Give FeedbackTHE SCROTUM
The scrotum is a thin pouch of skin, muscles, and fascia that contains and supports the testes, the epididymides, and parts of the spermatic cords. The smooth-muscle layer of the scrotum that is covered by a thin layer of skin disposed in folds or rugae is called the dartos muscle. It contracts reflexly with the cord to raise the testes closer to body warmth. The tissues of the scrotum are continuous with those of the groin and perineum.
