Celiac Superior mesenteric Renal Ovarian Common iliac Inferior mesenteric Superior rectal Testicular Ext. iliac Int. iliac Inguinal ligament Median Sacral Femoral Rules: 1. All pelvic organs are supplied by branches of the internal iliac artery except the ovaries and the upper third of the rectum. 2. Venous drainage follows the arterial supply, including the portal tributary, the inferior mesenteric vein. 3. Portal caval anastomses are found at the inferior rectal veins. 6. Identify the lymphatic drainage of structures of the pelvis and perienum. Rules: Para-aortic • External iliac • Superficial Inguinal Internal iliac Lymphatics drain toward lymph nodes along internal iliac veins, except for the ovary (para-aortic nodes), and superior portion of the rectum (inferior mesenteric nodes) Perineum drains to superficial inguinal nodes 7. Follow the course taken by an ovum through the female reproductive tract and the pathway taken by a spermatozoon through the male reproductive tract.
