The Haarscheibe.
The Haarscheibe is a specialized spot of epidermis containing many Merkel cell-neurite complexes. It is a highly sensitive, slowly adapting, modality-specific touch receptor occurring in all mammals. Its exact role in signaling sensation in human beings is undetermined, and the function of Merkel cells, with their distinctive cytoplasmic granules, in transducing mechanical force into neural action potentials remains to be determined.
