Which artery supplies blood directly to the epididymis?

• A. Capsular
• B. Testicular
• C. Cremasteric
• D. Centripetal

Answer: (C)

The correct answer is the artery that supplies blood directly to the epididymis, which is the cremasteric artery. The cremasteric artery branches off the inferior epigastric artery and plays a significant role in providing blood supply to the scrotum, including the muscles and other structures associated with the testicular region. The cremasteric artery also has important connections with the testicular artery, but its direct role in the blood supply to the epididymis is crucial. It supports the vascular network that nourishes the testes and surrounding structures, especially when movements or temperature changes occur. In contrast, while the testicular artery supplies the testes themselves and carries blood from the abdominal aorta, it does not specifically target the epididymis directly. The capsular artery primarily supplies the tunica albuginea, which is the outer fibrous layer of the testis, but is not directly responsible for the vascular supply to the epididymis. The centripetal artery is a branch of the testicular artery that supplies blood to the testes and contributes to the countercurrent exchange mechanism, but it does not directly supply the epididymis.
