What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes play a crucial role in allowing doctors to construct images of spinal cord that aid in the diagnosis. Two major maps are regarded as valid by medical professionals. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain commonly utilized. The trigeminal and maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that connect to a specific nerve bundle. In the case of spinal cord injury, pain can be felt in a dermatome which is connected to that nerve. Similar to the pain that is caused by shingles outbreaks can be felt in particular spinal nerves. If you experience a 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 supplied by a single spinal nerve. These nerves provide sensory, motor as well as autonomic information. They form a part of the peripheral nervous system, which connects brain and other parts of the body. Dermatomes can get affected because of a spinal cord injury. If one of these becomes injured, it can be treated easily with an local anesthetic.
Dermatomes in the thoracic region have been labeled by letter-number combinations, which show how the region is connected in question and the sensory nerve that serves that region. For example 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 layered horizontally on the trunk, and dermatomes located in the extremities are usually longitudinal.
Dermatome Map
The dermatome map is the most common element in textbooks that teach anatomy. However, the dermatome map is inconsistency both within and inter-textbook. The names are inconsistent, and some textbooks feature 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 map. Most textbooks use map of Foerster, Keegan, and Garrett however, they do not provide adequate references. Moreover, four textbooks use maps without citations, including one that refers to only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to be more inferior than horizontally. This is a natural variation, and certain tissues may be covered by multiple dermatomes. In addition to this dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons that originate from the dorsal parts of the limbs.
