7 Dermatomes YouTube – If you have ever wondered how the human dermatome map appears, then you’re at the right place. Before we get to an image, it’s important to look at what a dermatome actually is. What are the various types? And most importantly, why is it important to know about dermatomes in order to understand how the body works. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes are important in allowing doctors to construct diagrams of the spine that are useful for diagnosis. Two major maps are regarded as valid by medical professionals. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and remain often used. The trigeminal nerve , as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin areas that are linked to a particular nerve. When there is a spinal cord injuries, pain may be felt in a dermatome, which is innervated by that nerve. In the same way, the pain triggered by shingles outbreaks can be felt in specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome region, you need to consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by the spinal nerve. These nerves relay sensory, motor, and autonomic signals. They form an element of the peripheral nervous system, which connects the brain and all the body. A dermatome may suffer from a spinal lesion. If one of these dermatomes becomes injured, it could be treated easily with an local anesthetic.
The dermatomes of the thoracic area are marked with letter-number combinations that show the connection between the region as well as the nerve which supplies that area. For example C1’s spinal nerve does not have a dematome, however all spinal nerves in the region are identified as C1-C8 T9, which corresponds to belly button. Dermatomes are layered horizontally on the trunk, while dermatomes on the extremities tend to be longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks that cover anatomy. However, the dermatome map is not consistent both within and inter-textbook. The names are inconsistent and some textbooks include different maps on various pages. This can be particularly challenging 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 but don’t include adequate references. Moreover, four textbooks use maps without citations, including one that only cites secondary sources.
Dermatomes are the areas of skin that receives sensory innervation from the dorsal branch of one spinal nerve. Dermatomes aren’t uniformly located, but they tend to dip more inferiorly than horizontally. This is a natural variation, and certain tissues are covered by more than one dermatome. In addition to this dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons that originate from the dorsal parts of the limbs.
