**'''Tunica Dartos''' - Smooth muscle layer found below the skin of the scrotum. Smooth muscle tone controlled by Androgens released in response to temperature changes detected by sensory nerves within the scrotal skin. The tunica dartos is responsible for holding the testes close to the body during cold temperatures as it can maintain sustained contraction.
