Dermatome Map Of Head By Annie Campbell University Of Du Flickr – If you’ve ever wondered what the human dermatome map looks, you’ve come to the right spot. Before we go to an image, it’s important to discuss what is a dermatome. What are the various types? And most importantly, what is the reason to know about dermatomes in order to know more about our body. 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 covers the spinal cord. Dermatomes help physicians to build models of the cord, which aid in the diagnosis. Two major maps are accepted by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s, and are frequently employed. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin regions which are connected to a particular nerve bundle. When there is a spinal cord injury, the pain could be felt in a dermatome, which is connected to that nerve. In the same way, the pain triggered by shingles outbreaks is felt by specific spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome, you should consult with a physician.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is supplied by only one spinal nerve. These nerves provide motor, sensory and autonomic signals. They form an element of the peripheral nervous system that connects the brain to the all the body. A dermatome may be affected by a spinal injury. If one of these becomes injured, it can be treated easily with local anesthetic.
The dermatomes of the thoracic region are identified using letter-number sequences that demonstrate the relationship between the area in question and the sensory nerve which supplies that area. For instance C1’s spinal nerve doesn’t have a dermatome. However, all spinal nerves in the region are labeled C1-C8, while T9 corresponds to the belly button. Dermatomes are layered horizontally on the trunk, while dermatomes on the extremities are typically long.
Dermatome Map
Dermatome maps are the most common element in textbooks teaching anatomy. However, the dermatome map is not consistent both within and inter-textbook. The names are inconsistent and certain textbooks have distinct maps on different pages. This is particularly problematic when the authors of different chapters disagree on the choice of dermatome map. Most textbooks use diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide the proper references. Furthermore, four textbooks make use of maps without citations, including one that only cites secondary sources.
Dermatomes are the regions of skin that receives sensory input from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly found, but they tend to dip lower than horizontally. This is an inherent variation and certain tissues may be covered by multiple dermatomes. Also dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons of the dorsal limbs.
