And, most importantly, why is it necessary to be aware of dermatomes order to better understand your 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 the cord of the spinal. Dermatomes are important in allowing doctors to develop maps of the spinal cord that can be useful in diagnosing. 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 frequently used. The trigeminal and maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas that are linked to a specific nerve. In the case of spinal cord injuries, pain may be felt in a dermatome that is controlled by the nerve. The same is true for the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you are experiencing nerve pain or neurological problem affecting the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by one spinal nerve. The nerves transmit sensory, motor, as well as autonomic information. They form an element of the peripheral nerve system, which connects brain and other parts of the body. Dermatomes can be affected by a spinal cord injury. When one of these dermatomes gets injured, it is able to be treated easily with local anesthetic.
Dermatomes in the thoracic region are identified with letter-number combinations that show the connection between the region as well as the nerve that is responsible for the area. For example, the C1 spinal nerve doesn’t possess a dermatome, however the other spinal nerves are labeled as C1-C8 T9, which corresponds to belly button. Dermatomes are layered in horizontally on the trunk, and dermatomes located on the extremities tend to be in a longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks teaching anatomy. However, the dermatome map is not consistent both within and inter-textbook. Its naming is inconsistent, and some textbooks feature different maps on different pages. This can be particularly challenging when the authors of multiple chapters disagree on the choice of dermatome maps. Many textbooks use the maps of Foerster, Keegan, and Garrett however they don’t provide the proper references. In addition, four textbooks utilize maps that do not have citations, such as one that refers to only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal root of one spinal nerve. Dermatomes aren’t evenly located, but they tend to be more inferior than horizontally. This is an inherent variation and certain tissues have more than one. In addition to this dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons of Dorsal limbs.
