Some referred pain due to visceral sensations refer to dermatomes that send fibers to the same level of spinal cord. A dermatome is an area of skin supplied by sensory neurons that arise from a spinal nerve ganglion. Symptoms that follow a dermatome (e.g. like pain or a rash) may indicate a pathology that involves the related nerve root ...
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]

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 ...

Chicken pox appears nearly everywhere on the body, but herpes zoster tends to follow one or two dermatomes; for example, the eruptions may appear along the bra line, on either or both sides of the patient. [citation needed]
Dysfunction of the superior cluneal nerves lead to many different neuropathic symptoms such as burning pain, numbness, tingling, and dysesthesia around the low back and upper gluteal area. The most common symptoms are localized unilateral low back pain, though up to anywhere between 40 and 82% of patients may complain of leg symptoms – pain ...
