Before we get to this map, lets discuss what is a dermatome. What are the various types? The most important thing is why is it necessary to know about dermatomes in order to comprehend our body. 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 help doctors to construct models of the cord that can be useful in diagnosing. Two major maps are regarded as valid by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still often used. The trigeminal nerve as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are skin-like areas that connect to a specific nerve bundle. When there is a spinal cord injury, pain can be felt in a dermatome, which is innervated by that nerve. In the same way, the pain triggered by an outbreak of shingles is felt by specific spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin supplied by a single spinal nerve. The nerves transmit sensory, motor, and autonomic signals. They form a part of the peripheral nervous system that connects the brain to the other parts of the body. Dermatomes can become affected due to a spinal injury. If one of these becomes injured, it could be easily treated using an local anesthetic.
The dermatomes of the thoracic region have been labeled by letter-number combinations, which show the relationship between the area along with the sensor nerve that supplies this area. For example, the C1 spinal nerve does not have a dermatome. However, the other spinal nerves are identified as C1-C8 and T9 refers to belly button. Dermatomes are layered horizontally on the trunk, and dermatomes located that are located on the extremities are generally linear.
Dermatome Map
Dermatome maps are the most common element in textbooks that cover anatomy. But, the map is inconsistent both intra and inter-textbook. Its naming is inconsistent, and some textbooks feature different maps on different pages. This is especially problematic when the authors of multiple chapters do not agree on the selection of dermatome maps. Many textbooks use the map of Foerster, Keegan, and Garrett however they don’t provide adequate references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the parts of skin that receives sensory innervation from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip lower than horizontally. This is a natural variation and some tissue types are covered with more than one. In addition to this dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons of the dorsal limbs.
