Gonadal arteries arise from which aspect of the aorta inferior to the renal arteries?

• A. Anterior
• B. Posterior
• C. Lateral
• D. Medial

Answer: (A)

Gonadal arteries come off the abdominal aorta from its anterior surface just below where the renal arteries originate. This ventral (anterior) location reflects how many major visceral branches arise from the front of the aorta, and these arteries then descend to reach the gonads (testes in males, ovaries in females). As they travel, they pass toward the pelvis and, in males, enter the inguinal canal as the testicular arteries; in females, they accompany the ovarian vessels to the ovaries.
