What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of the spine. Dermatomes help physicians to build images of spinal cord that help in diagnosing. Two major maps are recognized by medical experts. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are frequently employed. The trigeminal nerve and the maxillary nerve are the largest dermatomes.
Dermatomes are skin-like areas that connect to a specific nerve. When there is a spinal cord injuries, pain may be felt in a dermatome, which is controlled by the nerve. The same is true for the pain caused by shingles outbreaks can be felt in specific spinal nerves. If you suffer from nerve pain or neurological problem affecting the dermatome, it is recommended that you see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin supplied by the spinal nerve. These nerves provide motor, sensory and autonomic messages. They form an element of the peripheral nervous system, which connects brain and all the body. Dermatomes can be affected by a spinal cord lesion. If one of these gets injured, it is able to be easily treated using local anesthetic.
Dermatomes in the thoracic region are identified by letter-number combinations, which show the connection between the region along with the sensor nerve that serves that area. For example C1 spinal nerve doesn’t possess a dermatome, however those spinal nerves that are labeled C1 – C8, while T9 corresponds with the belly button. Dermatomes are layered in horizontally on the trunk, while dermatomes on the extremities tend to be long.
Dermatome Map
Dermatome maps are the most common element in textbooks that cover anatomy. The dermatome map is inconsistent both intra and inter-textbook. The name is not consistent as are some textbooks that have different maps on various pages. This can be particularly challenging when the authors of different chapters differ in their choice of dermatome maps. Many textbooks use the diagrams drawn by Foerster, Keegan, and Garrett but do not include appropriate references. Additionally, four textbooks employ maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the regions of the skin that receives sensory information from the dorsal branch of one spinal nerve. The dermatomes are not uniformly placed, however they tend to dip more inferiorly than horizontally. This is a normal variation and some tissues may be covered by multiple dermatomes. Additionally dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons of those limbs that are dorsal.
