Tactile corpuscles or Meissner's corpuscles are a type of mechanoreceptor discovered by anatomist Georg Meissner (1829–1905) and Rudolf Wagner. Treasure Island (FL): StatPearls Publishing; 2020 Jan–. They contain mechanically-gated ion channels whose gates open or close in response to pressure, touch, stretching, and sound. These findings suggest that the functional integrity of axonal innervation is required for S100 protein expression by corpuscular lamellar cells[33]. ... meissner's corpuscle, meissners corpuscle.

The increased resolution is helpful in viewing the structure of a Meissner's corpuscle. After the wax cools and hardens, the tissue-containing paraffin block is sliced into thin sections by a microtome. Meissner corpuscles (MCs) in the glabrous skin of monkey digits have at least three types of innervation as revealed by immunofluorescence. corpuscle [kor´pus'l] any small mass or body. 1956 Sep;99(2):315-50. Lamellar cells may be identified with stains targeting the receptor for the vimentin and growth factor receptor TrkB. One or more axon endings would be found at the center of a surrounding sheath of supporting cells (modified Schwann … NIH These findings may underlie the age-related decrease in touch sensitivity. Tissue samples are fixed in neutral or simple formalin or Bouin solution. Hypertrophy and hyperplasia of Meissner corpuscles have been described during the initial stages of diabetes in primate studies[17]. There are four primary tactile mechanoreceptors in human skin: Merkel’s disks, Meissner’s corpuscles, Ruffini endings, and Pacinian corpuscle; two are located toward the surface of the skin and two are located deeper. Additionally, these corpuscles may detect the sensation of slip between an object and the skin, allowing for grip control. Tactile corpuscles or Meissner's corpuscles are a type of mechanoreceptor discovered by anatomist Georg Meissner (1829–1905) and Rudolf Wagner. adj., adj corpus´cular. -. The Schwann cell-derived lamellar cells have peripherally displaced nuclei and are contained within a fibroblastic capsule that is incomplete at its apex. The American journal of anatomy. Slide List.
