Before we get to this map, lets discuss what is a dermatome. What are the various types? And, most importantly, why is it essential to be aware of dermatomes order to know more about how the body works. Read on to find out 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 play a crucial role in allowing doctors to construct images of spinal cord, which can be useful in diagnosing. Two maps are widely accepted by medical professionals. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are frequently utilized. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin regions that are linked to a specific nerve bundle. In cases of spinal injury, pain can be felt in a dermatome that is controlled by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt on specific spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome, it is recommended that you see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by one spinal nerve. These nerves provide sensory, motor, and autonomic messages. They form a part of the peripheral nervous system, that connects the brain to the other parts of the body. Dermatomes can suffer from a spinal cord lesion. If one of these dermatomes gets injured, it is able to be easily treated using the use of a local anesthetic.
The dermatomes of the thoracic region have been labeled by letter-number combinations, which show the connection between the area in question and the sensory nerve that is responsible for that area. For instance, the C1 spinal nerve doesn’t 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 laid horizontally on the trunk, those in the extremities are usually in a longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks that cover anatomy. However, the dermatome 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 multiple chapters do not agree on the selection of dermatome map. The majority of textbooks utilize 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 branch of one spinal nerve. The dermatomes are not uniformly situated, but they tend to be more inferior than horizontally. This is an inherent variation and certain tissues have more than one. Also dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons of Dorsal limbs.
