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.<ref>{{cite book |last=Mountcastle |first=Vernon C. |year=2005 |title=The Sensory Hand: Neural Mechanisms of Somatic Sensation |publisher=Harvard University Press |page=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.
 
 
Ruffini 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.<ref>{{cite book |last=Hamilton |first=Nancy |year=2008 |title=Kinesiology: Scientific Basis of Human Motion |publisher=McGraw-Hill |pages=76–7}}</ref>
