The large intestine is primarily innervated by the autonomic nervous system, specifically the vagus nerve (cranial nerve X) for the proximal part, and by the pelvic splanchnic nerves (S2-S4) for the distal part. The vagus nerve supplies the cecum, ascending colon, and part of the transverse colon, while the pelvic splanchnic nerves innervate the descending colon, sigmoid colon, and rectum. Additionally, sensory fibers from the inferior mesenteric ganglion contribute to the innervation.
