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.

Rice 15 September Tactile corpuscles or Meissner’s corpuscles ; discovered by dr Georg Meissner — and Rudolf Wagner [1] are a type of mechanoreceptor. The Journal of Neuroscience.

Tactile corpuscle

Side view of a papilla of the hand. 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. Free nerve ending Nociceptors.

Also, tactile corpuscles do not detect noxious stimuli ; this is signaled exclusively by free nerve endings. The rate at which they are lost correlates well with the age-related loss in touch sensitivity for small probes. Golgi organ Muscle spindle Intrafusal muscle fiber Nuclear chain fiber Nuclear bag fiber.

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.
