Two-point discrimination (2PD) is the ability to discern that two nearby objects touching the skin are truly two distinct points, not one. It is often tested with two sharp points during a neurological examination [ 1 ] : 632 [ 2 ] : 71 and is assumed to reflect how finely innervated an area of skin is.
Two-point discrimination (2PD) is a neurological examination in which two sharp points are applied to the surface of a part of the body in order to see if the patient recognizes them as two discrete sensations. [2] The two-point threshold is the smallest distance between the two points that the patient can recognize. [17]
The two ascending tracts meet at the level of the sixth thoracic vertebra (T6). Ascending tracts typically have three levels of neurons, namely first-order, second-order, and third-order neurons, that relay information from the physical point of reception to the actual point of interpretation in the brain. Neural connections in the DCML pathway.
It can determine how short a distance between two impressions on the skin can be distinguished. To differentiate between two points and one point of equal area (the sum of the areas of the two points equals the area of the third point), Dr. Sidney Weinstein created the three-point esthesiometer.
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] The main functions of the somatosensory system are the perception of external stimuli, the perception of internal stimuli, and the regulation of body position and balance ...

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 ...
