Before we get to this map, lets talk about the definition of a dermatome. What are the different kinds? And, most importantly, why is it essential to know about dermatomes in order to comprehend how the body works. Read on to find out 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 help doctors to construct images of spinal cord that aid in the diagnosis. Two major maps are regarded as valid by medical professionals. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are widely used. The trigeminal and maxillary nerve are the biggest dermatomes.
Dermatomes are skin-like areas that connect to a specific nerve bundle. In cases of spinal injuries, pain may be felt in a dermatome which is innervated by that nerve. In the same way, the pain triggered by an outbreak of shingles is felt by specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by the spinal nerve. These nerves carry motor, sensory, as well as autonomic information. They form an element of the peripheral nervous system, which connects brain and all the body. A dermatome may suffer from a spinal cord lesion. When one of these dermatomes gets injured, it is able to be easily treated using a local anesthetic.
Dermatomes in the thoracic region have been labeled with letters-numbers that illustrate how the region is connected in question and the sensory nerve that supplies this area. For example, the C1 spinal nerve doesn’t have a dermatome, but others spinal nerves have been labeled as C1-C8 T9, which corresponds to the belly button. Dermatomes are laid horizontally along the trunk, those on the extremities tend to be in a longitudinal.
Dermatome Map
Dermatome maps are an integral part of textbooks teaching anatomy. However, the dermatome maps is not consistent both within and inter-textbook. Its name isn’t consistent as are some textbooks that 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 map. Most textbooks use map of 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 only cites secondary sources.
The dermatome is the area of skin that receives sensory input 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 some tissue types are covered with more than one. Additionally dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons in those limbs that are dorsal.
