Dermatomes And Myotomes Anatomy Geeky Medics – If you have ever wondered how the human dermatome map looks, you’ve come to the right place. Before we get to the map, let’s talk about the definition of a dermatome. What are the different types? Most importantly, why is it important to be aware of dermatomes order to comprehend 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 cord of the spinal. Dermatomes help physicians to build images of spinal cord that are useful for diagnosis. Two major maps are regarded as valid by medical professionals. The Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are widely used. The trigeminal nerve , as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin areas that are attached to a particular nerve bundle. In cases of spinal injuries, pain may be felt in a dermatome, which is innervated by that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in particular spinal nerves. If you experience a nerve pain or neurological problem affecting the dermatome, it is recommended that you see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by one spinal nerve. These nerves carry sensory, motor, as well as autonomic information. They form an element of the peripheral nerve system that connects the brain to the rest of the body. Dermatomes can become affected due to a spinal injury. If one of these dermatomes becomes injured, it could be easily treated with an local anesthetic.
The dermatomes of the thoracic region have been labeled by letter-number combinations, which show the connection between the area as well as the nerve that serves that region. For instance, the C1 spinal nerve does not have a dermatome, but the other spinal nerves are labeled C1-C8, while T9 corresponds to belly button. Dermatomes are layered in horizontally along the trunk, and dermatomes located on the extremities tend to be long.
Dermatome Map
The dermatome map is the most common element in textbooks that cover anatomy. But, the map is inconsistency both within and inter-textbook. Its name isn’t consistent as are some textbooks that have distinct maps on different pages. This is particularly problematic in the event that the authors of various chapters differ in their choice of dermatome maps. Many textbooks use the maps of Foerster, Keegan, and Garrett however, they do not provide adequate references. Moreover, four textbooks use maps without citations, including one that cites only secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip lower than horizontally. This is a normal variation and certain tissue types are covered with more than one. Also dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons that originate from the dorsal parts of the limbs.
