Dermatomes Of The Body Poster – If you’ve ever thought about what the human dermatome map looks, you’ve come to the right place. Before we go to our map, we’ll take a look at what a dermatome is. What are the different kinds? And most importantly, why is it important to learn about dermatomes in order to understand your body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers your spinal cord. Dermatomes play a crucial role in allowing doctors to construct maps of the spinal cord, which are useful for diagnosis. Two major maps are accepted by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still commonly used. The trigeminal and maxillary nerves are the two largest dermatomes.
Dermatomes are skin regions that connect to a specific nerve bundle. In cases of spinal injury, pain can be experienced in a dermatome that is controlled by the nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome region, you need to consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by a single spinal nerve. These nerves relay motor, sensory as well as autonomic information. They form part of the peripheral nerve system, which connects the brain with the other parts of the body. Dermatomes can suffer from a spinal lesion. If one of these becomes injured, it could be treated easily with an local anesthetic.
The dermatomes of the thoracic region have been labeled with letter-number combinations that show the relationship between the area in question and the sensory nerve that supplies this area. For instance the C1 spinal nerve does not possess a dermatome, however those spinal nerves that are labeled as C1-C8 T9, which corresponds to belly button. Dermatomes are laid horizontally along the trunk, those on the extremities are typically in a longitudinal.
Dermatome Map
Dermatome maps are an integral part of textbooks that cover anatomy. However, the dermatome maps is not consistent both within and inter-textbook. The names are inconsistent, and some textbooks feature different maps on various pages. This is especially problematic when the authors of different chapters do not agree on the selection of dermatome map. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett but do not include proper references. Additionally, four textbooks employ maps with no citations. This includes one that uses only secondary sources.
The dermatome is the area of skin that receives sensory input from the dorsal root of one spinal nerve. The dermatomes are not uniformly situated, but they tend to dip more inferiorly than horizontally. This is an inherent variation and some tissue types are covered with more than one. Additionally dorsal spinal nerve roots may contain intrathecal intersegmental connections with sensory neurons in the dorsal parts of the limbs.
