What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes help doctors to create diagrams of the spine that help in diagnosing. Two maps are widely accepted by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain often utilized. The trigeminal and maxillary nerve are the largest dermatomes.
Dermatomes are areas of skin that are attached to a particular nerve. When there is a spinal cord injury, pain can be felt in a dermatome that is innervated by that nerve. Similarly, the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you feel discomfort or neurological issue involving the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is provided by a single spinal nerve. The nerves transmit sensory, motor as well as autonomic information. They form an element of the peripheral nerve system that connects the brain to the all the body. A dermatome may get affected because of a spinal cord lesion. If one of these dermatomes is injured, it can be treated easily with local anesthetic.
The dermatomes of the thoracic region are identified by letter-number combinations, which show how the region is connected and the sensory nerve that serves the area. For instance the C1 spinal nerve doesn’t have a dermatome, but others spinal nerves have been identified as C1-C8 and T9 is a reference to belly button. Dermatomes are laid vertically on the trunk those on the extremities are typically in a longitudinal.
Dermatome Map
The dermatome map is a common feature of textbooks that cover anatomy. The dermatome map is not uniform both inside and inter-textbook. Its name isn’t consistent and certain textbooks have distinct maps on different pages. This is especially problematic in the event that the authors of various chapters do not agree on the selection of dermatome map. Many textbooks use the map of Foerster, Keegan, and Garrett but do not include the proper references. Additionally, four textbooks employ maps with no citations, and one of them is one that uses 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 always evenly placed, however they tend to dip lower than horizontally. This is a normal variation and some tissues are covered by more than one dermatome. Furthermore dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons of those limbs that are dorsal.
