||
− | 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> |
