Discoveries in Molecular, Cellular, and Evolutionary Biology. Tactile corpuscles are rapidly adapting mechanoreceptors. 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.

The Anatomical Record Part A: Tactile corpuscuoos or Meissner’s corpuscles ; discovered by anatomist Georg Meissner — and Rudolf Wagner [1] are a type of mechanoreceptor. Retrieved 30 January Views Read Edit View history. By using this site, you agree to the Terms of Use and Privacy Policy. Retrieved from ” https: They are most concentrated in thick hairless skin, especially at the finger pads.

Their acute sensitivity provides the neural basis for reading Braille text.

Please help improve this section by adding citations to reliable sources. They are distributed on various areas of the skinbut concentrated in areas especially sensitive to light touch, such as the fingers and lips.

Their Nerve Supply and Significance”. Tactile corpuscle Papilla of the hand, magnified times. The rate at which they are lost correlates well with the age-related loss in touch sensitivity for small probes. 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.

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.

In particular, they have their highest sensitivity lowest threshold when sensing vibrations between 10 and 50 Hertz. Unsourced material may be challenged and removed.

Any corpsculos deformation of the corpuscle will cause sodium ions to enter it, creating an action potential in the corpuscle’s nerve fiber. Also, tactile corpuscles do not detect noxious stimuli ; this is signaled exclusively by free nerve endings.

Tactile corpuscles are encapsulated unmyelinated nerve endings, which consist of flattened supportive cells arranged as horizontal lamellae meissnr by a connective tissue capsule. Rice 15 September Retrieved 7 May Papilla of the hand, magnified times. The Journal of Neuroscience. 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.
