Dermatomes Definition Chart And Diagram – If you have ever wondered how the human dermatome map appears, then you’re at the right spot. Before we look at this map, lets look at what is a dermatome. What are the different types? Most importantly, what is the reason to be aware of dermatomes order to know more about how the body works. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes can help physicians to build diagrams of the spine, which can be useful in diagnosing. Two major maps are accepted by medical experts. There is the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are commonly employed. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.
Dermatomes are areas of skin which are connected to a specific nerve. In cases of spinal cord injury, pain can be experienced in a dermatome that is surrounded by the nerve. In the same way, the pain triggered by shingles outbreaks is felt by specific spinal nerves. If you are experiencing pain or neurological condition involving the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by one spinal nerve. The nerves transmit motor, sensory and autonomic information. They form a part of the peripheral nerve system that connects the brain to the other parts of the body. A dermatome may suffer from a spinal cord injury. When one of these dermatomes is injured, it can be easily treated using a 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 area. For example C1’s spinal nerve does not possess a dermatome, however all spinal nerves in the region are labeled C1 – C8 T9, which corresponds with the belly button. Dermatomes are layered horizontally along the trunk, while dermatomes in the extremities are usually in a longitudinal.
Dermatome Map
Dermatome maps are an integral part of textbooks that cover anatomy. However, the dermatome map is not consistent both within and inter-textbook. The names are inconsistent, and some textbooks feature different maps on various pages. This is especially problematic when the authors of multiple chapters disagree on the choice of dermatome map. Most textbooks use maps of Foerster, Keegan, and Garrett however, they do not provide appropriate references. In addition, four textbooks utilize maps with no citations, and one of them is one that refers to only secondary sources.
Dermatomes are the areas of skin that receives sensory input from the dorsal roots of one spinal nerve. The dermatomes are not uniformly found, but they tend to dip less inferiorly than horizontally. This is a natural variation and certain tissue types are covered with more than one. Additionally, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons of Dorsal limbs.
