Before we go to an image, it’s important to look at what a dermatome actually is. What are the different types? And, most importantly, why is it important to understand dermatomes in order to know more about how the body works. 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 is a part of the cord of the spinal. Dermatomes play a crucial role in allowing doctors to construct models of the cord that help in diagnosing. Two major maps are regarded as valid by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still commonly used. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that connect to a specific nerve bundle. When there is a spinal cord injury, pain may be felt in a dermatome, which is connected to that nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in specific spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin supplied by one spinal nerve. These nerves provide sensory, motor and autonomic information. They form an element of the peripheral nervous system which connects the brain and other parts of the body. Dermatomes can suffer from a spinal cord lesion. If one of these dermatomes gets injured, it is able to be treated easily with local anesthetic.
The dermatomes of the thoracic region have been labeled by letter-number combinations, which show the relationship between the area and the sensory nerve that serves the area. For instance C1 spinal nerve does not have a dematome, however others spinal nerves have been labeled as C1-C8 and T9 refers with the belly button. Dermatomes are layered in horizontally along the trunk, and dermatomes located that are located on the extremities are generally linear.
Dermatome Map
The dermatome map is the most common element in textbooks teaching anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. Its name isn’t consistent and some textbooks include different maps on various pages. This is particularly problematic when the authors of several chapters do not agree on the selection of dermatome map. Most textbooks use maps of Foerster, Keegan, and Garrett however, they do not provide appropriate references. In addition, four textbooks utilize maps with no citations. This includes one that only cites secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly found, but they tend to dip more inferiorly than horizontally. This is a natural variation and some tissues may be covered by multiple dermatomes. Furthermore dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons in Dorsal limbs.
