Before we move on to the map, let’s talk about the definition of a dermatome. What are the various types? And most importantly, why is it essential to be aware of dermatomes order to better understand the human body. Read on to find out more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers your spinal cord. Dermatomes help physicians to build images of spinal cord, which aid in the diagnosis. Two major maps are recognized by medical specialists. 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 nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin regions that are linked to a particular nerve. When there is a spinal cord injuries, pain may be felt in a dermatome which is connected to that nerve. The same is true for the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you suffer from nerve pain or neurological problem affecting the dermatome region, you need to consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin supplied by one spinal nerve. These nerves provide motor, sensory as well as autonomic information. They form a part of the peripheral nerve system which connects the brain and rest of the body. A dermatome may become affected due to a spinal injury. If one of these dermatomes gets injured, it is able to be easily treated using the use of a local anesthetic.
The dermatomes of the thoracic region are identified with letters-numbers that illustrate the relationship between the area in question and the sensory nerve that supplies this area. For instance C1 spinal nerve does not have a dermatome, but others spinal nerves have been identified as C1-C8 T9, which corresponds to the belly button. Dermatomes are layered horizontally on the trunk however, dermatomes on the extremities are typically linear.
Dermatome Map
Dermatome maps are a common feature of textbooks that teach anatomy. The dermatome map is not consistent both within and inter-textbook. Its name isn’t consistent as are some textbooks that have various maps on different pages. This is especially problematic in the event that the authors of various chapters disagree on the choice of dermatome maps. Most textbooks use diagrams drawn by Foerster, Keegan, and Garrett but do not include proper references. Furthermore, four textbooks make use of maps that do not have citations, such as one that only cites secondary sources.
Dermatomes are the regions of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip less inferiorly than horizontally. This is a normal variation and certain tissue types are covered with more than one. Additionally dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons that originate from the dorsal limbs.
