Before we look at this map, lets talk about what is a dermatome. What are the various types? The most important thing is why is it necessary to be aware of dermatomes order to comprehend the human body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.
What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes are important in allowing doctors to create diagrams of the spine that aid in the diagnosis. Two major maps are accepted by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain commonly used. The trigeminal nerve , as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are skin areas which are connected to a specific nerve bundle. In cases of spinal injury, pain can be felt in a dermatome, which is connected to that nerve. Similar to the pain that is caused by shingles outbreaks can be felt in specific spinal nerves. If you feel nerve pain or neurological problem affecting the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by a single spinal nerve. The nerves transmit motor, sensory, and autonomic signals. They form an element of the peripheral nervous system, that connects the brain to the all the body. A dermatome may become affected due to a spinal cord lesion. If one of these dermatomes gets injured, it is able to be easily treated with an local anesthetic.
Dermatomes in the thoracic region have been labeled with letters-numbers that illustrate the relationship between the area as well as the nerve that serves this area. For example C1 spinal nerve does not possess a dermatome, however all spinal nerves in the region are labeled C1-C8 T9, which corresponds to belly button. Dermatomes are layered in horizontally on the trunk, however, dermatomes on the extremities are typically long.
Dermatome Map
The dermatome map is the most common element in textbooks that cover anatomy. The dermatome map is not consistent both within and inter-textbook. The name is not consistent and certain textbooks have different maps on different pages. This is particularly problematic in the event that the authors of various chapters do not agree on the selection of dermatome map. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett but do not include proper references. In addition, four textbooks utilize maps without citations, including one that cites only secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation from the dorsal root of one spinal nerve. Dermatomes aren’t evenly found, but they tend to be more inferior than horizontally. This is a normal variation and some tissues have more than one. Also, dorsal spinal rootlets may contain intrathecal intersegmental connections with sensory neurons of those limbs that are dorsal.
