Changes

The [[foreskin]] and the [[glans]] have similar functions. Both are designed to trigger nerve impulses that lead to [[erection]] and ejaculation. The [[glans ]] detects deep pressure and movement. The [[foreskin ]] detects movement through the accordion-like action of the [[ridged band]]; in addition, the outer, true [[skin]] of the foreskin has an exquisite ability to detect light touch and pin-prick. The glans lacks these abilities because it relies on the covering foreskin to provide them.
