Web6 mrt. 2024 · Meissner corpuscles are most sensitive to low-frequency vibrations between 10 to 50 Hertz and can respond to skin indentations of less than 10 micrometers. … WebMeissner's corpuscles are a type of mechanoreceptor discovered by anatomist Georg Meissner (1829 – 1905) and Rudolf Wagner. [1] [2] They are a type of nerve ending in the skin that is responsible for sensitivity to light touch. In particular, they have their highest sensitivity (lowest threshold) when sensing vibrations between 10 and 50 hertz.

WebMeissners korpuskel, upptäckt av Georg Meissner och Rudolf Wagner [ 1], är en sorts känselreceptorer [ 2] som består av nervändar i huden vilka är känsliga för lätt beröring. De är som mest känsliga för vibrationer på mellan 10 och 50 hertz. Meissners korpuskel är lågtrösklig och snabbt adapterande [ förtydliga].
