Dermatome Map Upper Body – If you have ever wondered what the human dermatome map is, you’ve come to the right place. Before we move on to an image, it’s important to discuss what a dermatome is. What are the different kinds? And, most importantly, why is it necessary to learn about dermatomes in order to better understand the human body. Continue reading to learn more. You might be amazed! 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 can help doctors to develop diagrams of the spine, which can be useful in diagnosing. Two major maps are regarded as valid by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still frequently utilized. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.

Dermatomes are skin-like areas that are linked to a specific nerve bundle. In cases of spinal injuries, pain may be felt in a dermatome which is innervated by that nerve. Similarly, the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you suffer from pain or neurological condition involving the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin that is provided by the spinal nerve. These nerves carry motor, sensory and autonomic messages. They form a part of the peripheral nervous system which connects brain and rest of the body. Dermatomes can be affected by a spinal lesion. If one of these is injured, it can be easily treated with the use of a local anesthetic.

The dermatomes of the thoracic region are labeled using letter-number sequences that demonstrate the connection between the area as well as the nerve that serves that area. For instance the C1 spinal nerve does not possess a dermatome, however those spinal nerves that are identified as C1-C8, while T9 corresponds to the belly button. Dermatomes are layered horizontally on the trunk, those on the extremities tend to be longitudinal.

Dermatome Map

The dermatome map is the most common element in textbooks that cover anatomy. But, the map is not consistent both within and inter-textbook. Its naming is inconsistent as are some textbooks that have different maps on various pages. This is particularly problematic when the authors of different chapters do not agree on the selection of dermatome maps. Most textbooks use Maps of Foerster, Keegan, and Garrett but don’t include the proper references. Additionally, four textbooks employ maps with no citations. This includes one that refers to only secondary sources.

Dermatomes are the areas of skin that receives sensory input from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly found, but they tend to dip less inferiorly than horizontally. This is a natural variation and certain tissue types are covered with more than one. In addition to this dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons that originate from the dorsal limbs.
