Before we move on to our map, we’ll look at what a dermatome actually is. What are the different kinds? The most important thing is why is it essential to learn about dermatomes in order to know more about our body. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help physicians to build models of the cord that are useful for diagnosis. Two major maps are recognized by medical specialists. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still widely utilized. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that are attached to a specific nerve bundle. In the case of spinal cord injury, pain can be felt in a dermatome, which is connected to that nerve. The same is true for the pain caused by shingles outbreaks is felt by specific spinal nerves. If you experience a neurologic condition or pain that involves the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin supplied by the spinal nerve. The nerves transmit sensory, motor as well as autonomic information. They form part of the peripheral nerve system that connects the brain to the rest 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 using an local anesthetic.
The dermatomes of the thoracic area are marked using letter-number sequences that demonstrate the connection between the region along with the sensor nerve that is responsible for this area. For instance C1’s spinal nerve does not possess a dermatome, however all spinal nerves in the region are labeled C1 – C8 and T9 refers with the belly button. Dermatomes are layered horizontally along the trunk, those in the extremities are usually in a longitudinal.
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. Its name isn’t consistent, and some textbooks feature distinct maps on different pages. This is particularly problematic when the authors of several chapters are not unified in their choice of dermatome map. Many textbooks use the map of Foerster, Keegan, and Garrett but don’t include the proper references. In addition, four textbooks utilize 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 less inferiorly than horizontally. This is an inherent variation and some tissues have more than one. Also dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons from the dorsal limbs.
