Dermatomes And Myotomes Anatomy Geeky Medics – If you have ever wondered how the human dermatome map appears, then you’re at the right place. Before we go to an image, it’s important to talk about what a dermatome actually is. What are the different kinds? The most important thing is why is it important to learn about dermatomes in order to understand the human body. 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 the spinal cord. Dermatomes help doctors to develop maps of the spinal cord, which help in diagnosing. Two major maps are recognized by medical experts. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s, and are often used. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin regions that connect to a specific nerve bundle. When there is a spinal cord injury, pain may be felt in a dermatome which is connected to that nerve. The same is true for the pain caused by shingles outbreaks can be felt in specific spinal nerves. If you feel neurologic condition or pain that involves the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by the spinal nerve. These nerves relay motor, sensory and autonomic signals. They form an element of the peripheral nervous system which connects the brain with the other parts of the body. A dermatome may be affected by a spinal injury. When one of these dermatomes becomes injured, it can be treated easily with local anesthetic.
Dermatomes in the thoracic area are marked by letter-number combinations, which show the connection between the region as well as the nerve that supplies that area. For example the C1 spinal nerve doesn’t have a dermatome. However, others spinal nerves have been identified as C1-C8, while T9 corresponds to the belly button. Dermatomes are laid horizontally on the trunk however, dermatomes on the extremities tend to be in a longitudinal.
Dermatome Map
Dermatome maps are an integral part of textbooks that cover anatomy. But, the map is inconsistency 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 multiple chapters disagree on the choice of dermatome map. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett but do not include the proper references. Moreover, four textbooks use maps without citations, including one that cites only secondary sources.
Dermatomes are the areas of skin that receives sensory input from the dorsal branch of one spinal nerve. The dermatomes are not uniformly located, but they tend to be more inferior than horizontally. This is a natural variation, and some tissues are covered by more than one dermatome. Additionally dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons of Dorsal limbs.
