2 Dermatomes Infamedic – If you’ve ever wanted to know what the human dermatome’s map looks, you’ve come to the right spot. Before we get to an image, it’s important to talk about what a dermatome is. What are the various kinds? Most importantly, why is it necessary to be aware of dermatomes order to know more about how the body works. Continue reading to learn more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes are important in allowing physicians to build models of the cord, which help in diagnosing. Two major maps are recognized by medical professionals. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain frequently used. The trigeminal nerve and the maxillary nerve are the largest dermatomes.
Dermatomes are skin-like areas that are attached to a particular nerve bundle. In cases of spinal cord injury, the pain could be experienced in a dermatome that is controlled by the nerve. In the same way, the pain triggered by shingles outbreaks can be felt in particular spinal nerves. If you experience a nerve pain or neurological problem affecting the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by only one spinal nerve. These nerves carry motor, sensory as well as autonomic information. They form part of the peripheral nerve system, which connects the brain with the all the body. Dermatomes can become affected due to a spinal injury. When one of these dermatomes becomes injured, it can be treated easily with local anesthetic.
The dermatomes of the thoracic region have been labeled with letter-number combinations that show the connection between the area along with the sensor nerve that supplies this 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 the belly button. Dermatomes are layered horizontally on the trunk however, dermatomes that are located on the extremities are generally long.
Dermatome Map
The dermatome map is one of the common features of textbooks that cover anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. The names are inconsistent and some textbooks include different maps on various pages. This is particularly problematic when the authors of multiple chapters are not unified in their choice of dermatome maps. Many textbooks use the diagrams drawn by Foerster, Keegan, and Garrett but don’t include appropriate references. Furthermore, four textbooks make use of maps with no citations. This includes one that cites only secondary sources.
Dermatomes are the areas of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly placed, however they tend to be more inferior than horizontally. This is a normal variation and some tissues are covered by more than one dermatome. Furthermore dorsal spinal rootlets could have intrathecal intersegmental anastomoses to sensory neurons of Dorsal limbs.
