Dermatomes Development Maps TeachMeAnatomy – If you have ever wondered what the human dermatome’s map appears, then you’re at the right place. Before we get to the map, let’s discuss what is a dermatome. What are the various kinds? And, most importantly, why is it essential to understand dermatomes in order to better understand how the body works. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.
What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes are important in allowing physicians to build images of spinal cord that are useful for diagnosis. Two major maps are accepted by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still commonly used. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas that are linked to a specific nerve. When there is a spinal cord injury, pain may be felt in a dermatome, which is connected to that nerve. Similar to the pain that is caused by shingles outbreaks can be felt in particular spinal nerves. If you experience a pain or neurological condition involving the dermatome, it is recommended that you visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by only one spinal nerve. These nerves provide motor, sensory as well as autonomic information. They form part of the peripheral nerve system, which connects the brain with the rest of the body. Dermatomes can get affected because of a spinal cord lesion. If one of these dermatomes gets injured, it is able to be treated easily with an local anesthetic.
The dermatomes of the thoracic area are marked with letters-numbers that illustrate the connection between the region and the sensory nerve which supplies that area. For example the C1 spinal nerve doesn’t have a dermatome. However, all spinal nerves in the region are labeled as C1-C8, while T9 corresponds with the belly button. Dermatomes are layered in horizontally on the trunk, however, dermatomes that are located on the extremities are generally linear.
Dermatome Map
Dermatome maps are one of the common features of textbooks that cover anatomy. However, the dermatome map is not consistent both within and inter-textbook. The names are inconsistent, and some textbooks feature distinct maps on different pages. This is particularly problematic when the authors of several chapters are not unified in their choice of dermatome maps. The majority of textbooks utilize the maps of Foerster, Keegan, and Garrett but don’t include appropriate references. Additionally, four textbooks employ maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the areas of skin that receives sensory innervation from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip less inferiorly than horizontally. This is a natural variation and some tissues have more than one. In addition to this dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons in the dorsal parts of the limbs.
