What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the spine. Dermatomes help doctors to construct diagrams of the spine that are useful for diagnosis. Two major maps are recognized by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are widely utilized. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.

Dermatomes are skin areas that are attached to a particular nerve bundle. In cases of spinal injuries, pain may be felt in a dermatome that is innervated by that nerve. The same is true for the pain caused by shingles outbreaks is felt by specific spinal nerves. If you experience a pain or neurological condition involving the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is provided by the spinal nerve. The nerves transmit motor, sensory and autonomic signals. They form an element of the peripheral nerve system which connects the brain with the rest of the body. Dermatomes can suffer from a spinal lesion. If one of these gets injured, it is able to be easily treated with a local anesthetic.

Dermatomes in the thoracic area are marked with letters-numbers that illustrate the relationship between the area in question and the sensory nerve that serves the area. For example C1’s spinal nerve doesn’t possess a dermatome, however those spinal nerves that are labeled C1-C8 and T9 refers to the belly button. Dermatomes are laid horizontally on the trunk and dermatomes located on the extremities are typically longitudinal.

Dermatome Map

The dermatome map is a common feature of textbooks that teach anatomy. However, the dermatome maps is not uniform both inside and inter-textbook. Its naming is inconsistent, and some textbooks feature different maps on different pages. This can be particularly challenging when the authors of several chapters disagree on the choice of dermatome maps. The majority of textbooks utilize the maps of Foerster, Keegan, and Garrett but do not include the proper references. In addition, four textbooks utilize maps with no citations, and one of them is one that refers to only secondary sources.

Dermatomes are the areas of skin that receives sensory innervation from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly located, but they tend to dip lower than horizontally. This is a natural variation, and some tissues may be covered by multiple dermatomes. Additionally dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons of the dorsal parts of the limbs.
