The Ruffini ending or Ruffini corpuscle is a class of slowly adapting mechanoreceptor thought to exist only in the glabrous dermis and subcutaneous tissue of humans. It is named after Angelo Ruffini.
Function
This spindle-shaped receptor is sensitive to skin stretch, and contributes to the kinesthetic sense of and control of finger position and movement.[1] It is believed to be useful for monitoring slippage of objects along the surface of the skin, allowing modulation of grip on an object.
