The dermatomes are controlled by nerves associated with specific cervical openings in the cervical spine.
The dermatome distribution provides a means for sensing a particular nerve and this will indicate the portion of the cervical spine where the lesions are and will assist the clinician in caring for the injury.
The sensitivity of the patient in sensing the various temperatures of the probes is recorded and also the areas of the patient's hands and forearm is recorded in the diagnosis.

 Patent 6447802
Similarly, nociceptive input from termini lying in a given area of skin can often be "felt" or experienced in a similar locus on the contralateral side of the animal, particularly within the same dermatome.
Due to the dermatomal summation within the spinal column, this attenuation of dermal nociceptive input is realized as an overall reduction in afferent input at the level of a given dermatome.
Generally speaking, for interfering with dermatomic summation of signals, the area of skin within a given dermatome to which the composition is applied corresponds to the degree to which summation within the spinal column is affected.
