What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes play a crucial role in allowing physicians to build maps of the spinal cord that help in diagnosing. Two maps are widely accepted by medical experts. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still frequently utilized. The trigeminal and maxillary nerves are the two largest dermatomes.
Dermatomes are skin regions that are attached to a particular nerve bundle. When there is a spinal cord injury, pain can be experienced in a dermatome that is innervated by that nerve. Similarly, the pain caused by shingles outbreaks can be felt in specific spinal nerves. If you are experiencing nerve pain or neurological problem affecting the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by the spinal nerve. The nerves transmit sensory, motor as well as autonomic information. They form part of the peripheral nervous system that connects the brain to the all the body. A dermatome may be affected by a spinal cord lesion. When one of these dermatomes is injured, it can be easily treated with a local anesthetic.
The dermatomes of the thoracic region are identified using letter-number sequences that demonstrate how the region is connected as well as the nerve that is responsible for that region. For instance C1’s spinal nerve does not have a dermatome. However, all spinal nerves in the region are labeled as C1-C8 and T9 is a reference to belly button. Dermatomes are layered vertically on the trunk while dermatomes on the extremities tend to be in a longitudinal.
Dermatome Map
The dermatome map is the most common element in textbooks that teach anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. The names are inconsistent, and some textbooks feature various maps on different pages. This can be particularly challenging when the authors of different chapters are not unified in their choice of dermatome maps. Most textbooks use maps of Foerster, Keegan, and Garrett but do not include proper references. Furthermore, four textbooks make use of maps with no citations. This includes one that refers to only secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly situated, but they tend to dip more inferiorly than horizontally. This is a natural variation, and some tissues have more than one. Additionally dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons in the dorsal limbs.
