What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes help doctors to create images of spinal cord, which help in diagnosing. Two major maps are regarded as valid by medical professionals. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are commonly utilized. The trigeminal nerve and the maxillary nerve are the largest dermatomes.
Dermatomes are skin areas which are connected to a specific nerve. In the case of spinal cord injury, the pain could be felt in a dermatome, which is surrounded by the nerve. The same is true for the pain caused by an outbreak of shingles is felt by specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is provided by a single spinal nerve. These nerves relay motor, sensory and autonomic signals. They form a part of the peripheral nervous system, which connects the brain with the rest of the body. Dermatomes can become affected due to a spinal cord lesion. When one of these dermatomes gets injured, it is able to be treated easily with local anesthetic.
The dermatomes of the thoracic region are labeled with letters-numbers that illustrate how the region is connected along with the sensor nerve that is responsible for that area. For instance C1 spinal nerve does not have a dermatome, but all spinal nerves in the region are labeled C1-C8 and T9 is a reference to belly button. Dermatomes are layered in horizontally on the trunk, those in the extremities are usually longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks that cover anatomy. However, the dermatome maps is not uniform both inside and inter-textbook. Its name isn’t consistent and certain textbooks have distinct maps on different pages. This can be particularly challenging when the authors of multiple chapters are not unified in their choice of dermatome map. Most textbooks use diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide the proper references. Moreover, four textbooks use maps that do not have citations, such as one that cites only secondary sources.
Dermatomes are the areas of skin that receives sensory stimulation from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to be more inferior than horizontally. This is a natural variation, and some tissue types are covered with more than one. Additionally dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons that originate from those limbs that are dorsal.
