|trans-title=About the nerve end apparatuses in the human [[skin]]

The two primary sensory receptors in primate [[skin ]] are free nerve endings and encapsulated or corpuscular receptors. While free nerve endings (pain, itch, and temperature receptors) are found in most [[skin]], the encapsulated receptors are concentrated in regions that require specialised touch sensitivity, such as at the fingertips, lips, external genitalia, perianal [[skin]], and transition areas between [[skin ]] and mucous membranes.<ref>{{REFbook

Distributed on various areas of the [[skin]], but concentrated in areas especially sensitive to light touch, such as the fingers, lips, nipples and foreskin.<ref>{{REFjournal
