Acroposthion

Acroposthion or akroposthion is a word derived from Greek. It is the term used to describe the part of the foreskin that hangs beyond the glans penis.

Frederick Mansfield Hodges, D. Phil., (2001) describes the acroposthion:

As would be expected in a culture that valued the prepuce, the Greek language reflected this esteem through precise terminology. The Greeks understood the prepuce to be composed of two distinct structures: the posthe (ποσθη) and the akroposthion (ακροπσθτου). Posthe designates that part of the prepuce that covers the glans penis, but Greek writers occasionally used this word (or any of its variations, such as ποσθιη or ποσθια) in a general sense to designate the entire prepuce or, by extension, the entire penis. Akroposthion (or any of its alternative forms, such as ακροποσθια and ακροποσθιη) designates the tapered, tubular, visually defining portion of the prepuce that extends beyond the glans and terminates at the preputial orifice. When we speak of the iconographic representation of the long prepuce, we are really speaking of the long akroposthion for the posthe can never be larger than the unchanging surface area of the underlying glans penis.

The ridged band of highly innervated tissue is found inside the acroposthion. Winkelmann (1959) classified the foreskin, which includes the acroposthion, as specific erogenous tissue.
