What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes can help doctors to create images of spinal cord that help in diagnosing. Two maps are widely accepted by medical specialists. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s, and are widely used. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas which are connected to a particular nerve. When there is a spinal cord injury, pain may be felt in a dermatome which is surrounded by the nerve. The same is true for the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you experience a nerve pain or neurological problem affecting the dermatome region, you need to consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by a single spinal nerve. These nerves provide motor, sensory, and autonomic information. They form an element of the peripheral nerve system, which connects brain and all the body. A dermatome may get affected because of a spinal lesion. If one of these becomes injured, it can be easily treated with the use of a local anesthetic.
Dermatomes in the thoracic area are marked with letter-number combinations that show how the region is connected as well as the nerve that serves that region. For example, the C1 spinal nerve does not have a dermatome, but all spinal nerves in the region are labeled C1 – C8, while T9 corresponds to the belly button. Dermatomes are layered horizontally on the trunk, those on the extremities tend to be longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks that teach anatomy. But, the map is inconsistency both within and inter-textbook. The name is not consistent and certain textbooks have distinct maps on different pages. This is particularly problematic in the event that the authors of various chapters differ in their choice of dermatome map. Many textbooks use the maps of Foerster, Keegan, and Garrett but do not include adequate references. Moreover, four textbooks use maps without citations, including one that only cites secondary sources.
Dermatomes are the areas of skin that receives sensory innervation from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip less inferiorly than horizontally. This is a normal variation and some tissues may be covered by multiple dermatomes. Also, dorsal spinal rootlets may contain intrathecal intersegmental connections with sensory neurons from the dorsal parts of the limbs.
