Dermatome Map Of Head By Annie Campbell University Of Du Flickr – If you have ever wondered how the human dermatome chart is, you’ve come to the right spot. Before we move on to the map, let’s look at the definition of a dermatome. What are the different kinds? And, most importantly, why is it necessary to know about dermatomes in order to know more about how the body works. 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 is a part of your spinal cord. Dermatomes are important in allowing doctors to construct diagrams of the spine that aid in the diagnosis. Two major maps are accepted by medical experts. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still often employed. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas which are connected to a particular nerve. In cases of spinal injury, the pain could be felt in a dermatome which is connected to that nerve. The same is true for the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by the spinal nerve. These nerves relay sensory, motor and autonomic information. They form a part of the peripheral nerve system, which connects brain and rest of the body. A dermatome may be affected by a spinal cord injury. If one of these dermatomes is injured, it can be treated easily with a local anesthetic.
Dermatomes in the thoracic region are labeled with letter-number combinations that show the connection between the area in question and the sensory nerve that is responsible for that area. For example, the C1 spinal nerve does not possess a dermatome, however those spinal nerves that are labeled C1 – C8 and T9 is a reference to the belly button. Dermatomes are layered in horizontally on the trunk, while dermatomes in the extremities are usually linear.
Dermatome Map
The dermatome map is an integral part of textbooks teaching anatomy. But, the map is inconsistency both within and inter-textbook. The names are inconsistent and certain textbooks have different maps on various pages. This can be particularly challenging when the authors of multiple chapters do not agree on the selection of dermatome map. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett but don’t include adequate references. In addition, four textbooks utilize maps that do not have citations, such as one that only cites secondary sources.
Dermatomes are the areas of skin that receives sensory stimulation from the dorsal root of a spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip less inferiorly than horizontally. This is a normal variation and some tissues are covered by more than one dermatome. Additionally dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons that originate from the dorsal parts of the limbs.
