Also, tactile corpuscles do not detect noxious stimuli ; this is signaled exclusively by free nerve endings. They are most concentrated in thick hairless skin, especially at the finger pads.

This page was last edited on 27 Decemberat This section does not cite any sources. Feelings of deep pressure from a poke, for instance are generated from lamellar corpuscles the only other type of phasic tactile mechanoreceptorwhich are located deeper in the dermis, and some free nerve endings.
Anatomical terms of microanatomy [ edit on Wikidata ]. Tactile corpuscles or Meissner’s corpuscles ; discovered by anatomist Georg Meissner — and Rudolf Wagner  are a type of mechanoreceptor. Since they are rapidly adapting or phasicthe action potentials generated quickly decrease and eventually cease this is the reason one stops “feeling” one’s clothes. Retrieved 30 January The number of tactile corpuscles per square millimeter of human skin on the fingertips drops fourfold [ clarification needed ] between the ages of 12 and Its two nerve fibers axons running with spiral coils around the tactile corpuscle.
Because of their superficial location in the dermisthese corpuscles are particularly sensitive to touch and vibrations, but for the same reasons, they are limited in their detection because they can only signal that something is touching the skin.
In particular, they have their highest sensitivity lowest threshold when sensing vibrations between 10 and 50 Hertz. The Journal of Neuroscience.
They are sensitive to shape and textural changes in exploratory and discriminatory touch. The rate at which they are lost correlates well with the age-related loss in touch sensitivity for small probes. Apparent termination of one of these fibers. Retrieved 7 May Their Nerve Supply and Significance”.
The Anatomical Record Part A: Tactile corpuscles are encapsulated unmyelinated nerve endings, which consist of flattened supportive cells arranged as horizontal lamellae surrounded by a connective tissue capsule. Rice 15 September Views Read Edit View history.
