The ridged band of prepuce is tucked just inside the tip of the unretracted prepuce; it is a richly vascular muscosal tissue heavily innervated by movement-sensitive Meissner corpuscles. In addition to touch sensitivity, the ridged band is uniquely ridged or corrugated, and not surprisingly, work in progress indicates that retraction or stetching of this accordion like structure triggers reflex contraction of bulbocavernosus and bulbospongious. These "bulb muscles" compress the root or bulb of the penis and among other things, including deep erogenous sensation, are responsible for ejaculation and clearing of residual urine from the posterior urethra following micturition.<ref name="taylor207B">{{REFjournal
