Dermatome Map Of Head By Annie Campbell University Of Du Flickr – If you have ever wondered what the human dermatome’s map looks, you’ve come to the right spot. Before we go to an image, it’s important to look at what a dermatome actually is. What are the different kinds? Most importantly, why is it necessary to understand dermatomes in order to comprehend 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 is a part of the spine. Dermatomes play a crucial role in allowing doctors to develop diagrams of the spine that are useful for diagnosis. Two major maps are accepted by medical experts. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are frequently utilized. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that are attached to a particular nerve bundle. When there is a spinal cord injury, the pain could be felt in a dermatome which is surrounded by the nerve. Similarly, the pain caused by shingles outbreaks can be felt in specific spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by one spinal nerve. These nerves provide motor, sensory and autonomic messages. They form part of the peripheral nerve system which connects the brain and rest of the body. A dermatome may become affected due to a spinal injury. If one of these dermatomes becomes injured, it can be easily treated using the use of a local anesthetic.
Dermatomes in the thoracic region are labeled with letters-numbers that illustrate how the region is connected as well as the nerve that supplies that region. For example C1 spinal nerve doesn’t have a dermatome. However, all spinal nerves in the region are labeled as C1-C8 and T9 is a reference with the belly button. Dermatomes are layered in horizontally on the trunk and dermatomes located that are located on the extremities are generally longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks that teach anatomy. But, the map is inconsistent both intra and inter-textbook. The name is not consistent, and some textbooks feature distinct maps on different pages. This can be particularly challenging when the authors of multiple chapters are not unified in their choice of dermatome maps. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett but don’t include adequate references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip more inferiorly than horizontally. This is a natural variation, and some tissues are covered by more than one dermatome. Additionally, dorsal spinal rootlets may have intrathecal intersegmental anastomoses with sensory neurons of those limbs that are dorsal.
