Before we go to our map, we’ll discuss what a dermatome actually is. What are the various kinds? And most importantly, why is it essential to be aware of dermatomes order to understand how the body works. Continue reading to learn more. You may 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 cord of the spinal. Dermatomes help doctors to develop diagrams of the spine, which are useful for diagnosis. Two major maps are regarded as valid by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain widely used. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.
Dermatomes are areas of skin which are connected to a specific nerve. In the case of spinal cord injuries, pain may be experienced in a dermatome that is controlled by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you are experiencing pain or neurological condition involving the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is provided by a single spinal nerve. These nerves relay sensory, motor and autonomic information. They form an element of the peripheral nervous system that connects the brain to the all the body. A dermatome may suffer from a spinal lesion. If one of these gets injured, it is able to be easily treated using the use of a local anesthetic.
Dermatomes in the thoracic region are identified with letters-numbers that illustrate the connection between the area along with the sensor nerve that is responsible for that region. For example, the C1 spinal nerve does not have a dematome, however the other spinal nerves are labeled C1-C8, while T9 corresponds to the belly button. Dermatomes are laid vertically on the trunk while dermatomes on the extremities tend to be longitudinal.
Dermatome Map
The dermatome map is the most common element in textbooks that teach anatomy. But, the map is inconsistency both within and inter-textbook. The name is not consistent and certain textbooks have different maps on different pages. This is particularly problematic when the authors of different chapters disagree on the choice of dermatome maps. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide the proper references. Furthermore, four textbooks make use of maps with no citations. This includes one that refers to only secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal branch 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 are covered by more than one dermatome. Furthermore dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons of the dorsal limbs.
