What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes can help doctors to develop maps of the spinal cord, which aid in the diagnosis. Two major maps are recognized by medical professionals. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are widely utilized. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that are linked to a specific nerve bundle. In the case of spinal cord injury, 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 can be felt in particular spinal nerves. If you feel neurologic condition or pain that involves the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by a single spinal nerve. These nerves relay sensory, motor and autonomic signals. They form a part of the peripheral nervous system, which connects brain and all the body. Dermatomes can get affected because of a spinal lesion. If one of these dermatomes becomes injured, it can be easily treated using a local anesthetic.
The dermatomes of the thoracic region have been labeled by letter-number combinations, which show the connection between the area along with the sensor nerve that supplies this area. For example C1’s spinal nerve doesn’t have a dermatome. However, all spinal nerves in the region are labeled as C1-C8 and T9 is a reference to belly button. Dermatomes are laid horizontally on the trunk and dermatomes located that are located on the extremities are generally in a longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks that teach anatomy. The dermatome map is inconsistent both intra and inter-textbook. The name is not consistent, and some textbooks feature distinct maps on different pages. This can be particularly challenging when the authors of different chapters disagree on the choice of dermatome map. Most textbooks use diagrams drawn by Foerster, Keegan, and Garrett but don’t include proper references. Additionally, four textbooks employ maps without citations, including one that only cites secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly found, but they tend to dip lower than horizontally. This is a natural variation, and certain tissues are covered by more than one dermatome. Additionally dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons of Dorsal limbs.
