The majority of arteries of the pelvis and perineum arise from which artery?
Internal iliac artery
Which pelvic arteries do not arise from the internal iliac? Where do they arise from?
Gonadal - AA (L2)
Superior rectal - inferior mesenteric
What acronym can be used to remember branches of the posterior division of the internal iliac?
PILS
Give the branches of the posterior division of the internal iliac artery
Iliolumbar
Lateral sacral
Superior gluteal
What are the main branches of the anterior division of the internal iliac artery?
Obturator artery
Medial umbilical ligament
The medial umbilical ligament gives rise to which artery?
Superior vesical
Which pelvic artery is only found in men?
