Neurology Shoulder Complex – If you’ve ever thought about how the human dermatome chart appears, then you’re at the right place. Before we get to this map, lets take a look at what a dermatome is. What are the various types? And most importantly, why is it necessary to understand dermatomes in order to understand your body. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes are important in allowing doctors to develop models of the cord that help in diagnosing. Two major maps are recognized by medical experts. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and remain often utilized. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin areas which are connected to a specific nerve bundle. In cases of spinal injuries, pain may be felt in a dermatome, which is controlled by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you are experiencing nerve pain or neurological problem affecting the dermatome, you should consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by a single spinal nerve. These nerves carry sensory, motor, and autonomic signals. They form a part of the peripheral nervous system that connects the brain to the all the body. Dermatomes can suffer from a spinal cord lesion. If one of these becomes injured, it could be easily treated using an local anesthetic.
The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate the relationship between the area and the sensory nerve that serves 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 is a reference to the belly button. Dermatomes are laid horizontally on the trunk, those in the extremities are usually in a longitudinal.
Dermatome Map
The dermatome map is the most common element in textbooks that cover anatomy. But, the map is not uniform both inside and inter-textbook. Its name isn’t consistent, and some textbooks feature various maps on different pages. This can be particularly challenging in the event that the authors of various chapters do not agree on the selection of dermatome map. A majority of textbooks employ the map of Foerster, Keegan, and Garrett however, they do not provide proper references. Moreover, four textbooks use maps with no citations, and one of them is one that only cites secondary sources.
The dermatome is the area of skin that receives sensory innervation from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly situated, but they tend to dip less inferiorly than horizontally. This is a normal variation and some tissue types are covered with more than one. Additionally dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons in the dorsal parts of the limbs.
