Pectinate Line Injuries

Anatomy of the Pectinate Line

Structure

The pectinate line, also known as the dentate line, is a visible ridge in the anal canal where the rectum transitions into the anal canal. It demarcates the upper two-thirds and lower third of the anal canal.

Blood Supply

• Above the Line: Supplied by the superior rectal artery (a branch of the inferior mesenteric artery).
• Below the Line: Supplied by the inferior rectal arteries (branches of the internal pudendal arteries).

Nerve Supply

• Above the Line: Innervated by autonomic nerves (no pain? sensation).
• Below the Line: Innervated by somatic nerves (sensitive to pain?, temperature, and touch).
