The [[frenulum]] is the structure traveling down the inner [[foreskin ]] and connects the inner foreskin to the penis between the hemispheres of the [[glans ]] below the meatus (urethral opening) at the bottom of the glans and toward the sides and proceeding down the midline of the shaft. Many of the tactile nerve endings of the [[penis]] are found in the [[frenulum]]. This is similar to the glottal frenulum attaching the tongue to the bottom of the mouth. The [[ridged bands band]] (small corrugations of tissue, like mountain "ridges") are behind the mucocutaneous juncture and when the foreskin is retracted appear behind the attachment at the sulcus. This area also contains many of the tactile nerve endings of the foreskin's neural system.

The foreskin's neural system contains hundreds of feet of nerves and thousands of tactile nerve endings, most of which are concentrated in the frenulum and frenar bandsridged band. Tactile nerves are sensuous nerves sensitive to pleasant sensations and almost all present in the penis are found within the foreskin.<ref name="taylor1996" /> Comparatively, the nerve endings found in the glans are Free Nerve Endings, or nociceptive nerve endings, which are sensitive to cold, pain and unpleasant sensations. The foreskin's vascular system is also quite complex. The blood is supplied by the frenar artery and small and larger veins are present throughout the foreskin and travel down the top of the penis. The abrupt ending of penile veins where they were crushed around the circumference of the penis just behind the area cut off can be seen on a circumcised penis. The tissue and blood vessels over the glans on the top must also be crushed prior to the dorsal cut to prevent hemorrhage and if a circumcision is to be allowed, special care must be taken to thoroughly crush the frenar artery as hemorrhage is very difficult to control.
