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]
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.

A myotome is the group of muscles that a single spinal nerve innervates. [1] Similarly a dermatome is an area of skin that a single nerve innervates with sensory fibers. Myotomes are separated by myosepta (singular: myoseptum). [2] In vertebrate embryonic development, a myotome is the part of a somite that develops into muscle.
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 ...

An area innervated by a single dorsal root is called a dermatome. Neurologists rely on maps of dermatomes and peripheral nerve fields to diagnose areas of nerve damage based on somasthetic or proprioceptive deficits in specific dermatomes and peripheral nerve fields.
