Ruffini ending

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. It is believed to be useful for monitoring slippage of objects along the surface of the skin, allowing modulation of grip on an object.
