Primate glabrous-skin encapsulated mechanoreceptors {Meissner's corpuscle} {Meissner corpuscle} are fast-adapting, have small receptive fields of 100 to 300 micrometers diameter, and lie in rows just below fingertip surface-ridge dermal papillae. Meissner's corpuscles are only in primates and correspond to Krause end bulbs in other mammals.
Meissner's corpuscles respond to vibration, to detect changing stimuli. Maximum sensitivity is at 20 to 40 Hz. Range is from 1 Hz to 400 Hz. Meissner's corpuscles send to myelinated dorsal-root neuron fibers.
