What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers your spinal cord. Dermatomes play a crucial role in allowing doctors to construct images of spinal cord that can be useful in diagnosing. Two major maps are recognized by medical professionals. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are still widely used. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.
Dermatomes are skin-like areas that are linked to a specific nerve bundle. In cases of spinal injury, pain can be experienced in a dermatome that is innervated by that nerve. In the same way, the pain triggered by shingles outbreaks can be felt in specific spinal nerves. If you feel discomfort or neurological issue involving the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by only one spinal nerve. The nerves transmit motor, sensory and autonomic messages. They form a part of the peripheral nervous system which connects the brain and rest of the body. A dermatome may suffer from a spinal cord injury. If one of these becomes injured, it could be treated easily with the use of a local anesthetic.
Dermatomes in the thoracic region have been labeled with letters-numbers that illustrate the connection between the region as well as the nerve which supplies that region. For instance C1 spinal nerve does not have a dermatome, but those spinal nerves that are labeled C1-C8 and T9 is a reference to the belly button. Dermatomes are laid horizontally along the trunk, those on the extremities are typically long.
Dermatome Map
The dermatome map is the most common element in textbooks teaching anatomy. But, the map is inconsistency both within and inter-textbook. The names are inconsistent and certain textbooks have different maps on different pages. This is especially problematic in the event that the authors of various chapters differ in their choice of dermatome maps. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett but don’t include adequate references. Moreover, four textbooks use maps with no citations. This includes one that cites only secondary sources.
The dermatome is the area of the skin that receives sensory information from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly placed, however they tend to dip more inferiorly than horizontally. This is a normal variation and certain tissues are covered by more than one dermatome. Also dorsal spinal rootlets could have intrathecal intersegmental anastomoses with sensory neurons that originate from those limbs that are dorsal.
