What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes are important in allowing doctors to construct diagrams of the spine that help in diagnosing. Two major maps are recognized by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are commonly used. The trigeminal nerve , as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin-like areas that are attached to a specific nerve bundle. When there is a spinal cord injury, pain may be felt in a dermatome that is connected to that nerve. In the same way, the pain triggered by an outbreak of shingles can be felt on specific spinal nerves. If you feel pain or neurological condition involving the dermatome, it is recommended that you see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by a single spinal nerve. The nerves transmit motor, sensory and autonomic signals. They form a part of the peripheral nerve system which connects brain and all the body. A dermatome may suffer from a spinal cord lesion. If one of these gets injured, it is able to be easily treated using the use of a local anesthetic.
The dermatomes of the thoracic area are marked with letters-numbers that illustrate how the region is connected along with the sensor nerve which supplies that area. For example C1’s spinal nerve does not have a dematome, however others spinal nerves have been identified as C1-C8 and T9 refers with the belly button. Dermatomes are layered horizontally on the trunk, while dermatomes in the extremities are usually long.
Dermatome Map
The dermatome map is a common feature of textbooks that cover anatomy. However, the dermatome maps is not consistent both within and inter-textbook. Its naming is inconsistent, and some textbooks feature different maps on different pages. This is particularly problematic in the event that the authors of various chapters are not unified in their choice of dermatome map. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett but don’t include the proper references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that only cites secondary sources.
The dermatome is the area of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t evenly located, but they tend to dip lower than horizontally. This is a normal variation and certain tissues may be covered by multiple dermatomes. In addition to this dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons in the dorsal limbs.
