}}</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 mucosae. 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" /> </blockquote>
The layer of [[dartos]] muscle is contained within the foreskin.<ref name="cold-taylor1999 /> The dartos muscle keeps the foreskin snugly against the glans. The fibers of the dartos muscle form a whorl at the tip that functions as a sphincter. The sphincter opens to allow urine to flow out, but closes to protect the penis from foreign matter, contaminants, and pathogens.<ref name="lakshmanan-prakash1980"/><ref>{{REFjournal
