Before we look at the map, let’s look at the definition of a dermatome. What are the various types? And, most importantly, what is the reason 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?
“dermatome,” or “dermatome” refers to a tissue that is a part of the spine. Dermatomes help doctors to create maps of the spinal cord, which aid in the diagnosis. Two major maps are regarded as valid by medical professionals. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still frequently employed. The trigeminal and maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that are linked to a specific nerve bundle. In cases of spinal cord injury, pain may be experienced in a dermatome that is connected to that nerve. Similarly, the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you experience a nerve pain or neurological problem affecting the dermatome, it is recommended that you see a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is supplied by a single spinal nerve. These nerves provide sensory, motor and autonomic signals. They form a part of the peripheral nervous system which connects the brain and rest of the body. A dermatome may become affected due to a spinal lesion. When one of these dermatomes gets injured, it is able to be easily treated with the use of a local anesthetic.
The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate how the region is connected and the sensory nerve that supplies the area. For instance C1’s spinal nerve does not have a dematome, however all spinal nerves in the region are labeled as C1-C8 and T9 refers with the belly button. Dermatomes are laid horizontally on the trunk while dermatomes in the extremities are usually long.
Dermatome Map
The dermatome map is the most common element in textbooks that teach anatomy. The dermatome map is inconsistency both within and inter-textbook. The names are inconsistent as are some textbooks that have different maps on various pages. This can be particularly challenging in the event that the authors of various chapters are not unified in their choice of dermatome maps. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett but don’t include proper references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that only cites secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation from the dorsal root of one spinal nerve. Dermatomes aren’t evenly located, but they tend to dip more inferiorly than horizontally. This is a natural variation and certain tissues are covered by more than one dermatome. Furthermore, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal parts of the limbs.
