What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes can help physicians to build images of spinal cord, which are useful for diagnosis. Two major maps are accepted by medical specialists. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s, and are often used. The trigeminal nerve , as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin areas that connect to a specific nerve bundle. In the case of spinal cord injuries, pain may 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 are experiencing pain or neurological condition involving the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by one spinal nerve. These nerves provide sensory, motor, and autonomic information. They form a part of the peripheral nerve system, which connects brain and all the body. A dermatome may get affected because of a spinal cord injury. When one of these dermatomes is injured, it can be easily treated with the use of a local anesthetic.
The dermatomes of the thoracic region are identified with letter-number combinations that show how the region is connected in question and the sensory nerve that serves this area. For instance the C1 spinal nerve does not possess 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 layered in horizontally on the trunk, while dermatomes in the extremities are usually long.
Dermatome Map
The dermatome map is an integral part of textbooks that cover anatomy. The dermatome map is not consistent both within and inter-textbook. The name is not consistent and some textbooks include various maps on different pages. This can be particularly challenging when the authors of multiple chapters are not unified in their choice of dermatome map. The majority of textbooks utilize the map of Foerster, Keegan, and Garrett however they don’t provide proper references. Moreover, four textbooks use maps with no citations. This includes one that uses only secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal root of a spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip lower than horizontally. This is an inherent variation and certain tissues have more than one. Additionally dorsal spinal rootlets could have intrathecal intersegmental anastomoses with sensory neurons of Dorsal limbs.
