Facial Nerve Dermatomes Quiz – If you’ve ever thought about what the human dermatome map looks, you’ve come to the right place. Before we get to an image, it’s important to take a look at what a dermatome is. What are the different types? The most important thing is why is it important to know about dermatomes in order to understand our body. 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 spinal cord. Dermatomes play a crucial role in allowing doctors to construct images of spinal cord, which can be useful in diagnosing. Two major maps are recognized by medical professionals. There is the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are widely utilized. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.
Dermatomes are skin-like areas that connect to a particular nerve. In cases of spinal cord injury, pain may be felt in a dermatome which is surrounded by the nerve. In the same way, the pain triggered by shingles outbreaks can be felt on specific spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome region, you need to consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by one spinal nerve. These nerves carry motor, sensory as well as autonomic information. They form an element of the peripheral nervous system which connects the brain with the rest of the body. Dermatomes can be affected by a spinal lesion. If one of these becomes injured, it could be easily treated with local anesthetic.
Dermatomes in the thoracic region are identified with letter-number combinations that show the connection between the region in question and the sensory nerve that is responsible for the area. For instance the C1 spinal nerve does not have a dermatome. However, the other spinal nerves are labeled C1-C8 and T9 refers to belly button. Dermatomes are laid vertically on the trunk while dermatomes on the extremities are typically longitudinal.
Dermatome Map
The dermatome map is a common feature of textbooks that cover anatomy. However, the dermatome maps is not consistent both within and inter-textbook. The name is not consistent, and some textbooks feature different maps on different pages. This is particularly problematic when the authors of multiple chapters do not agree on the selection of dermatome map. Most textbooks use map of Foerster, Keegan, and Garrett however they don’t provide adequate references. In addition, four textbooks utilize maps without citations, including one that only cites secondary sources.
Dermatomes are the areas of skin that receives sensory innervation from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly situated, but they tend to dip less inferiorly than horizontally. This is a natural variation, and some tissue types are covered with more than one. Additionally, dorsal spinal rootlets may contain intrathecal intersegmental connections with sensory neurons in those limbs that are dorsal.
