Tactile corpuscle

They are distributed on various areas of the skinbut concentrated in areas especially sensitive to light touch, such as the fingers and lips. Tactile corpuscles are encapsulated unmyelinated nerve endings, which consist of flattened supportive cells arranged as horizontal lamellae surrounded by a connective tissue capsule.

From Wikipedia, the corlusculos encyclopedia. Outer layer of the tactile re, with nuclei. They are sensitive to shape and textural changes in exploratory and discriminatory touch.

The Anatomical Record Part A: Anatomical terms of microanatomy [ edit on Wikidata ]. In corpsuculos, they have their highest sensitivity lowest threshold when sensing vibrations between 10 and 50 Hertz.

Because of their superficial location in the dermisthese corpuscles are particularly sensitive to touch and vibrations, but for the mekssner reasons, they are limited in their detection because they can only signal that something is touching the skin.

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.

If the stimulus is removed, the corpuscle regains its shape and while doing so i.

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