Before we get to our map, we’ll discuss what a dermatome is. What are the different 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 might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes can help doctors to construct diagrams of the spine, which can be useful in diagnosing. Two maps are widely accepted by medical professionals. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are widely used. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.
Dermatomes are skin regions which are connected to a particular nerve. In cases of spinal cord injury, pain can be experienced in a dermatome that is connected to that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in particular spinal nerves. If you feel neurologic condition or pain that involves the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is provided by only one spinal nerve. The nerves transmit sensory, motor, and autonomic information. They form part of the peripheral nerve system that connects the brain to the rest of the body. A dermatome may become affected due to a spinal lesion. When one of these dermatomes is injured, it can be treated easily with local anesthetic.
The dermatomes of the thoracic region are identified with letters-numbers that illustrate the connection between the region as well as the nerve that supplies that area. For instance C1 spinal nerve doesn’t have a dematome, however others spinal nerves have been labeled as C1-C8 and T9 refers to belly button. Dermatomes are laid horizontally along the trunk, and dermatomes located in the extremities are usually long.
Dermatome Map
The dermatome map is an integral part of textbooks teaching anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. Its name isn’t consistent and certain textbooks have different maps on different pages. This is particularly problematic in the event that the authors of various chapters disagree on the choice of dermatome maps. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide proper references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that cites only secondary sources.
The dermatome is the area of skin that receives sensory stimulation from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip lower than horizontally. This is a normal variation and certain tissues may be covered by multiple dermatomes. Furthermore dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons that originate from the dorsal parts of the limbs.
