Metacarpal Fractures Core EM – If you’ve ever thought about how the human dermatome chart is, you’ve come to the right spot. Before we get to this map, lets talk about the definition of a dermatome. What are the various types? And most importantly, why is it important to learn about dermatomes in order to better understand our body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes can help doctors to create diagrams of the spine, which help in diagnosing. Two major maps are recognized by medical experts. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s, and are often employed. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin regions which are connected to a specific nerve bundle. In cases of spinal injuries, pain may be felt in a dermatome which is controlled by the nerve. The same is true for the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you suffer from pain or neurological condition involving the dermatome, you should consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by one spinal nerve. These nerves provide sensory, motor, as well as autonomic information. They form an element of the peripheral nervous system, which connects brain and other parts of the body. Dermatomes can suffer from a spinal lesion. When one of these dermatomes gets injured, it is able to be treated easily with the use of a local anesthetic.
Dermatomes in the thoracic region are labeled with letters-numbers that illustrate the connection between the region as well as the nerve which supplies the area. For instance, the C1 spinal nerve does not have a dematome, however the other spinal nerves are labeled C1 – C8 T9, which corresponds to the belly button. Dermatomes are layered in horizontally on the trunk, and dermatomes located on the extremities are typically in a longitudinal.
Dermatome Map
The dermatome map is a common feature of textbooks teaching anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. Its name isn’t consistent and certain textbooks have various maps on different pages. This is especially problematic in the event that the authors of various chapters differ in their choice of dermatome maps. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett but do not include appropriate references. Additionally, four textbooks employ maps that do not have citations, such as one that only cites secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip less inferiorly than horizontally. This is a normal variation and certain tissue types are covered with more than one. Additionally dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons of Dorsal limbs.
