What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the spine. Dermatomes can help physicians to build maps of the spinal cord, which aid in the diagnosis. Two maps are widely accepted by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are frequently utilized. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.

Dermatomes are skin-like areas that are linked to a specific nerve bundle. In cases of spinal cord injury, pain may be felt in a dermatome which is connected to that nerve. Similarly, the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome region, you need to consult a physician.

What are Some Examples of Dermatomes?

Dermatomes are segments of skin that is supplied by a single spinal nerve. The nerves transmit motor, sensory and autonomic signals. They form an element of the peripheral nervous system which connects the brain and all the body. Dermatomes can get affected because of a spinal cord lesion. If one of these dermatomes gets injured, it is able to be treated easily with local anesthetic.

Dermatomes in the thoracic region have been labeled by letter-number combinations, which show the connection between the region along with the sensor nerve that serves that region. For example the C1 spinal nerve doesn’t have a dermatome, but all spinal nerves in the region are labeled C1-C8, while T9 corresponds with the belly button. Dermatomes are laid horizontally on the trunk and dermatomes located on the extremities are typically long.

Dermatome maps are the most common element in textbooks that cover anatomy. However, the dermatome maps is not uniform both inside and inter-textbook. The names are inconsistent, and some textbooks feature different maps on different pages. This is especially problematic when the authors of several chapters disagree on the choice of dermatome maps. Most textbooks use maps of Foerster, Keegan, and Garrett however, they do not provide appropriate references. In addition, four textbooks utilize maps without citations, including one that uses only secondary sources.

Dermatomes are the areas 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 less inferiorly than horizontally. This is a normal variation and some tissue types are covered with more than one. Also dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons in the dorsal limbs.
