  2. Tactile corpuscle - Wikipedia

    en.wikipedia.org/wiki/Tactile_corpuscle

    Tactile corpuscles or Meissner's corpuscles are a type of mechanoreceptor discovered by anatomist Georg Meissner (1829–1905) and Rudolf Wagner. [ 1 ] [ 2 ] This corpuscle is a type of nerve ending in the skin that is responsible for sensitivity to pressure .

  3. Merkel cell - Wikipedia

    en.wikipedia.org/wiki/Merkel_cell

    Merkel cells, also known as Merkel–Ranvier cells or tactile epithelial cells, are oval-shaped mechanoreceptors essential for light touch sensation and found in the skin of vertebrates. They are abundant in highly sensitive skin like that of the fingertips in humans , and make synaptic contacts with somatosensory afferent nerve fibers .

  4. Sensory nervous system - Wikipedia

    en.wikipedia.org/wiki/Sensory_nervous_system

    The end-bulb of Krause or bulboid corpuscle detects temperatures above body temperature. Ruffini's end organ detects temperatures below body temperature. TRPV1 is a heat-activated channel that acts as a small heat detecting thermometer in the membrane which begins the polarization of the neural fiber when exposed to changes in temperature.

  5. Mechanoreceptor - Wikipedia

    en.wikipedia.org/wiki/Mechanoreceptor

    The Pacinian corpuscle or Vater-Pacinian corpuscles or Lamellar corpuscles [5] in the skin and fascia detect rapid vibrations of about 200–300 Hz. [3] [6] They also produce transient responses, but have large receptive fields. Free nerve endings detect touch, pressure, stretching, as well as the tickle and itch sensations. Itch sensations are ...

  6. Somatosensory system - Wikipedia

    en.wikipedia.org/wiki/Somatosensory_system

    This photo shows tactile markings identifying stairs for visually impaired people. The somatosensory system , or somatic sensory system is a subset of the sensory nervous system . It has two subdivisions, one for the detection of mechanosensory information related to touch, and the other for the nociception detection of pain and temperature. [ 1 ]

  7. Tactile discrimination - Wikipedia

    en.wikipedia.org/wiki/Tactile_discrimination

    Stereognosis (Tactile Gnosis) is defined as the ability to tell the difference and identify objects via touch in the absence of visual or auditory contact. The subject will need to be able to recognize temperature, spatial properties, texture, and size to reach an accurate conclusion to what the object is. [ 13 ]

  8. Cutaneous receptor - Wikipedia

    en.wikipedia.org/wiki/Cutaneous_receptor

    Cutaneous receptors are at the ends of afferent neurons. works within the capsule. Ion channels are situated near these networks. In sensory transduction, the afferent nerves transmit through a series of synapses in the central nervous system, first in the spinal cord, the ventrobasal portion of the thalamus, and then on to the somatosensory cortex.

  9. Merkel nerve ending - Wikipedia

    en.wikipedia.org/wiki/Merkel_nerve_ending

    Merkel nerve endings (also Merkel's disks, [1] or Merkel tactile endings [2]) are mechanoreceptors situated in the basal epidermis as well as around the apical ends or some hair follicles. [2] They are slowly adapting. They have small receptive fields measuring some milimeters in diameter. Most are associated with fast-conducting large ...
