Web10 jan. 2024 · Meissner corpuscles consist of an axon, nonmyelinating glial cells (denominated laminar cells regarded as modified and specialized Schwann cells), and a capsule of fibroblasts of endoneurial origin ( Figure 3 and Figure 4) [ 10, 12 ]. The axon is usually unique, although, occasionally, one or two accessory axons can be found.
Web16 dec. 2024 · We instead propose that lamellar cells play an active role in shaping the rapid adaptation of afferent firing, a process that endows Pacinian and Meissner corpuscles with exquisite sensitivity to transient pressure and vibration.

Sensory neurons with a higher density of Meissner's corpuscles will …
Tactile corpuscles or Meissner's corpuscles are a type of mechanoreceptor discovered by anatomist Georg Meissner (1829–1905) and Rudolf Wagner. This corpuscle is a type of nerve ending in the skin that is responsible for sensitivity to pressure. In particular, they have their highest sensitivity (lowest threshold) when sensing vibrations between 10 and 50 hertz. They are rapidly adaptive receptors. They are most concentrated in thick hairless skin, especially at the finger pa… WebIn glabrous (hairless) skin, there are four principal types of mechanoreceptors, each shaped according to its function (Fig.2.3.1).
