What is the first branch of the Anterior Division of Internal Iliac?
Umbilical Artery.
What gives rise to the superior vesical artery ?
Umbilical artery.
What is the third branch of the anterior division of internal iliac

Obturator artery.
What is the smaller of terminal branch of the anterior division ?
Internal Pudendal.
What is the second Terminal branch of the anterior division
Inferior Gluteal.
What is the 4th branch of the anterior division ?
Middle Rectal.
What does the Inferior vesical and middle rectal arteries supply in males ?
Prostate gland, Seminal vesicles and Ductus deferens.
Where do the testicular and ovarian arteries originate from ?
both originate from abdominal aorta @ L2 due to the positioning of the organs during development.
What us the additional branch in females that arises before the umbilical artery in the anterior division ?

What are the three branches of the posterior division ?
Iliolumbar, lateral sacral and superior gluteal.
What does the Umbilical artery supply ?
Urinary Bladder and Ureter.

What does the Obturator artery give overall blood supply too ?
The muscles of the pelvis, the medial compartment of the thigh and the hip joint.
Where does the Internal pudendal artery leave the pelvis.
The greater sciatic foramen beside the piriformis.
