What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the spine. Dermatomes are important in allowing doctors to create maps of the spinal cord, which help in diagnosing. Two major maps are recognized by medical experts. These are: the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are frequently utilized. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are areas of skin which are connected to a specific nerve. In cases of spinal injuries, pain may be felt in a dermatome which is surrounded by the nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in specific spinal nerves. If you suffer from discomfort or neurological issue involving the dermatome, it is recommended that you consult a physician.

Dermatomes are segments of skin that is supplied by a single spinal nerve. The nerves transmit sensory, motor, and autonomic signals. They form an element of the peripheral nerve system, which connects the brain and all the body. A dermatome may suffer from a spinal lesion. If one of these gets injured, it is able to be easily treated with the use of a local anesthetic.
Dermatomes in the thoracic region have been labeled with letter-number combinations that show the connection between the area as well as the nerve that is responsible for this area. For example C1 spinal nerve doesn’t possess a dermatome, however all spinal nerves in the region are identified as C1-C8 T9, which corresponds to the belly button. Dermatomes are layered in horizontally along the trunk, however, dermatomes in the extremities are usually in a longitudinal.
Dermatome Map
The dermatome map is an integral part of textbooks teaching anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. The name is not consistent and certain textbooks have various maps on different pages. This can be particularly challenging when the authors of different chapters are not unified in their choice of dermatome map. Many textbooks use the maps of Foerster, Keegan, and Garrett however, they do not provide adequate references. In addition, four textbooks utilize maps with no citations, and one of them is one that uses only secondary sources.
The dermatome is the area of skin that receives sensory input from the dorsal root of one spinal nerve. Dermatomes aren’t evenly situated, but they tend to dip more inferiorly than horizontally. This is a natural variation and certain tissues have more than one. In addition to this, dorsal spinal rootlets may have intrathecal intersegmental anastomoses with sensory neurons in the dorsal limbs.
