[3] They are at the highest density around the fingernails where they act in monitoring slippage of objects along the surface of the skin, allowing modulation of grip on an object[citation needed]. Ruffini endings detect stretch, deformation within joints, and warmth. Features of Ruffini corpuscles. Which of the following is found in the hair follicle? This corpuscle is a type of nerve ending in the skin that is responsible for sensitivity to light touch.In particular, they have their highest sensitivity (lowest threshold) when sensing vibrations between 10 and 50 hertz. The key ultrastructural characteristic is the encircling of collagen bundles by axons and associated Schwann and connective tissue cells. The next mechanoreceptor is called Pacinian's Corpuscle. They contain an unmyelinated nerve ending surrounded by Schwann cells. The entire corpuscle is wrapped by a layer of connective tissue.
