What are the different types? And, most importantly, why is it important to learn about 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 the spine. Dermatomes can help physicians to build images of spinal cord, which aid in the diagnosis. Two major maps are accepted by medical specialists. They are the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still frequently employed. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin areas that are attached to a particular nerve bundle. In the case of spinal cord injury, pain can be felt in a dermatome, which is connected to that nerve. Similarly, the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you feel neurologic condition or pain that involves the dermatome, you should consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is provided by the spinal nerve. These nerves relay motor, sensory, and autonomic information. They form an element of the peripheral nervous system, which connects the brain and other parts of the body. A dermatome may get affected because of a spinal cord injury. If one of these gets injured, it is able to be easily treated using an local anesthetic.
Dermatomes in the thoracic area are marked using letter-number sequences that demonstrate the connection between the region as well as the nerve that is responsible for the area. For example the C1 spinal nerve doesn’t have a dematome, however others spinal nerves have been identified as C1-C8, while T9 corresponds with the belly button. Dermatomes are laid horizontally along the trunk, those that are located on the extremities are generally longitudinal.
Dermatome Map
The dermatome map is the most common element in textbooks that cover anatomy. However, the dermatome maps is not consistent both within and inter-textbook. The names are inconsistent, and some textbooks feature distinct maps on different pages. This is especially problematic when the authors of multiple chapters differ in their choice of dermatome maps. The majority of textbooks utilize the maps of Foerster, Keegan, and Garrett however they don’t provide appropriate references. Moreover, four textbooks use maps that do not have citations, such as one that cites only secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation from the dorsal root of one spinal nerve. Dermatomes aren’t evenly located, but they tend to be more inferior than horizontally. This is a natural variation and some tissues may be covered by multiple dermatomes. In addition to this, dorsal spinal rootlets may have intrathecal intersegmental anastomoses with sensory neurons in those limbs that are dorsal.
