==Function==

This spindle-shaped receptor is sensitive to skin stretch, and contributes to the kinesthetic sense of and control of finger position and movement.<ref>{{CiteCita booklibro|lastcognome=Mountcastle |firstnome=Vernon C. |yearanno=2005 |titletitolo=The Sensory Hand: Neural Mechanisms of Somatic Sensation |publishereditore=Harvard University Press |pagep=34}}</ref> It is believed to be useful for monitoring slippage of objects along the surface of the skin, allowing modulation of grip on an object.

Ruffinian endings are located in the deep layers of the skin, and register mechanical deformation within joints, more specifically angle change, with a specificity of up to 2 degrees, as well as continuous pressure states.They also act as a thermoreceptors that respond for a long time, so in case of deep burn there will be no pain as these receptors will be burned off. <ref>{{CiteCita booklibro|lastcognome=Hamilton |firstnome=Nancy |yearanno=2008 |titletitolo=Kinesiology: Scientific Basis of Human Motion |publishereditore=McGraw-Hill |pagespp=76–7}}</ref>
