Anatomy of the Lower Rectum
Structure
The lower rectum is the final section of the large intestine, connecting the sigmoid colon to the anal canal. It plays a crucial role in storing and expelling feces during bowel movements. The rectum is approximately 12 centimeters long and is divided into three parts: upper, middle, and lower rectum.
Blood Supply
The lower rectum receives blood primarily from the superior rectal artery, a branch of the inferior mesenteric artery. Additional blood flow comes from the middle rectal arteries (branches of the internal iliac arteries) and the inferior rectal arteries (branches of the internal pudendal arteries).
Nerve Supply
Nerve supply to the lower rectum is provided by the autonomic nervous system, including the inferior hypogastric plexus. This network controls involuntary functions such as bowel movements and maintains sphincter tone, which regulates the release of stool.
Types of Lower Rectum Diseases
Lower rectum diseases encompass a variety of conditions that affect the rectum’s structure and function. Common types include:
- Hemorrhoids: Swollen blood vessels in the rectum or anus.
