Web1 aug. 2024 · Meissner’s corpuscles are one type of mechanoreceptor located within the papillary dermis layer of the skin that plays an important role in the sense of touch. These structures exist within dermal papillae of glabrous skin and range in size from 80 to 150 µm in length to 20–40 µm in diameter ( Vega et al., 2012 ). Tactile corpuscles or Meissner's corpuscles are a type of mechanoreceptor discovered by anatomist Georg Meissner (1829–1905) and Rudolf Wagner.

WebMeissner's corpuscles, also known as tactile corpuscles, are found in the upper dermis, but they project into the epidermis. They are found primarily in the glabrous skin on the fingertips and eyelids. They respond to fine touch and pressure, but they also respond to low-frequency vibration or flutter. WebCutaneous mechanoreceptors can be categorized by morphology, by what kind of sensation they perceive, and by the rate of adaptation. Furthermore, each has a different receptive field. The Slowly Adapting type 1 (SA1) mechanoreceptor, with the Merkel corpuscle end-organ, underlies the perception of form and roughness on the skin. [1]
