Neuropathways in Parturition Anatomy
Splanchnic nerves, Greater, Lesser, Least, Celiac ganglion, Aorticorenal
ganglion, Superior mesenteric ganglion, Intermesenteric (abdominal aortic)
plexus, Lumbar splanchnic nerves, Sympathetic trunk and ganglia T11 spinal nerve
(anterior ramus), Rami communicantes, Subcostal nerve (T12), Inferior mesenteric
ganglion, T7 spinal nerve (anterior ramus), Intermesenteric (abdominal aortic) plexus,
Superior hypogastric plexus, S1 spinal nerve (anterior ramus),
Hypogastric
nerves, Pelvic splanchnic nerves, Inferior hypogastric (pelvic) plexus, Uterovaginal
plexus, Pudendal nerve (S2, 3, 4), Inferior anal (rectal) nerve, Motor fibers
to lower vagina and perineum via pudendal nerve (somatic), Sensory fibers from
lower vagina and perineum accompany somatic fibers via pudendal nerve to S2, 3,
4, Motor fibers to lower uterine segment, cervix, and upper vagina (parasympathetic),
Sensory fibers from cervix and upper vagina accompany pelvic splanchnic nerves (parasympathetic)
to S2, 3, 4, Motor fibers to uterine body and fundus (sympathetic), Sensory
fibers from uterine body and fundus accompany sympathetic fibers via hypogastric
plexuses to T11, 12 (L1?), Iliohypogastric nerve (L1), Ilioinguinal nerve (L1),
Vesical plexus, Dorsal nerve of clitoris, Posterior labial nerves.
