What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes help doctors to construct images of spinal cord, which aid in the diagnosis. Two major maps are accepted by medical professionals. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are commonly used. The trigeminal nerve and the maxillary nerve are the largest dermatomes.

Dermatomes are skin areas that are attached to a particular nerve. When there is a spinal cord injury, the pain could be felt in a dermatome, which is controlled by the nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in particular spinal nerves. If you suffer from discomfort or neurological issue involving the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?

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

The dermatomes of the thoracic region are identified by letter-number combinations, which show the connection between the region along with the sensor nerve that serves that area. For example the C1 spinal nerve doesn’t have a dermatome, but the other spinal nerves are labeled as C1-C8 and T9 refers to belly button. Dermatomes are layered in vertically on the trunk while dermatomes in the extremities are usually in a longitudinal.

Dermatome Map

Dermatome maps are one of the common features of textbooks that cover anatomy. However, the dermatome maps is not consistent both within and inter-textbook. Its naming is inconsistent and some textbooks include various maps on different pages. This is especially problematic when the authors of multiple chapters do not agree on the selection of dermatome map. Many textbooks use the maps of Foerster, Keegan, and Garrett however they don’t provide proper references. Moreover, four textbooks use maps with no citations, and one of them is one that refers to only secondary sources.

The dermatome is the area of skin that receives sensory input from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip more inferiorly than horizontally. This is a normal variation and some tissues have more than one. Additionally dorsal spinal rootlets could contain intrathecal intersegmental connections with sensory neurons of the dorsal parts of the limbs.
