Which structure’s function is to manipulate the position of the testicles in the scrotum?

• A. Cremasteric Muscle
• B. Dartos
• C. Spermatic Cord
• D. Testicular Capsule

Answer: (A)

The cremasteric muscle is responsible for moving the testicles within the scrotum. This band of skeletal muscle surrounds the spermatic cord and testis and can contract to elevate the testis toward the body, a reflex that helps position the testes for warmth and protection. The dartos muscle in the scrotal wall wrinkles the skin to regulate heat loss but does not actively move the testicle itself. The spermatic cord carries vessels, nerves, and the vas deferens, not muscles that reposition the testis. The testicular capsule (tunica albuginea) is a fibrous covering that protects the testis and does not move it.
