Dermatomes And Myotomes Anatomy Geeky Medics – If you’ve ever wanted to know what the human dermatome map looks, you’ve come to the right place. Before we get to an image, it’s important to talk about what a dermatome is. What are the various kinds? And most importantly, why is it necessary to be aware of dermatomes order to comprehend how the body works. Read on to find out more. You might 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 construct diagrams of the spine, which are useful for diagnosis. Two maps are widely accepted by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are commonly used. The trigeminal and maxillary nerves are the two largest dermatomes.
Dermatomes are skin-like areas that are attached to a specific nerve. In cases of spinal injuries, pain may be felt in a dermatome which is controlled by the nerve. In the same way, the pain triggered by shingles outbreaks can be felt in specific spinal nerves. If you are experiencing discomfort or neurological issue involving 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 only one spinal nerve. These nerves provide motor, sensory, as well as autonomic information. They form part of the peripheral nerve system, that connects the brain to the rest of the body. Dermatomes can be affected by a spinal lesion. If one of these dermatomes is injured, it can be easily treated with the use of a local anesthetic.
Dermatomes in the thoracic region are labeled with letter-number combinations that show the connection between the area in question and the sensory nerve that serves the area. For instance C1 spinal nerve doesn’t have a dermatome, but those spinal nerves that are labeled C1-C8, while T9 corresponds to belly button. Dermatomes are laid horizontally along the trunk, those in the extremities are usually long.
Dermatome Map
Dermatome maps are an integral part of textbooks that cover anatomy. However, the dermatome map is not consistent both within and inter-textbook. The names are inconsistent as are some textbooks that have various maps on different pages. This is particularly problematic when the authors of several chapters differ in their choice of dermatome map. The majority of textbooks utilize the map of Foerster, Keegan, and Garrett but don’t include adequate references. Additionally, four textbooks employ maps that do not have citations, such as one that refers to only secondary sources.
Dermatomes are the parts of skin that receives sensory stimulation from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly found, but they tend to be more inferior than horizontally. This is a natural variation and some tissues are covered by more than one dermatome. Furthermore dorsal spinal rootlets could have intrathecal intersegmental anastomoses to sensory neurons from those limbs that are dorsal.
