What is a Dermatome?

The term “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes play a crucial role in allowing doctors to create models of the cord that can be useful in diagnosing. Two maps are widely accepted by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are frequently used. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.

Dermatomes are skin areas that are linked to a particular nerve. In the case of spinal cord injury, the pain could be felt in a dermatome, which is innervated by that nerve. The same is true for the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin supplied by a single spinal nerve. These nerves provide sensory, motor, and autonomic messages. They form a part of the peripheral nervous system which connects the brain with the all the body. Dermatomes can suffer from a spinal injury. When one of these dermatomes becomes injured, it could be treated easily with a local anesthetic.

Dermatomes in the thoracic region are labeled with letters-numbers that illustrate the connection between the area as well as the nerve that serves the area. For instance, the C1 spinal nerve does not have a dematome, however others spinal nerves have been labeled C1 – C8 and T9 refers with the belly button. Dermatomes are layered in horizontally on the trunk, while dermatomes on the extremities tend to be long.

Dermatome Map

The dermatome map is the most common element in textbooks that cover anatomy. The dermatome map is inconsistent both intra and inter-textbook. Its name isn’t consistent and some textbooks include different maps on various pages. This can be particularly challenging when the authors of multiple chapters disagree on the choice of dermatome maps. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide the proper references. In addition, four textbooks utilize maps without citations, including one that cites only secondary sources.

Dermatomes are the parts of skin that receives sensory input from the dorsal roots of one spinal nerve. The dermatomes are not uniformly found, but they tend to dip less inferiorly than horizontally. This is a natural variation and some tissues may be covered by multiple dermatomes. Also dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons that originate from Dorsal limbs.
