What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the spine. Dermatomes play a crucial role in allowing physicians to build diagrams of the spine that help in diagnosing. Two major maps are regarded as valid by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are often utilized. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.

Dermatomes are areas of skin that are linked to a particular nerve bundle. In cases of spinal injury, pain can be felt in a dermatome that is surrounded by the nerve. The same is true for the pain caused by shingles outbreaks is felt by specific spinal nerves. If you feel pain or neurological condition involving the dermatome, you should visit a doctor.

Dermatomes are the segments of skin that is supplied by the spinal nerve. These nerves carry sensory, motor, and autonomic signals. They form part of the peripheral nerve system, which connects the brain with the all the body. Dermatomes can become affected due to a spinal injury. If one of these becomes injured, it can be treated easily with an local anesthetic.

Dermatomes in the thoracic region are identified by letter-number combinations, which show how the region is connected and the sensory nerve that serves this area. For example C1 spinal nerve doesn’t have a dematome, however those spinal nerves that are labeled C1 – C8 and T9 is a reference with the belly button. Dermatomes are laid horizontally on the trunk those on the extremities tend to be long.

Dermatome Map

The dermatome map is the most common element in textbooks that cover anatomy. But, the map is inconsistent both intra and inter-textbook. Its naming is inconsistent as are some textbooks that have different maps on different pages. This is especially problematic when the authors of different chapters differ in their choice of dermatome map. The majority of textbooks utilize the maps of Foerster, Keegan, and Garrett however they don’t provide proper references. Moreover, four textbooks use maps that do not have citations, such as one that uses only secondary sources.

The dermatome is the area of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip less inferiorly than horizontally. This is an inherent variation and some tissues have more than one. Also dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons in the dorsal parts of the limbs.
