The internal iliac lymph nodes (or hypogastric) surround the internal iliac artery and its branches (the hypogastric vessels), and receive the lymphatics corresponding to the distribution of the branches of it, i. e., they receive lymphatics from all the pelvic viscera, from the deeper parts of the perineum, including the membranous and cavernous portions of the urethra, and from the buttock and back of the thigh. The internal iliac lymph nodes also drain the superior half of the rectum, above the pectinate line.{{cite web|title=Ano-Rectal Anatomy|url=http://fitsweb.uchc.edu/student/selectives/Luzietti/Painful_anus_anorectal_anatomy.htm|website=University of Connecticut Health Center|access-date=18 October 2014|archive-date=3 November 2014|archive-url=https://web.archive.org/web/20141103122745/http://fitsweb.uchc.edu/student/selectives/Luzietti/Painful_anus_anorectal_anatomy.htm|url-status=dead}}{{cite book|last1=MD|first1=Tao Le, MD, MHS, Vikas Bhushan, MD, Matthew Sochat, MD, Max Petersen, Goran Micevic, Kimberly Kallianos|title=First Aid for the USMLE Step 1 2014 : A Student-to-Student Guide|date=2014|isbn=978-0071831420}}
