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.

Tactile corpuscles are encapsulated unmyelinated nerve endings, which consist of flattened supportive cells arranged as horizontal lamellae surrounded by a connective tissue capsule. Retrieved from ” https: In particular, they have their highest sensitivity lowest threshold when sensing vibrations between 10 and 50 Hertz.
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. Tactile corpuscles or Meissner’s corpuscles ; discovered by anatomist Georg Meissner — and Rudolf Corpuxculos  are a type of mechanoreceptor.

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 rapidly adapting mechanoreceptors. A tactile papilla seen from above so as to show its transverse cirpusculos. Also, tactile corpuscles do not detect noxious stimuli ; this is signaled exclusively by free nerve endings.
