What is a Dermatome?
The term “dermatome” refers to a tissue that covers your spinal cord. Dermatomes play a crucial role in allowing physicians to build images of spinal cord that can be useful in diagnosing. Two major maps are recognized by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are frequently employed. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.
Dermatomes are skin regions that are linked to a specific nerve. In cases of spinal injury, the pain could be felt in a dermatome, which is surrounded by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you suffer from 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. The nerves transmit sensory, motor, and autonomic messages. They form part of the peripheral nervous system, which connects brain and other parts of the body. A dermatome may suffer from a spinal lesion. If one of these gets injured, it is able to be easily treated with an local anesthetic.
The dermatomes of the thoracic region are identified with letter-number combinations that show how the region is connected along with the sensor nerve that serves this area. For example, the C1 spinal nerve does not have a dermatome. However, others spinal nerves have been identified as C1-C8 and T9 refers to belly button. Dermatomes are layered in horizontally on the trunk however, dermatomes in the extremities are usually longitudinal.
Dermatome Map
The dermatome map is an integral part of textbooks teaching anatomy. But, the map is inconsistent both intra and inter-textbook. The name is not consistent as are some textbooks that have distinct maps on different pages. This is especially problematic when the authors of several chapters differ in their choice of dermatome maps. Many textbooks use the maps of Foerster, Keegan, and Garrett however they don’t provide appropriate references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that uses 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 situated, but they tend to dip lower than horizontally. This is a natural variation, and some tissue types are covered with more than one. Also dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons of those limbs that are dorsal.
