A dermatome is an area of skin that is mainly supplied by a single spinal nerve. Each of these nerves relays sensation including pain from a particular region of skin to the brain. A dermatome also refers to the part of an embryonic somite.
Along the thorax and abdomen the dermatomes are like a stack of discs forming a human, each supplied by a different spinal nerve.
Along the arms and the legs, the pattern is different: Although the general pattern is similar in all people, the precise areas of innervation are as unique to an individual as fingerprints. A similar area innervated by peripheral nerves is called a peripheral nerve field. A dermatome is an area of skin supplied by sensory neurons that arise from a spinal nerve ganglion.
Symptoms that follow a lumbarrs e. Examples include somatic dysfunction of the spine or viral infection. Referred pain usually involves a specific, “referred” location so is not associated with a dermatome. Dfrmatomas skin problems tend to orient the lesions in the dermatomal direction. Viruses that lie dormant in nerve ganglia e.
However, the symptoms may not appear across the entire dermatome. Following is a list of spinal nerves and points that are characteristically belonging to the dermatome of each nerve: Following is a list of sensory cranial nerves:.
