What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the spine. Dermatomes can help doctors to construct models of the cord that help in diagnosing. Two major maps are accepted by medical specialists. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are widely used. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas which are connected to a particular nerve bundle. In cases of spinal injury, pain may be felt in a dermatome which is innervated by that nerve. Similarly, the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you experience a 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 supplied by a single spinal nerve. The nerves transmit motor, sensory and autonomic signals. They form a part of the peripheral nerve system, which connects the brain and all the body. A dermatome may suffer from a spinal lesion. If one of these dermatomes gets injured, it is able to be treated easily with an local anesthetic.
Dermatomes in the thoracic region are labeled with letters-numbers that illustrate the connection between the region along with the sensor nerve that serves the area. For instance C1 spinal nerve doesn’t have a dematome, however those spinal nerves that are identified as C1-C8 T9, which corresponds to the belly button. Dermatomes are layered horizontally on the trunk, those on the extremities tend to be long.
Dermatome Map
The dermatome map is an integral part of textbooks that teach anatomy. But, the map is not uniform both inside and inter-textbook. Its naming is inconsistent and certain textbooks have different maps on different pages. This can be particularly challenging when the authors of different chapters disagree on the choice of dermatome maps. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett but do not include appropriate references. Moreover, four textbooks use maps with no citations, and one of them is one that only cites secondary sources.
Dermatomes are the areas of skin that receives sensory stimulation from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip more inferiorly than horizontally. This is a natural variation and certain tissues have more than one. In addition to this, dorsal spinal rootlets may have intrathecal intersegmental anastomoses with sensory neurons in Dorsal limbs.
