Before we look at an image, it’s important to look at what a dermatome is. What are the different types? And, most importantly, why is it essential to be aware of dermatomes order to comprehend how the body works. 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 spine. Dermatomes help physicians to build models of the cord, which are useful for diagnosis. Two maps are widely accepted by medical experts. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still frequently utilized. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas which are connected to a specific nerve. In cases of spinal injury, the pain could be felt in a dermatome, which is surrounded by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin supplied by the spinal nerve. These nerves provide sensory, motor, and autonomic signals. They form an element of the peripheral nerve system, that connects the brain to the other parts of the body. Dermatomes can get affected because of a spinal cord lesion. If one of these becomes injured, it can be easily treated with the use of a local anesthetic.
The dermatomes of the thoracic region are identified with letter-number combinations that show the connection between the region in question and the sensory nerve that serves this area. For example, the C1 spinal nerve doesn’t have a dematome, however the other spinal nerves are labeled as C1-C8 T9, which corresponds to belly button. Dermatomes are layered vertically on the trunk and dermatomes located on the extremities tend to be in a longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks that teach anatomy. But, the map is not consistent both within and inter-textbook. The name is not consistent as are some textbooks that have different maps on different pages. This can be particularly challenging in the event that the authors of various chapters do not agree on the selection of dermatome map. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide appropriate references. Additionally, four textbooks employ maps without citations, including one that uses only secondary sources.
The dermatome is the area of skin that receives sensory input from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip lower than horizontally. This is a natural variation and certain tissues may be covered by multiple dermatomes. Additionally dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons from those limbs that are dorsal.
