic sympathetic fibers, but mostly preganglionic. They also contain general visceral afferent fibers. They are found in the same region as the pelvic splanchnic nerves , which arise from the sacral spinal nerves to provide parasympathetic fibers to the inferior ...
The superior hypogastric plexus receives contributions from the two lower lumbar splanchnic nerves (L3-L4), which are branches of the chain ganglia. They also contain parasympathetic fibers which arise from pelvic splanchnic nerve (S2-S4) and ascend from inferior hypogastric plexus; it is more usual for these parasympathetic fibers to ascend to the left-handed side of the superior hypogastric ...
“The nerve samples are sliced by what’s called an ultra microtome to these very, very minuscule sections, that are then magnified over 1,000 times and counted basically with an automated ...
It allows nerve fibres to travel to spinal nerves that are superior and inferior to the one in which they originated. Also, a number of nerves, such as most of the splanchnic nerves , arise directly from the trunks.
