Spinal Nerve Radiculopathy Nerve – If you’ve ever thought about how the human dermatome chart appears, then you’re at the right spot. Before we get to an image, it’s important to discuss what is a dermatome. What are the different kinds? Most importantly, why is it necessary to understand dermatomes in order to better understand our body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers your spinal cord. Dermatomes help doctors to develop models of the cord, which help in diagnosing. Two maps are widely accepted by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were created in the 1930s, and are frequently utilized. The trigeminal and maxillary nerve are the largest dermatomes.
Dermatomes are skin areas that are attached to a specific nerve. In cases of spinal cord injury, the pain could be experienced in a dermatome that is surrounded by the nerve. The same is true for the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you feel nerve pain or neurological problem affecting the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by a single spinal nerve. The nerves transmit motor, sensory as well as autonomic information. They form an element of the peripheral nervous system which connects brain and rest of the body. Dermatomes can become affected due to a spinal cord injury. When one of these dermatomes becomes injured, it can be easily treated with the use of a local anesthetic.
The dermatomes of the thoracic region are identified with letters-numbers that illustrate the connection between the region as well as the nerve that serves this area. For example C1’s spinal nerve does not have a dermatome, but all spinal nerves in the region are labeled C1-C8 T9, which corresponds with the belly button. Dermatomes are layered horizontally along the trunk, and dermatomes located on the extremities tend to be long.
Dermatome Map
Dermatome maps are an integral part of textbooks that cover anatomy. But, the map is inconsistent both intra and inter-textbook. Its naming is inconsistent, and some textbooks feature different maps on various pages. This is particularly problematic when the authors of different chapters do not agree on the selection of dermatome map. Most textbooks use Maps of Foerster, Keegan, and Garrett however they don’t provide adequate references. In addition, four textbooks utilize maps with no citations. This includes one that refers to only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly placed, however they tend to dip less inferiorly than horizontally. This is a natural variation, and certain tissues may be covered by multiple dermatomes. Also dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons from those limbs that are dorsal.
