Which artery courses along the testicular periphery and is the source for centripetal arteries?

• A. Capsular Artery
• B. Centripetal Arteries
• C. Deferential Artery
• D. Cremasteric Artery

Answer: (A)

The testicular arterial supply runs from the outside toward the inside. The capsular arteries travel along the outer surface of the testis, just beneath the tunica albuginea, forming the peripheral vascular ring. From these surface branches, centripetal arteries radiate inward through the parenchyma toward the mediastinum to supply the inner tissue. So the artery that courses around the testicular periphery and serves as the source for centripetal arteries is the capsular artery. The other vessels have different roles and locations—deferential supplies the vas deferens, and cremasteric runs with the cremaster muscle—so they don’t fit this description.
