Dermatomes Diagram Spinal Nerves And Locations – If you have ever wondered how the human dermatome map appears, then you’re at the right spot. Before we move on to the map, let’s take a look at what a dermatome is. What are the different kinds? Most importantly, why is it necessary to be aware of dermatomes order to understand how the body works. Continue reading to learn more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that covers your spinal cord. Dermatomes can help doctors to develop images of spinal cord, which help in diagnosing. Two major maps are recognized by medical professionals. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and remain often used. The trigeminal and maxillary nerve are the largest dermatomes.
Dermatomes are skin areas that are attached to a particular nerve. In the case of spinal cord injury, the pain could be felt in a dermatome which is surrounded by the nerve. In the same way, the pain triggered by shingles outbreaks is felt by specific spinal nerves. If you experience a nerve pain or neurological problem affecting the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by the spinal nerve. These nerves carry motor, sensory, and autonomic information. They form a part of the peripheral nerve system which connects the brain with the other parts of the body. Dermatomes can be affected by a spinal cord injury. When one of these dermatomes becomes injured, it can be treated easily with the use of a local anesthetic.
The dermatomes of the thoracic region are labeled by letter-number combinations, which show the connection between the area in question and the sensory nerve which supplies that area. For instance C1’s spinal nerve does not have a dematome, however all spinal nerves in the region are labeled as C1-C8 T9, which corresponds to the belly button. Dermatomes are laid horizontally on the trunk however, dermatomes in the extremities are usually longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks that teach anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. Its name isn’t consistent as are some textbooks that have different maps on different pages. This is especially problematic when the authors of several chapters do not agree on the selection of dermatome maps. Most textbooks use map of Foerster, Keegan, and Garrett however, they do not provide appropriate references. Moreover, four textbooks use maps that do not have citations, such as one that cites only secondary sources.
The dermatome is the area of skin that receives sensory input from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly located, but they tend to dip less inferiorly than horizontally. This is an inherent variation and certain tissues may be covered by multiple dermatomes. Additionally, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons of the dorsal parts of the limbs.
