Before we move on to this map, lets discuss what a dermatome actually is. What are the different types? And, most importantly, why is it necessary to understand dermatomes in order to know more about our body. 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 is a part of the spinal cord. Dermatomes are important in allowing doctors to construct models of the cord that aid in the diagnosis. Two major maps are recognized by medical professionals. There is the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are widely employed. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin regions which are connected to a particular nerve. In cases of spinal injury, the pain could be experienced in a dermatome that is surrounded by the nerve. The same is true for the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you feel pain or neurological condition involving the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by a single spinal nerve. These nerves carry sensory, motor and autonomic signals. They form part of the peripheral nervous system which connects the brain and other parts of the body. Dermatomes can become affected due to a spinal lesion. If one of these becomes injured, it could be easily treated using a local anesthetic.
Dermatomes in the thoracic region are identified with letters-numbers that illustrate how the region is connected along with the sensor nerve that serves the area. For example C1’s spinal nerve does not possess a dermatome, however others spinal nerves have been labeled as C1-C8 and T9 is a reference to belly button. Dermatomes are layered vertically on the trunk and dermatomes located that are located on the extremities are generally linear.
Dermatome Map
The dermatome map is one of the common features of textbooks teaching anatomy. However, the dermatome map is not uniform both inside and inter-textbook. Its name isn’t consistent and certain textbooks have different maps on various pages. This is particularly problematic when the authors of multiple chapters disagree on the choice of dermatome maps. Many textbooks use the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide the proper references. Moreover, four textbooks use maps that do not have citations, such as one that uses only secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation from the dorsal root of one spinal nerve. The dermatomes are not uniformly found, 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 have intrathecal intersegmental anastomoses to sensory neurons of the dorsal parts of the limbs.
