Before we go to this map, lets talk about the definition of a dermatome. What are the different types? Most importantly, why is it important to learn about dermatomes in order to better understand how the body works. Read on to find out more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes play a crucial role in allowing doctors to create maps of the spinal cord, which aid in the diagnosis. Two major maps are accepted by medical professionals. They are the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still often utilized. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that are attached to a particular nerve bundle. In cases of spinal injury, pain may be experienced in a dermatome that is surrounded by the nerve. Similarly, the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you suffer from pain or neurological condition involving the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by the spinal nerve. These nerves relay sensory, motor and autonomic information. They form a part of the peripheral nerve system that connects the brain to the rest of the body. Dermatomes can get affected because of a spinal cord injury. If one of these is injured, it can be easily treated using a local anesthetic.
The dermatomes of the thoracic area are marked by letter-number combinations, which show the connection between the region and the sensory nerve that supplies that area. For example the C1 spinal nerve doesn’t have a dermatome. However, the other spinal nerves are labeled as C1-C8 and T9 is a reference with the belly button. Dermatomes are layered in horizontally on the trunk and dermatomes located in the extremities are usually long.
Dermatome Map
Dermatome maps are a common feature of textbooks teaching anatomy. However, the dermatome maps is not consistent both within and inter-textbook. The names are inconsistent and some textbooks include various maps on different pages. This is particularly problematic when the authors of multiple chapters do not agree on the selection of dermatome map. Many textbooks use the Maps of Foerster, Keegan, and Garrett but don’t include appropriate references. Moreover, four textbooks use maps with no citations. This includes one that only cites secondary sources.
The dermatome is the area of skin that receives sensory innervation from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly located, but they tend to dip lower than horizontally. This is a natural variation, and certain tissues have more than one. Also dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons of Dorsal limbs.
