  Mucocutaneous zone - Wikipedia, the free encyclopedia
A mucocutaneous zone is a region of skin comprising both mucosa and cutaneous skin.
A mucocutaneous zone is found at the lips, the conjunctival region, at the tip of the penis (notably the glans penis and ridged band), the vulva, the perianal zone, and similar locations.
Winkelmann reported the mucocutaneous boundary is a "specific erogenous zone with rete ridges where the nerve endings rise closer to the surface."

 Ridged band - Wikipedia, the free encyclopedia
Winkelmann (1959) suggested that the boundary between the outer skin of the penis and the inner mucosa (the mucocutaneous boundary) is a specific erogenous zone [3].
This band of tissue, which he called the ridged band, contains nerve endings called Meissner's corpuscles These nerve endings are arranged at the crest of rete ridges and, like the nipples and the soles of the feet, are sensitive to light touch and specifically stroking and fluttering sensations.
The specific type of erogenous zone found is found in the mucocutaneous regions of the body.

The boundary between the epithelium and lamina propria is quite distinct and is uneven due to numerous connective tissue papillae.
In contrast, the boundary between the mucosa and submucosa is marked by the muscularis mucosae, which is the deepest layer of the mucosa.

Defects in the genes encoding keratins 6a and 16 were found to underlie PC-1, whereas defects in keratins 6b and 17 were shown to cause PC-2.
To date, more than 80 mutations in these four keratin genes have been identified in PC families, the vast majority of which occur within the helix boundary motifs that flank the central -helical rod domain.
Mucocutaneous examination showed the presence of median rhomboid glossitis.

 THE MERCK MANUAL, Sec. 3, Ch. 35, Anorectal Disorders
The anal canal and adjacent external skin are generously supplied with somatic sensory nerves and are highly susceptible to painful stimuli; the rectal mucosa has an autonomic nerve supply and is relatively insensitive to pain.
At the superior boundary of the anal canal is the anorectal junction (pectinate line, mucocutaneous junction, dentate line), where there are 8 to 12 anal crypts and 5 to 8 papillae.
Anorectal abscesses and fistulas originate in relation to the crypts.

 Ridged band
The ridged band contains Meissner's corpuscles which are fine-touch receptors.
Taylor's work built upon earlier work, including that of R. Winkelmann, a dermatologist who in 1959 discussed the structure of the foreskin and other mucocutaneous zones.[1].

The various mucocutaneous boundaries are the sites of acute sensation in humans and have an important role in sexual arousal and sexual response.
Taylor reported that the prepuce is richly vascularized and innervated with sensitive Meissner’s corpuscles (nerve endings) in discrete ridges, which are arranged in a ridged band that encircles the inner surface of the preputial opening near the mucocutaneous boundary of the foreskin.
The part removed contains the mucocutaneous boundary and the highly innervated and vascularized ridged bands.

 Issues associated with the introduction of circumcision into a non-circumcising society
It is difficult to control complications with mass circumcisions.
Circumcision excises significant amounts of nerve bearing penile skin and mucosa, especially the ridged band structure near the mucocutaneous boundary.
The protective effects of circumcision against HIV remain controversial.

 [No title]
The prepuce is profusely innervated especially near the tip in the ridged band area where the mucocutaneous boundary occurs.
It is now understood that this junction is the most sensitive and erogenous part of the penis.17,18,29,30,32 Winkelmann explains the importance of the mucocutaneous boundary in human sexual response.18 He explains, "All biologic phenomena, including sensation, are the result of a certain statistical events.
It is logical to anticipate that some individuals will have cutaneous hyperneuria, and also to expect eventually to find some individuals with actual diminution in organization of the cutaneous nerves for sensation.

In animal cells, the cell membrane establishes this separation alone, whereas in yeast, bacteria and plants an additional cell wall forms the outermost boundary, providing primarily mechanical support.
The plasma membrane is only about 10 nm thick and may be discerned only faintly with a transmission electron microscope.
