Prepuce of penis - e-Anatomy - IMAIOS

At the neck of glans,  the integument covering the penis leaves the surface and becomes folded upon itself to form the prepuce or foreskin.The internal layer of the prepuce is directly continuous, along the line of the neck, with the integument over the glans. Immediately behind the external urethral orifice it forms a small secondary reduplication, attached along the bottom of a depressed median raphé, which extends from the meatus to the neck; this fold is termed the frenulum of the prepuce.
