Dermatomes And Myotomes Sensation Anatomy Geeky Medics – If you’ve ever wanted to know how the human dermatome chart looks, you’ve come to the right spot. Before we go to the map, let’s take a look at what a dermatome is. What are the different kinds? Most importantly, why is it necessary to know about dermatomes in order to understand the human body. 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 is a part of the spine. Dermatomes help doctors to create models of the cord that help in diagnosing. Two major maps are regarded as valid by medical specialists. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still widely utilized. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas that connect to a particular nerve bundle. In the case of spinal cord injury, the pain could be experienced in a dermatome that is surrounded by the nerve. The same is true for the pain caused by shingles outbreaks is felt by specific spinal nerves. If you are experiencing nerve pain or neurological problem affecting the dermatome region, you need to consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by only one spinal nerve. These nerves relay motor, sensory as well as autonomic information. They form an element of the peripheral nervous system which connects brain and all the body. Dermatomes can get affected because of a spinal lesion. If one of these dermatomes gets injured, it is able to be easily treated using local anesthetic.
Dermatomes in the thoracic region have been labeled using letter-number sequences that demonstrate the connection between the region as well as the nerve that serves the area. For instance C1’s spinal nerve doesn’t have a dematome, however the other spinal nerves are labeled C1 – C8 and T9 is a reference to the belly button. Dermatomes are layered in horizontally on the trunk while dermatomes in the extremities are usually long.
Dermatome Map
The dermatome map is a common feature of textbooks that teach anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. The name is not consistent and certain textbooks have various maps on different pages. This is especially problematic when the authors of several chapters disagree on the choice of dermatome map. Many textbooks use the Maps of Foerster, Keegan, and Garrett however they don’t provide the proper references. Moreover, four textbooks use maps that do not have citations, such as one that only cites secondary sources.
Dermatomes are the areas of the skin that receives sensory information from the dorsal branch of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to be more inferior than horizontally. This is a natural variation and some tissues may be covered by multiple dermatomes. Also dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons that originate from those limbs that are dorsal.
