What is a Dermatome?

The term “dermatome” refers to a tissue that covers your spinal cord. Dermatomes are important in allowing physicians to build images of spinal cord, which are useful for diagnosis. Two major maps are accepted by medical specialists. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s, and are commonly employed. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.

Dermatomes are areas of skin that are linked to a specific nerve bundle. In cases of spinal injury, pain may be felt in a dermatome which is controlled by the nerve. The same is true for the pain caused by an outbreak of shingles is felt by specific spinal nerves. If you feel discomfort or neurological issue involving the dermatome, you should consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is provided by the spinal nerve. These nerves carry sensory, motor, and autonomic signals. They form a part of the peripheral nervous system which connects the brain and all the body. Dermatomes can suffer from a spinal lesion. If one of these dermatomes is injured, it can be easily treated using the use of a local anesthetic.

The dermatomes of the thoracic region are labeled with letters-numbers that illustrate the connection between the area and the sensory nerve that supplies that area. For instance C1’s spinal nerve does not have a dermatome. However, those spinal nerves that are labeled C1-C8 and T9 refers with the belly button. Dermatomes are layered in vertically on the trunk however, dermatomes on the extremities are typically longitudinal.

Dermatome Map

Dermatome maps are the most common element in textbooks teaching anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. The names are inconsistent, and some textbooks feature distinct maps on different pages. This is particularly problematic when the authors of multiple chapters do not agree on the selection of dermatome maps. Many textbooks use the map of Foerster, Keegan, and Garrett however, they do not provide proper references. Moreover, four textbooks use maps with no citations. This includes one that cites only secondary sources.

The dermatome is the area of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip lower than horizontally. This is a normal variation and some tissue types are covered with more than one. Also, dorsal spinal rootlets may have intrathecal intersegmental anastomoses with sensory neurons that originate from the dorsal limbs.
