What is a Dermatome?
The term “dermatome” refers to a tissue that covers your spinal cord. Dermatomes are important in allowing doctors to construct models of the cord that can be useful in diagnosing. Two maps are widely accepted by medical professionals. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are often utilized. The trigeminal and maxillary nerve are the biggest dermatomes.
Dermatomes are skin areas that are attached to a particular nerve bundle. In cases of spinal injury, pain may be experienced in a dermatome that is surrounded by the nerve. The same is true for the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by only one spinal nerve. These nerves provide motor, sensory and autonomic messages. They form part of the peripheral nerve system which connects the brain with the all the body. Dermatomes can suffer from a spinal lesion. When one of these dermatomes is injured, it can be treated easily with local anesthetic.
The dermatomes of the thoracic region are labeled by letter-number combinations, which show the connection between the area as well as the nerve which supplies that area. For example C1 spinal nerve does not have a dermatome, but others spinal nerves have been labeled C1 – C8 T9, which corresponds with the belly button. Dermatomes are layered horizontally on the trunk, while dermatomes that are located on the extremities are generally in a longitudinal.
Dermatome Map
The dermatome map is one of the common features of textbooks that cover anatomy. However, the dermatome map is not consistent both within and inter-textbook. The name is not consistent as are some textbooks that have different maps on various pages. This can be particularly challenging when the authors of different chapters differ in their choice of dermatome maps. Many textbooks use the Maps of Foerster, Keegan, and Garrett however, they do not provide appropriate references. Additionally, four textbooks employ maps with no citations, and one of them is one that refers to only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip lower than horizontally. This is a natural variation and certain tissues are covered by more than one dermatome. Furthermore dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons that originate from the dorsal parts of the limbs.
