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. In clinical settings, two-point discrimination ...
Tactile discrimination is the ability to differentiate information through the sense of touch. The somatosensory system is the nervous system pathway that is responsible for this essential survival ability used in adaptation. [1] There are various types of tactile discrimination. One of the most well known and most researched is two-point ...
The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway (PCML) is the major sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.
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 myelinated ...
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] The main functions of the somatosensory system are the perception of external ...
The Lions had plenty of issues besides that 2-point play Saturday. Derrick Barnes whiffed on a would-be safety that led to Lamb’s long TD, Goff threw two interceptions, including one late in the ...
The sensory decussation or decussation of the lemnisci is a decussation (a crossing over) of axons from the gracile nucleus and cuneate nucleus, known together as the dorsal column nuclei. The dorsal column nuclei are responsible for fine touch, vibration, proprioception and two-point discrimination. The fibers of this decussation are called ...
The 2-point try's failure added an additional obstacle in New York's quest to overcome the 14-point fourth-quarter deficit it faced against Pittsburgh. Still, the Giants still had a chance to ...
