Illustration of a section through human skin, showing the location of a Meissner's corpuscle (centre right), an encapsulated nerve ending that transduces touch stimuli into electrical impulses. Meissner's corpuscles are found in upper dermis: this one is located between two folds of the upper epidermis. The skin, particularly the dermis, contains other encapuslated and free nerve endings that accommodate such stimuli as pressure, heat, cold and pain. The dermis is also rich in blood vessels; here, arterial capillaries appear red, venous blue.
