What is a Dermatome?
The term “dermatome” refers to a tissue that covers the spinal cord. Dermatomes help physicians to build maps of the spinal cord, which help in diagnosing. Two major maps are recognized by medical experts. There is the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still often employed. The trigeminal and maxillary nerve are the largest dermatomes.
Dermatomes are areas of skin which are connected to a specific nerve bundle. In the case of spinal cord injury, the pain could be felt in a dermatome, which is innervated by that nerve. Similarly, the pain caused by an outbreak of shingles is felt by specific spinal nerves. If you are experiencing pain or neurological condition involving the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by a single spinal nerve. These nerves carry motor, sensory and autonomic information. They form part of the peripheral nerve system which connects the brain and rest of the body. Dermatomes can become affected due to a spinal cord lesion. When one of these dermatomes becomes injured, it could be easily treated using local anesthetic.
Dermatomes in the thoracic region are labeled using letter-number sequences that demonstrate the connection between the area as well as the nerve that is responsible for this area. For example C1 spinal nerve does not possess a dermatome, however those spinal nerves that are labeled C1-C8 T9, which corresponds with the belly button. Dermatomes are layered horizontally on the trunk, and dermatomes located that are located on the extremities are generally longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks that cover anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. Its name isn’t consistent and certain textbooks have distinct maps on different pages. This is especially problematic when the authors of several chapters disagree on the choice of dermatome map. Many textbooks use the maps of Foerster, Keegan, and Garrett but don’t include adequate references. Moreover, four textbooks use maps with no citations. This includes one that only cites secondary sources.
The dermatome is the area of skin that receives sensory stimulation from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip less inferiorly than horizontally. This is a natural variation and certain tissues may be covered by multiple dermatomes. Additionally dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons that originate from the dorsal parts of the limbs.
