The ridged band is a band of highly innervated wrinkly skin toward the end of the foreskin. The term ridged is used to describe the area instead of the more commonly used term "wrinkled". It has, especially in regard to phimosis (and preputioplasty), been called a preputial ring or phimotic ring. Ring being analogous to 'band', referring to the shape, and preputial meaning pertaining to the prepuce. More particularly it refers to the "transitional area from the external to the internal surface of the prepuce," or foreskin. John R. Taylor, MB, a Canadian pathologist and medical researcher, first used the term "ridged band" instead of "wrinkly skin" and described the ridged band at the ''Second International Symposium on Circumcision'', organized by (NOCIRC ) (an organisation opposing infant circumcision) in San Francisco, 1991, after examining the foreskins of 22 adults obtained at autopsy.〔 The mean age was 37 years, range 22-58.〔 The prepuces were studied grossly and histologically.〔 The term "ridged band" was subsequently used by Taylor in an anatomical and histological study of the foreskin published in the ''British Journal of Urology'' in 1996.〔 (Reprint: cirp.org)〕 Most or all of the ridged band is removed by male circumcision.〔 ==Structure== Taylor described a transversely ridged band of mucosal tissue located just inside the tip of the foreskin near the mucocutaneous boundary known as ''preputial sphincter''. He characterized this ridged band as "intensely vascular". He described the band as "richly innervated", stated that it "contains more Meissner's corpuscles than does the smooth mucosa", and noted that these tactile corpuscles were found only in the crests of ridges. This structure is generally part of the tissue that is removed in circumcisions. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ridged band」の詳細全文を読む スポンサード リンク
