Dermatomes And Myotomes Anatomy Geeky Medics – If you have ever wondered what the human dermatome’s map appears, then you’re at the right spot. Before we move on to an image, it’s important to take a look at what a dermatome is. What are the various types? The most important thing is what is the reason to be aware of dermatomes order to better understand how the body works. Read on to find out more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help doctors to construct maps of the spinal cord, which are useful for diagnosis. Two major maps are regarded as valid by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are often employed. The trigeminal and 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, pain can 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 suffer from neurologic condition or pain that involves the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is provided by only one spinal nerve. These nerves provide motor, sensory and autonomic signals. They form part of the peripheral nerve system, which connects the brain and rest of the body. Dermatomes can get affected because of a spinal cord injury. If one of these dermatomes becomes injured, it could be easily treated using a local anesthetic.
The dermatomes of the thoracic region are labeled using letter-number sequences that demonstrate the relationship between the area along with the sensor nerve which supplies that area. For example the C1 spinal nerve doesn’t possess a dermatome, however the other spinal nerves are labeled as C1-C8 and T9 refers to belly button. Dermatomes are layered in horizontally along the trunk, however, dermatomes that are located on the extremities are generally longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks that cover anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. Its name isn’t consistent, and some textbooks feature different maps on different pages. This is especially problematic when the authors of several chapters disagree on the choice of dermatome maps. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett but do not include adequate references. In addition, four textbooks utilize maps that do not have citations, such as one that uses only secondary sources.
Dermatomes are the areas of skin that receives sensory stimulation from the dorsal root of one spinal nerve. The dermatomes are not uniformly placed, however they tend to dip more inferiorly than horizontally. This is a natural variation, and certain tissues have more than one. Also dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons that originate from Dorsal limbs.
