Before we look at our map, we’ll take a look at what is a dermatome. What are the various kinds? And, most importantly, why is it essential to understand dermatomes in order to know more about your 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 the spinal cord. Dermatomes help physicians to build models of the cord that can be useful in diagnosing. Two maps are widely accepted by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are commonly used. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.
Dermatomes are skin regions that are linked to a particular nerve. In cases of spinal cord injuries, pain may be felt in a dermatome which is innervated by that nerve. Similar to the pain that is caused by shingles outbreaks is felt by specific spinal nerves. If you suffer from nerve pain or neurological problem affecting the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin supplied by one spinal nerve. These nerves relay motor, sensory and autonomic information. They form an element of the peripheral nerve system which connects brain and other parts of the body. A dermatome may suffer from a spinal lesion. When one of these dermatomes gets injured, it is able to be easily treated with a local anesthetic.
The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate the relationship between the area along with the sensor nerve which supplies that area. For instance the C1 spinal nerve doesn’t possess a dermatome, however those spinal nerves that are labeled as C1-C8 and T9 refers to the belly button. Dermatomes are layered in horizontally along the trunk, those in the extremities are usually long.
Dermatome Map
The dermatome map is the most common element in textbooks teaching anatomy. However, the dermatome map is not uniform both inside and inter-textbook. The name is not consistent and some textbooks include different maps on different pages. This can be particularly challenging when the authors of different chapters differ in their choice of dermatome maps. Many textbooks use the map of Foerster, Keegan, and Garrett however, they do not provide appropriate references. Additionally, four textbooks employ maps without citations, including one that refers to only secondary sources.
Dermatomes are the regions of the skin that receives sensory information from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip more inferiorly than horizontally. This is a natural variation, and certain tissues have more than one. In addition to this dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons of those limbs that are dorsal.
