Before we look at the map, let’s take a look at what a dermatome is. What are the various types? And most importantly, why is it essential to know about dermatomes in order to comprehend your body. Read on to find out more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help doctors to create images of spinal cord, which can be useful in diagnosing. Two maps are widely accepted by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are commonly used. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin areas that are linked to a particular nerve bundle. In cases of spinal injuries, pain may be felt in a dermatome, which 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 experience a discomfort or neurological issue involving the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is provided by the spinal nerve. The nerves transmit 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 get affected because of a spinal lesion. If one of these gets injured, it is able to be easily treated with an local anesthetic.
The dermatomes of the thoracic region are labeled with letters-numbers that illustrate the connection between the region as well as the nerve that serves that region. For instance, the C1 spinal nerve doesn’t have a dematome, however all spinal nerves in the region are labeled C1 – C8 T9, which corresponds to belly button. Dermatomes are layered vertically on the trunk those on the extremities tend to be in a longitudinal.
Dermatome Map
The dermatome map is one of the common features of textbooks that cover anatomy. However, the dermatome map is inconsistency both within and inter-textbook. Its name isn’t consistent and some textbooks include different maps on different pages. This is especially problematic when the authors of different chapters are not unified in their choice of dermatome maps. A majority of textbooks employ the Maps of Foerster, Keegan, and Garrett however, they do not provide proper references. Additionally, four textbooks employ maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the areas of skin that receives sensory input from the dorsal root of one spinal nerve. Dermatomes aren’t evenly located, but they tend to be more inferior than horizontally. This is a natural variation, and certain tissue types are covered with more than one. Additionally dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons from the dorsal parts of the limbs.
