What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers your spinal cord. Dermatomes play a crucial role in allowing doctors to construct images of spinal cord, which are useful for diagnosis. Two major maps are regarded as valid by medical professionals. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still frequently used. The trigeminal nerve , as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are skin areas that are attached to a particular nerve bundle. In the case of spinal cord injury, the pain could be felt in a dermatome that is surrounded by the nerve. In the same way, the pain triggered by shingles outbreaks can be felt on specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin supplied by only one spinal nerve. These nerves relay sensory, motor, and autonomic information. They form a part of the peripheral nerve system which connects the brain with the rest of the body. Dermatomes can suffer from a spinal lesion. If one of these gets injured, it is able to be easily treated with local anesthetic.
The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate the connection between the area and the sensory nerve that supplies that area. For instance C1’s spinal nerve doesn’t possess a dermatome, however the other spinal nerves are labeled C1 – C8 and T9 is a reference to belly button. Dermatomes are layered horizontally along the trunk, those on the extremities are typically longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks teaching anatomy. The dermatome map is inconsistent both intra and inter-textbook. Its name isn’t consistent as are some textbooks that have different maps on different pages. This is particularly problematic when the authors of different chapters differ in their choice of dermatome maps. Most textbooks use Maps of Foerster, Keegan, and Garrett but do not include the proper references. Moreover, four textbooks use maps with no citations. This includes one that refers to only secondary sources.
Dermatomes are the areas of skin that receives sensory input from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly found, but they tend to dip less inferiorly than horizontally. This is a normal variation and certain tissues have more than one. Furthermore dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons in those limbs that are dorsal.
