Before we go to this map, lets take a look at what a dermatome actually is. What are the different kinds? And, most importantly, why is it important to understand dermatomes in order to know more about the human body. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers your spinal cord. Dermatomes help doctors to develop diagrams of the spine that help in diagnosing. Two major maps are accepted by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain widely employed. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin regions that are linked to a particular nerve. In cases of spinal injuries, pain may be felt in a dermatome which is connected to that nerve. In the same way, the pain triggered by shingles outbreaks can be felt in specific spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome region, you need to consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by a single spinal nerve. These nerves carry sensory, motor as well as autonomic information. They form part of the peripheral nervous system, which connects brain and rest of the body. A dermatome may become affected due to a spinal lesion. If one of these dermatomes is injured, it can be treated easily with the use of a local anesthetic.
The dermatomes of the thoracic region are labeled using letter-number sequences that demonstrate the connection between the region and the sensory nerve that serves that area. For example C1’s spinal nerve does not possess a dermatome, however all spinal nerves in the region are labeled C1 – C8 T9, which corresponds to belly button. Dermatomes are laid vertically on the trunk and dermatomes located on the extremities tend to be longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks that teach anatomy. But, the map is inconsistency both within and inter-textbook. Its naming is inconsistent, and some textbooks feature various maps on different pages. This is particularly problematic in the event that the authors of various chapters disagree on the choice of dermatome map. A majority of textbooks employ the map of Foerster, Keegan, and Garrett however they don’t provide adequate references. Additionally, four textbooks employ maps with no citations, and one of them is one that only cites secondary sources.
Dermatomes are the parts of skin that receives sensory innervation from the dorsal root of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip more inferiorly than horizontally. This is a natural variation and certain tissues may be covered by multiple dermatomes. Additionally dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons of those limbs that are dorsal.
