Ruffini Endings are one of the four main cutaneous mechanoreceptors. Named after Angelo Ruffini, they are slowly adapting receptors found in the dermis and subcutaneous tissue of the skin. These thin cigar-shaped encapsulated sensory endings measure pressure when the skin is stretched.Their main function is thermoreception, as they repond to heat.
The other specialised skin-thermoreceptor is the Krause corpuscle, which responds to cold.
