Foreskin

The "foreskin," in a human male, is a structure composed of smooth muscle tissue, blood vessels, neurons, skin, and mucous membrane which is a part of the penis that covers and protects the glans penis and the urinary meatus. The foreskin, also known as prepuce (a term shared with the female clitoral hood). The foreskin is attached to the glans at birth and normally separates itself as a boy matures. In the western world this structure is frequently removed soon after birth in an operation called circumcision for reasons of hygiene or religious orientation.
