2. Dermatome (anatomy) - Wikipedia

   en.wikipedia.org/wiki/Dermatome_(anatomy)

   A dermatome is an area of skin that is mainly supplied by afferent nerve fibres from the dorsal root of any given spinal nerve. [ 1 ] [ 2 ] There are 8 cervical nerves (C1 being an exception with no dermatome), 12 thoracic nerves , 5 lumbar nerves and 5 sacral nerves .

3. Trigeminal nerve - Wikipedia

   en.wikipedia.org/wiki/Trigeminal_nerve

   The onion skin distribution differs from the dermatome distribution of the peripheral branches of the fifth nerve. Lesions which destroy lower areas of the spinal trigeminal nucleus (but spare higher areas) preserve pain-temperature sensation in the nose (V 1 ), upper lip (V 2 ) and mouth (V 3 ) and remove pain-temperature sensation from the ...

5. Cutaneous innervation - Wikipedia

   en.wikipedia.org/wiki/Cutaneous_innervation

   The peripheral nervous system (PNS) is divided into the somatic nervous system, the autonomic nervous system, and the enteric nervous system.However, it is the somatic nervous system, responsible for body movement and the reception of external stimuli, which allows one to understand how cutaneous innervation is made possible by the action of specific sensory fibers located on the skin, as well ...

6. Two-point discrimination - Wikipedia

   en.wikipedia.org/wiki/Two-point_discrimination

   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.

9. Cervical spinal nerve 8 - Wikipedia

   en.wikipedia.org/wiki/Cervical_spinal_nerve_8

   The C8 nerve receives sensory afferents from the C8 dermatome. This consists of all the skin on the little finger, and continuing up slightly past the wrist on the palmar and dorsal aspects of the hand and forearm. [3] Clinically, a test of the pad of the little finger is often used to assess C8 integrity. [4]
