What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes help doctors to create diagrams of the spine, which aid in the diagnosis. Two major maps are regarded as valid by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are frequently utilized. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.

Dermatomes are skin areas which are connected to a specific nerve. In cases of spinal cord injury, pain can be felt in a dermatome which is controlled by the nerve. In the same way, the pain triggered by shingles outbreaks can be felt on specific spinal nerves. If you suffer from nerve pain or neurological problem affecting the dermatome region, you need to consult a physician.

What are Some Examples of Dermatomes?

Dermatomes are segments of skin that is supplied by one spinal nerve. The nerves transmit sensory, motor as well as autonomic information. They form a part of the peripheral nerve system, which connects brain and all the body. A dermatome may suffer from a spinal cord injury. If one of these dermatomes gets injured, it is able to be easily treated with an local anesthetic.

Dermatomes in the thoracic region are identified by letter-number combinations, which show the connection between the area in question and the sensory nerve that supplies the area. For example C1’s spinal nerve does not have a dermatome, but others spinal nerves have been labeled C1-C8 and T9 refers to the belly button. Dermatomes are layered horizontally on the trunk, while dermatomes on the extremities tend to be long.

Dermatome Map

Dermatome maps are an integral part of textbooks that cover anatomy. The dermatome map is not uniform both inside and inter-textbook. The names are inconsistent and some textbooks include distinct maps on different pages. This is especially problematic when the authors of different chapters disagree on the choice of dermatome maps. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide the proper references. In addition, four textbooks utilize maps that do not have citations, such as one that only cites secondary sources.

Dermatomes are the parts of skin that receives sensory input from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly situated, but they tend to dip less inferiorly than horizontally. This is a natural variation, and some tissue types are covered with more than one. Furthermore dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons that originate from the dorsal parts of the limbs.
