Pin On DERMATOMES – If you’ve ever wanted to know how the human dermatome map appears, then you’re at the right spot. Before we move on to this map, lets take a look at what a dermatome is. What are the different kinds? And most importantly, what is the reason to know about dermatomes in order to know more about how the body works. 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 your spinal cord. Dermatomes can help doctors to develop images of spinal cord that aid in the diagnosis. Two major maps are recognized by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain widely used. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are areas of skin that are attached to a specific nerve bundle. In cases of spinal cord injury, the pain could be felt in a dermatome that is innervated by that nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by one spinal nerve. These nerves provide sensory, motor, and autonomic signals. They form a part of the peripheral nervous system, which connects the brain and other parts of the body. A dermatome may become affected due to a spinal cord injury. If one of these dermatomes becomes injured, it could be easily treated with the use of a local anesthetic.
Dermatomes in the thoracic region have been labeled using letter-number sequences that demonstrate the connection between the area and the sensory nerve that is responsible for that area. For instance C1 spinal nerve does not have a dermatome, but the other spinal nerves are labeled C1-C8 T9, which corresponds to belly button. Dermatomes are laid horizontally on the trunk, and dermatomes located in the extremities are usually longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks that cover anatomy. The dermatome map is inconsistent both intra and inter-textbook. The names are inconsistent, and some textbooks feature various maps on different pages. This is particularly problematic when the authors of different chapters do not agree on the selection of dermatome map. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide proper references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that uses only secondary sources.
Dermatomes are the regions of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip lower than horizontally. This is an inherent variation and some tissues are covered by more than one dermatome. Furthermore, dorsal spinal rootlets may contain intrathecal intersegmental connections with sensory neurons in the dorsal parts of the limbs.
