What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes help doctors to construct diagrams of the spine, which are useful for diagnosis. Two major maps are regarded as valid by medical experts. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are commonly employed. The trigeminal nerve and the maxillary nerve are the largest dermatomes.
Dermatomes are skin-like areas that connect to a particular nerve bundle. In cases of spinal cord injury, the pain could be felt in a dermatome, which is controlled by the nerve. In the same way, the pain triggered by shingles outbreaks can be felt in specific spinal nerves. If you feel neurologic condition or pain that involves the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by a single spinal nerve. The nerves transmit sensory, motor, and autonomic information. They form a part of the peripheral nervous system, that connects the brain to the other parts of the body. Dermatomes can get affected because of a spinal cord lesion. When one of these dermatomes becomes injured, it could be easily treated with an local anesthetic.
The dermatomes of the thoracic region are labeled using letter-number sequences that demonstrate the connection between the area in question and the sensory nerve that serves this area. For example, the C1 spinal nerve doesn’t have a dermatome, but those spinal nerves that are labeled C1-C8 T9, which corresponds to the belly button. Dermatomes are laid horizontally on the trunk while dermatomes that are located on the extremities are generally in a longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks that teach anatomy. The dermatome map is inconsistent both intra and inter-textbook. The name is not consistent as are some textbooks that have different maps on different pages. This is particularly problematic when the authors of different chapters disagree on the choice of dermatome map. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett however they don’t provide proper references. Additionally, four textbooks employ maps with no citations. This includes one that refers to only secondary sources.
Dermatomes are the parts of skin that receives sensory stimulation from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip more inferiorly than horizontally. This is a normal variation and certain tissues have more than one. Also dorsal spinal rootlets could contain intrathecal intersegmental connections with sensory neurons from those limbs that are dorsal.
