What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers your spinal cord. Dermatomes play a crucial role in allowing physicians to build images of spinal cord that aid in the diagnosis. Two major maps are recognized by medical professionals. The Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still often utilized. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.
Dermatomes are areas of skin which are connected to a particular nerve bundle. In the case of spinal cord injury, the pain could be felt in a dermatome, which is innervated by that nerve. The same is true for the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you feel discomfort or neurological issue involving the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is provided by only one spinal nerve. These nerves carry motor, sensory as well as autonomic information. They form a part of the peripheral nervous system, which connects the brain and rest of the body. Dermatomes can become affected due to a spinal cord lesion. If one of these dermatomes becomes injured, it can be treated easily with the use of a local anesthetic.
Dermatomes in the thoracic area are marked with letters-numbers that illustrate the connection between the region as well as the nerve that is responsible for that area. For example the C1 spinal nerve does not have a dermatome, but others spinal nerves have been labeled as C1-C8 T9, which corresponds to belly button. Dermatomes are layered in horizontally on the trunk however, dermatomes on the extremities are typically linear.
Dermatome Map
Dermatome maps are a common feature of textbooks teaching anatomy. However, the dermatome map is not uniform both inside and inter-textbook. Its name isn’t consistent as are some textbooks that have various maps on different pages. This is especially problematic when the authors of different chapters differ in their choice of dermatome map. Most textbooks use map of Foerster, Keegan, and Garrett but don’t include the proper references. Moreover, four textbooks use maps that do not have citations, such as one that only cites secondary sources.
The dermatome is the area of the skin that receives sensory information from the dorsal roots of one spinal nerve. The dermatomes are not uniformly situated, but they tend to dip less inferiorly than horizontally. This is a natural variation and some tissue types are covered with more than one. Furthermore, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons from those limbs that are dorsal.
