Dermatomes And Myotomes Sensation Anatomy Geeky Medics – If you’ve ever wondered how the human dermatome map looks, you’ve come to the right spot. Before we get to the map, let’s take a look at the definition of a dermatome. What are the different kinds? And most importantly, why is it necessary to know about dermatomes in order to comprehend our body. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.
What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes are important in allowing physicians to build images of spinal cord, which aid in the diagnosis. Two major maps are accepted by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still widely utilized. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.
Dermatomes are skin areas that connect to a specific nerve. In cases of spinal injury, pain can be experienced in a dermatome that is controlled by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt in specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome region, you need to consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by a single spinal nerve. These nerves carry sensory, motor as well as autonomic information. They form an element of the peripheral nervous system, that connects the brain to the other parts of the body. Dermatomes can suffer from a spinal cord injury. If one of these is injured, it can be treated easily with local anesthetic.
The dermatomes of the thoracic region have been labeled using letter-number sequences that demonstrate the connection between the region as well as the nerve which supplies that area. For example the C1 spinal nerve does not have a dematome, however the other spinal nerves are identified as C1-C8, while T9 corresponds with the belly button. Dermatomes are laid horizontally along the trunk, those in the extremities are usually linear.
Dermatome Map
Dermatome maps are the most common element in textbooks that cover anatomy. But, the map is not consistent both within and inter-textbook. Its naming is inconsistent as are some textbooks that have different maps on different pages. This can be particularly challenging when the authors of multiple chapters differ in their choice of dermatome maps. Many textbooks use the Maps of Foerster, Keegan, and Garrett but don’t include adequate references. In addition, four textbooks utilize maps with no citations, and one of them is one that only cites secondary sources.
Dermatomes are the areas of skin that receives sensory innervation from the dorsal root of a spinal nerve. Dermatomes aren’t evenly situated, but they tend to dip lower than horizontally. This is a normal variation and some tissue types are covered with more than one. Additionally, dorsal spinal rootlets may contain intrathecal intersegmental connections with sensory neurons that originate from Dorsal limbs.
