Lymph drainage area superior to pectinate line drains to which nodal groups?

Explanation:
Lymphatics above the pectinate line follow the hindgut pattern, traveling with the superior rectal vessels to the inferior mesenteric lymph nodes (and then on to lumbar/para-aortic nodes). That area drains to the inferior mesenteric group, reflecting its endoderm-derived, visceral nature. In contrast, below the line lymphatics go to the superficial inguinal nodes, along the inferior rectal vessels.
