The pectinate line, also known as the dentate line, is a crucial anatomical landmark within the anal canal. Located approximately 2 cm above the anal verge (the opening of the anus), it divides the upper two-thirds and lower third of the anal canal. This line signifies the transition from the internal to the external parts of the anal canal, marking changes in tissue types, blood supply, nerve endings, and lymphatic drainage.
Blood Supply
- Above the Pectinate Line: The upper part of the anal canal receives blood from the superior rectal artery, a branch of the inferior mesenteric artery.
- Below the Pectinate Line: The lower section is supplied by the inferior rectal artery, a branch of the internal pudendal artery.
Nerve Supply
- Above the Pectinate Line: Sensation is mediated by autonomic nerves, meaning pain and temperature sensations are typically not felt.
- Below the Pectinate Line: The area is supplied by the inferior rectal nerves (somatic nerves), allowing for the perception of pain, temperature, and touch.
