The pectinate line in the anal canal demarcates an important anatomical and functional boundary. Located approximately two-thirds of the way down the canal, it separates the upper columnar epithelium from the lower stratified squamous epithelium. This line corresponds to differences in embryological origin, venous drainage, lymphatic drainage, and nerve supply. The region above the pectinate line is sensitive to stretch, while below it is sensitive to pain, temperature, and touch. Understanding this distinction is crucial in surgical procedures, management of hemorrhoids, and assessment of anorectal pathologies.
