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 .
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 ...
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 .
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 ...
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.
A free nerve ending (FNE) or bare nerve ending, is an unspecialized, afferent nerve fiber sending its signal to a sensory neuron. Afferent in this case means bringing information from the body's periphery toward the brain.
Group Aβ of the type II sensory fiber is a type of sensory fiber, the second of the two main groups of touch receptors.The responses of different type Aβ fibers to these stimuli can be subdivided based on their adaptation properties, traditionally into rapidly adapting (RA) or slowly adapting (SA) neurons. [1]
' pain receptor ') is a sensory neuron that responds to damaging or potentially damaging stimuli by sending "possible threat" signals [1] [2] [3] to the spinal cord and the brain. The brain creates the sensation of pain to direct attention to the body part, so the threat can be mitigated; this process is called nociception .
