Question

Testicular arteries originate from and supply which structures? At what vertebral level do they arise?

A) Abdominal aorta; testes and epididymis; L2
B) Renal artery; testes and vas deferens; L1
C) Inferior vena cava; testes and seminal vesicles; L3
D) Common iliac artery; testes and prostate; L4

Answer 1

Testicular arteries originate from the abdominal aorta, supply the testes and epididymis, and arise at the vertebral level L2, making option A the correct response.

Step-by-step explanation:

The testicular arteries originate from the abdominal aorta and supply blood to the testes and epididymis. These arteries arise at approximately the vertebral level of L2.

The correct answer to the student's question is A) Abdominal aorta; testes and epididymis; L2. The testicular arteries are part of the gonadal arteries, which are responsible for supplying the reproductive organs. The fact that they emerge from the abdominal aorta, a critical vessel embedded in fatty tissue behind the peritoneal cavity, is notable since this aorta gives rise to several significant branches, including the gonadal arteries, and ends around the level of vertebra L4.
