Before we move on to our map, we’ll look at the definition of a dermatome. What are the different types? And most importantly, why is it important to understand dermatomes in order to understand how the body works. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the spinal cord. Dermatomes play a crucial role in allowing doctors to develop images of spinal cord, which are useful for diagnosis. Two major maps are regarded as valid by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are commonly employed. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that are attached to a specific nerve. In cases of spinal cord injury, pain may be felt in a dermatome which is controlled by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you are experiencing nerve pain or neurological problem affecting the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by the spinal nerve. These nerves relay motor, sensory as well as autonomic information. They form a part of the peripheral nerve system which connects the brain with the rest of the body. A dermatome may be affected by a spinal lesion. If one of these gets injured, it is able to be easily treated using local anesthetic.
Dermatomes in the thoracic area are marked with letters-numbers that illustrate the connection between the area and the sensory nerve that serves that area. For example C1 spinal nerve does not have a dermatome. However, others spinal nerves have been identified as C1-C8 and T9 is a reference to belly button. Dermatomes are layered horizontally on the trunk, those that are located on the extremities are generally long.
Dermatome Map
Dermatome maps are the most common element in textbooks that cover anatomy. But, the map 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 in the event that the authors of various chapters differ in their choice of dermatome maps. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett but don’t include adequate references. In addition, four textbooks utilize maps with no citations. This includes one that refers to only secondary sources.
The dermatome is the area of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip less inferiorly than horizontally. This is a normal variation and certain tissue types are covered with more than one. Furthermore dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons in those limbs that are dorsal.
