Paediatric Neurological Examination OSCE Guide Geeky Medics – If you’ve ever thought about what the human dermatome’s map will look, you’re in the right spot. Before we look at the map, let’s talk about what a dermatome is. What are the various types? Most importantly, what is the reason to learn about dermatomes in order to comprehend our body. Read on to find out more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes are important in allowing doctors to develop diagrams of the spine, which help in diagnosing. Two maps are widely accepted by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still often utilized. The trigeminal nerve , as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin regions which are connected to a particular nerve. In the case of spinal cord injury, pain may 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 on specific spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by the spinal nerve. These nerves provide sensory, motor, and autonomic messages. They form a part of the peripheral nervous system, which connects the brain with the all the body. Dermatomes can get affected because of a spinal cord injury. If one of these gets injured, it is able to be easily treated with an local anesthetic.
The dermatomes of the thoracic region are identified with letters-numbers that illustrate the relationship between the area in question and the sensory nerve that supplies that area. For instance C1 spinal nerve doesn’t possess a dermatome, however those spinal nerves that are labeled C1 – C8, while T9 corresponds to the belly button. Dermatomes are layered in vertically on the trunk however, dermatomes that are located on the extremities are generally long.
Dermatome Map
Dermatome maps are one of the common features of textbooks that teach anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. The names are inconsistent and some textbooks include different maps on various pages. This is particularly problematic when the authors of several chapters do not agree on the selection of dermatome maps. The majority of textbooks utilize the map of Foerster, Keegan, and Garrett but do not include the proper references. Furthermore, four textbooks make use of maps without citations, including one that cites only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal root of one spinal nerve. The dermatomes are not uniformly located, but they tend to dip more inferiorly than horizontally. This is a normal variation and some tissues may be covered by multiple dermatomes. Also dorsal spinal rootlets could have intrathecal intersegmental anastomoses to sensory neurons that originate from those limbs that are dorsal.
