What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes play a crucial role in allowing doctors to create images of spinal cord that help in diagnosing. Two major maps are regarded as valid by medical specialists. The Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still commonly utilized. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that are linked to a particular nerve bundle. In cases of spinal injuries, pain may be felt in a dermatome, which is connected to that nerve. Similar to the pain that is caused by shingles outbreaks can be felt in specific spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome, it is recommended that you see a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is provided by the spinal nerve. The nerves transmit motor, sensory, as well as autonomic information. They form part of the peripheral nervous system that connects the brain to the rest of the body. Dermatomes can get affected because of a spinal lesion. If one of these dermatomes becomes injured, it can be treated easily with an local anesthetic.
Dermatomes in the thoracic region are labeled using letter-number sequences that demonstrate how the region is connected and the sensory nerve that supplies this area. For example the C1 spinal nerve doesn’t possess a dermatome, however all spinal nerves in the region are labeled C1-C8, while T9 corresponds with the belly button. Dermatomes are layered in horizontally along the trunk, those in the extremities are usually linear.
Dermatome Map
The dermatome map is one of the common features of textbooks that cover anatomy. But, the map is inconsistency both within and inter-textbook. The names are inconsistent and certain textbooks have distinct maps on different pages. This can be particularly challenging when the authors of multiple chapters do not agree on the selection of dermatome map. Many textbooks use the maps of Foerster, Keegan, and Garrett however, they do not provide adequate references. Moreover, four textbooks use maps that do not have citations, such as one that cites only secondary sources.
Dermatomes are the areas of skin that receives sensory stimulation from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly situated, but they tend to dip lower than horizontally. This is a natural variation, and some tissues may be covered by multiple dermatomes. Additionally dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons in the dorsal limbs.
