Merkel Cells

Merkel cells are skin cells that mediate the light touch response and tactile acuity in mammals. They are concentrated in touch sensitive areas of the skin and mucosal tissues, (such as palms, fingertips, lips, soles, paw pads and mouse whiskers), and together with the low-threshold sensory neurons innervating the epidermis, serve as the mechanosensitive touch transducers of skin producing tactile discernment.
