Sensory Dermatome Map – If you’ve ever thought about what the human dermatome map will look, you’re in the right place. Before we get to the map, let’s talk about what is a dermatome. What are the different kinds? And, most importantly, what is the reason to learn about dermatomes in order to better understand how the body works. Continue reading to learn more. You may 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 play a crucial role in allowing doctors to construct diagrams of the spine, which are useful for diagnosis. Two major maps are accepted by medical professionals. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are often used. The trigeminal and maxillary nerves are the two largest dermatomes.

Dermatomes are skin areas that connect to a specific nerve. In the case of spinal cord injury, pain may be felt in a dermatome that is innervated by that nerve. Similar to the pain that is caused by shingles outbreaks can be felt in particular spinal nerves. If you experience a nerve pain or neurological problem affecting the dermatome region, you need to consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are segments of skin that is provided by one spinal nerve. The nerves transmit motor, sensory, as well as autonomic information. They form a part of the peripheral nervous system, which connects the brain and rest of the body. A dermatome may get affected because of a spinal cord lesion. If one of these gets injured, it is able to be treated easily with an local anesthetic.

The dermatomes of the thoracic area are marked by letter-number combinations, which show the relationship between the area as well as the nerve which supplies this area. For instance the C1 spinal nerve doesn’t have a dermatome. However, the other spinal nerves are labeled as C1-C8, while T9 corresponds to belly button. Dermatomes are laid horizontally on the trunk, while dermatomes that are located on the extremities are generally long.

Dermatome Map

Dermatome maps are one of the common features of textbooks that cover anatomy. The dermatome map is not uniform both inside and inter-textbook. The names are inconsistent and certain textbooks have various maps on different pages. This is particularly problematic when the authors of multiple chapters disagree on the choice of dermatome map. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide adequate references. Moreover, four textbooks use maps with no citations, and one of them is one that only cites secondary sources.

Dermatomes are the regions of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly found, but they tend to dip more inferiorly than horizontally. This is a natural variation, and some tissues have more than one. Additionally dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons from Dorsal limbs.
