Somatosensory Phasic vs. Tonic Receptors * Phasic receptors- receptors that adapt quickly to stimuli meaning that they initially fire in the presence of a stimulus and then stop are particularly effective at conveying information about changes in a stimulus (dynamic info). * Tonic receptors- receptors that slowly adapt convey information about the persistence of a stimulus (static info.) Skin Receptors The two principal mechanoreceptors in the superficial layers of the skin are the * Meissner’s corpuscle- * rapidly adapting receptor , coupled mechanically to the edge of the papillary ridge, a relationship that confers fine mechanical sensitivity. * Merkel disk receptor * encloses a semirigid structure that transmits compressing strain from the skin to the sensory nerve ending, evoking sustained, slowly adapting response Skin Receptors * The two mechanoreceptors found in the deep subcutaneous tissue are the * Pacinian corpuscle * The Pacinian corpuscle responds to rapid indentation of the skin
