The SPINAL CORD regulates the NERVE impulses that initiate the reflexive contractions of the rectum that result in bowel movements. The walls of the rectum are smooth and flexible, allowing it to expand to accommodate collected fecal material. The rectum is a frequent site of intestinal polyps and is vulnerable to CANCER. Other health conditions that can involve the rectum include ulcerative COLITIS, Crohn’s disease, and DIVERTICULAR DISEASE.
