Following is a list of spinal nerves and points that are characteristically belonging to the dermatome of each nerve: [4] Dermatomes of the lower limb (modified, from Fender, after Foerster) C2 – At least one cm lateral to the occipital protuberance at the base of the skull. Alternately, a point at least 3 cm (1.2 in) behind the ear.
The dermatome is the dorsal portion of the paraxial mesoderm somite which gives rise to the skin . In the human embryo, it arises in the third week of embryogenesis . [ 2 ] It is formed when a dermomyotome (the remaining part of the somite left when the sclerotome migrates), splits to form the dermatome and the myotome. [ 2 ]

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 ...

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]
In human anatomy, cutaneous nerves are primarily responsible for providing cutaneous innervation, sensory innervation to the skin.In addition to sympathetic and autonomic afferent (sensory) fibers, most cutaneous nerves also contain sympathetic efferent (visceromotor) fibers, which innervate cutaneous blood vessels, sweat glands, and the arrector pilli muscles of hair follicles.
