What are the different kinds? And, most importantly, why is it necessary to know about dermatomes in order to understand our body. Continue reading to learn more. You might be amazed!

What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes help doctors to create diagrams of the spine that can be useful in diagnosing. Two major maps are accepted by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are often utilized. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.
Dermatomes are skin areas which are connected to a specific nerve. In cases of spinal cord injury, pain can be felt in a dermatome, which is surrounded by the nerve. The same is true for the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you feel neurologic condition or pain that involves the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is provided by the spinal nerve. These nerves carry sensory, motor, and autonomic information. They form an element of the peripheral nerve system which connects brain and other parts of the body. A dermatome may be affected by a spinal injury. If one of these is injured, it can be treated easily with local anesthetic.
The dermatomes of the thoracic region have been labeled using letter-number sequences that demonstrate how the region is connected and the sensory nerve that is responsible for the area. For instance C1 spinal nerve does not have a dermatome. However, all spinal nerves in the region are labeled as C1-C8 and T9 is a reference to the belly button. Dermatomes are laid vertically on the trunk however, dermatomes that are located on the extremities are generally long.
Dermatome Map
The dermatome map is a common feature of textbooks that cover anatomy. However, the dermatome maps is not consistent both within and inter-textbook. Its name isn’t consistent and certain textbooks have various maps on different pages. This is particularly problematic when the authors of different chapters disagree on the choice of dermatome maps. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett but don’t include proper references. Additionally, four textbooks employ maps that do not have citations, such as one that cites only secondary sources.
Dermatomes are the parts of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly situated, but they tend to dip less inferiorly than horizontally. This is a natural variation, and certain tissues are covered by more than one dermatome. Additionally dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons that originate from the dorsal parts of the limbs.
