Anatomy of the Lower Rectum

Structure

The lower rectum is the final section of the large intestine, situated just above the anus. It plays a vital role in storing and expelling stool. The rectum measures about 12 centimeters in length and connects the sigmoid colon to the anal canal.

Blood Supply

Blood to the lower rectum is primarily provided by the superior rectal artery, which branches from the inferior mesenteric artery. Additional blood supply comes from the middle and inferior rectal arteries.

Nerve Supply

The lower rectum is innervated by both the autonomic and somatic nervous systems. The autonomic nerves control involuntary functions like muscle contractions, while somatic nerves manage voluntary movements, especially during defecation.

Types of Lower Rectum Disorders

Lower rectum disorders encompass a variety of conditions, including:

1. Hemorrhoids
2. Rectal Prolapse
3. Anal Fissures
4. Rectal Cancer
5. Inflammatory Bowel Disease (Crohn’s Disease and Ulcerative Colitis)
6. Diverticulitis
7. Rectocele
8. Rectal Varices
9. Rectal Abscess
10. Rectal Ulcers
