}}</ref> The foreskin is attached to the [[glans penis]] on the ventral side by the [[frenulum]], which usually limits [[Retraction of the foreskin| retraction]] to a widely variable degree. The [[ridged band]] emanates from the frenulum.<ref name="cold-taylor1999" />
The epithelium of the outer layer of the foreskin is true [[skin]] while the epithelium of the inner layer is [[Preputial mucosa|mucosal membrane]]. There is a mucocutaneous boundary at the tip of the foreskin. The mucocutaneous junction is a specific erogenous zone.<ref name="winklemann1959">{{REFjournal |last=Winkelmann |init=RK |author-link= |title=The erogenous zones: their nerve supply and significance |journal=Mayo Clin Proc |date=WinkelmannRK 1959-01-21 |volume=34 |issue=3 |pages=39-47 |url=http://www.cirp.org/library/anatomy/winkelmann/ |quote= |pubmedID=13645790 |pubmedCID= |DOI= |accessdate=2019-10-14}}</ref> Taylor et al. reported:
<blockquote>
The vascular ridges of the `ridged band' and its [[Meissner's corpuscles]] firmly separate preputial epithelium from true [[skin]] and place preputial [[mucosa]] amongst other mucocutaneous [[mucosa]]e. Winkelmann emphasized the structural and functional importance of junctional regions of the body and focused on mucocutaneous end-organs, or `genital corpuscles', of the glans penis and prepuce. Some of these end-organs resemble Krause end-bulbs; others resemble [[Meissner's corpuscles]]. … [[Meissner's corpuscles]] of the prepuce may be compared with similar nerve-endings in the finger-tips and lips, which respond in a fraction of a second to contact with light objects that bring about deformation of their capsules. … The prepuce provides a large and important platform for several nerves and nerve endings. The innervation of the outer [[skin]] of the prepuce is impressive; its sensitivity to light touch and pain are similar to that of the [[skin]] of the penis as a whole.<ref name="taylor1996" />
