Lamellated corpuscle (Pacinian) Deep pressure . corpuscle [kor´pus'l] any small mass or body. They respond to fine touch and pressure, but they also respond to low-frequency vibration or flutter. Both Merkel cells and Meissner corpuscles are primary tactile mechanoreceptors located near the upper surface of the skin. These receptors are more concentrated on the tips of the fingers, which are most sensitive to touch, especially the Meissner corpuscle (tactile corpuscle) (Figure \(\PageIndex{1}\)), which responds to light touch, and the Pacinian corpuscle (lamellated corpuscle), which responds to vibration.

The skin covering the human palm and other specialized tactile organs contains a high density of mechanosensory corpuscles tuned to detect transient pressure and vibration. Because of their superficial location in the noxious stimuli; this is signaled exclusively by free nerve endings. Medical definition of tactile cell: one of the oval nucleated cells (as in a Meissner's corpuscle) that are in close contact with the expanded ends of nerve fibers in the deeper layers of the epidermis and dermis of some parts of the body and probably serve a tactile function. This allows sodium ions to influx, creating a receptor potential. Tactile corpuscles or Meissner's corpuscles are a type of mechanoreceptor discovered by anatomist Georg Meissner (1829–1905) and Rudolf Wagner. Because of their superficial location in the dermis, these 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. e.
