What is a Dermatome?

The term “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help physicians to build images of spinal cord that can be useful in diagnosing. Two maps are widely accepted by medical specialists. There is the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are commonly employed. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.

Dermatomes are skin areas that are linked to a particular nerve bundle. When there is a spinal cord injury, the pain could be felt in a dermatome, which is innervated by that nerve. Similar to the pain that is caused by shingles outbreaks is felt by specific spinal nerves. If you feel pain or neurological condition involving the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin supplied by a single spinal nerve. These nerves provide sensory, motor as well as autonomic information. They form an element of the peripheral nerve system which connects the brain with the rest of the body. Dermatomes can get affected because of a spinal injury. If one of these dermatomes becomes injured, it can be easily treated with an local anesthetic.

Dermatomes in the thoracic region have been labeled with letter-number combinations that show how the region is connected as well as the nerve which supplies that area. For instance the C1 spinal nerve doesn’t have a dermatome. However, all spinal nerves in the region are labeled as C1-C8, while T9 corresponds to the belly button. Dermatomes are layered in horizontally on the trunk, and dermatomes located in the extremities are usually long.

The dermatome map is an integral part of textbooks that cover anatomy. The dermatome map is inconsistency both within and inter-textbook. The names are inconsistent and some textbooks include different maps on various pages. This is particularly problematic when the authors of multiple chapters differ in their choice of dermatome maps. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide adequate references. Additionally, four textbooks employ maps with no citations. This includes one that cites only secondary sources.

Dermatomes are the areas of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t evenly located, but they tend to dip lower than horizontally. This is a natural variation and certain tissues are covered by more than one dermatome. Also dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons from the dorsal limbs.
