What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of the spine. Dermatomes can help doctors to develop maps of the spinal cord that aid in the diagnosis. Two major maps are recognized by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are commonly used. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.
Dermatomes are areas of skin that are linked to a particular nerve bundle. In cases of spinal cord injury, pain may be felt in a dermatome which is connected to that nerve. In the same way, the pain triggered by shingles outbreaks can be felt on specific spinal nerves. If you experience a neurologic condition or pain that involves the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by one spinal nerve. The nerves transmit sensory, motor and autonomic signals. They form a part of the peripheral nerve system that connects the brain to the all the body. A dermatome may suffer from a spinal lesion. If one of these dermatomes becomes injured, it can be easily treated using local anesthetic.
Dermatomes in the thoracic area are marked with letter-number combinations that show the connection between the area as well as the nerve that serves this area. For instance the C1 spinal nerve does not have a dermatome, but others spinal nerves have been labeled C1-C8 and T9 refers with the belly button. Dermatomes are layered horizontally along the trunk, and dermatomes located on the extremities are typically long.
Dermatome Map
Dermatome maps are the most common element in textbooks that cover anatomy. The dermatome map is not uniform both inside and inter-textbook. The name is not consistent and certain textbooks have various maps on different pages. This is especially problematic in the event that the authors of various chapters disagree on the choice of dermatome maps. The majority of textbooks utilize the map of Foerster, Keegan, and Garrett however they don’t provide adequate references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the parts of skin that receives sensory stimulation from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip more inferiorly than horizontally. This is a normal variation and some tissues may be covered by multiple dermatomes. In addition to this dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons that originate from Dorsal limbs.
