rectal sensation

Rectal sensation refers to the ability of the rectum—the last part of the digestive system—to detect the presence of stool or gas. This sensation involves nerves in the rectal wall that send signals to the brain, indicating whether the rectum is full or empty. Proper rectal sensation helps us recognize the need to use the bathroom and coordinate appropriate responses. When nerve function is normal, sensations are accurate, allowing timely and controlled bowel movements. If sensations are impaired, it may lead to issues like incontinence or difficulty sensing when the rectum is full.
