Dermatomes Neurology Medbullets Step 1 – If you’ve ever wondered how the human dermatome chart appears, then you’re at the right place. Before we go to the map, let’s talk about what a dermatome actually is. What are the various types? And most importantly, why is it important to know about dermatomes in order to better understand your body. Read on to find out more. You may be surprised! Here are some examples of dermatomes.
What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes can help doctors to create images of spinal cord that help in diagnosing. Two maps are widely accepted by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain widely employed. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.
Dermatomes are areas of skin that are attached to a specific nerve. In cases of spinal injuries, pain may be felt in a dermatome which is connected to that nerve. Similar to the pain that is caused by shingles outbreaks can be felt on specific spinal nerves. If you are experiencing pain or neurological condition involving the dermatome, it is recommended that you visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is provided by one spinal nerve. These nerves provide sensory, motor, as well as autonomic information. They form an element of the peripheral nervous system which connects the brain with the all the body. A dermatome may get affected because of a spinal cord injury. If one of these 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 connection between the area in question and the sensory nerve that supplies this area. For example the C1 spinal nerve does not have a dermatome, but those spinal nerves that are identified as C1-C8, while T9 corresponds to the belly button. Dermatomes are layered in vertically on the trunk those on the extremities are typically longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks that teach anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. The names are inconsistent as are some textbooks that have different maps on different pages. This is particularly problematic when the authors of multiple chapters are not unified in their choice of dermatome map. Most textbooks use map of Foerster, Keegan, and Garrett however they don’t provide proper references. In addition, four textbooks utilize maps that do not have citations, such as one that uses only secondary sources.
The dermatome is the area of the skin that receives sensory information from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip more inferiorly than horizontally. This is a natural variation and some tissues have more than one. Also dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons of the dorsal parts of the limbs.
