Final answer:
The scrotum contains the testes, tunica dartos, and cremasteric muscle fibers, but not the bulbourethral glands.
Step-by-step explanation:
The scrotum is a part of the male reproductive system. It contains the testes, which are responsible for the production of sperm. The scrotum also contains the tunica dartos, which is a layer of smooth muscle that helps regulate the temperature of the testes. The cremasteric muscle fibers are found in the scrotum and help with the movement of the testes. However, the bulbourethral glands are not found in the scrotum, but rather in the pelvis.
