Pelvic splanchnic nerves

Pelvic splanchnic nerves are nerves that arise from the spinal cord in the lower back region (specifically from the sacral segments S2 to S4). They carry parasympathetic signals, which help regulate involuntary functions of the pelvic organs such as the bladder, rectum, and reproductive organs. These nerves are essential for processes like urination, bowel movements, and sexual function. They connect the spinal cord to these organs, transmitting signals that promote relaxation and activity needed for normal pelvic organ function.
