Pelvic pain is mediated by ?
Ans. is 'c' i.e., Autonomic nerves Visceral afferent fibers of pelvis travel with autonomic nerve fibers. Visceral afferent fibers conducting reflexive sensations (information that does not reach consciousness) travel with parasympathetic fibers to spinal sensory ganglia of S2- S4. The route taken by visceral afferent fibers conducting pain sensation differs in relation to an imaginary line, the pelvic pain line, that corresponds to the inferior limit of peritoneum, except in case of large intestine, where pain line occurs midway along length of sigmoid colon. Visceral afferent fibers that transmit pain sensations from the viscera inferior to pelvic pain line travel in parasympathetic fibers of the spinal ganglia S, - S4 ( pelvic splanchnic nerve or nerve erigentes). Visceral afferent fiber conducting pain from the viscera superior to pelvic pain line follow the sympatheitc fibers reterogradely to inferior thoracic and superior lumbar (Ti - Li 0,2 )spinal ganglia.
