What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that covers your spinal cord. Dermatomes can help doctors to create diagrams of the spine that help in diagnosing. Two major maps are regarded as valid by medical professionals. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are frequently employed. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.

Dermatomes are skin regions that are attached to a particular nerve bundle. When there is a spinal cord injury, pain can be felt in a dermatome that is surrounded by the nerve. The same is true for the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you are experiencing nerve pain or neurological problem affecting the dermatome, it is recommended that you see a doctor.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin that is supplied by the spinal nerve. These nerves relay sensory, motor, as well as autonomic information. They form an element of the peripheral nervous system that connects the brain to the other parts of the body. Dermatomes can get affected because of a spinal cord lesion. If one of these dermatomes gets injured, it is able to be easily treated using an local anesthetic.

The dermatomes of the thoracic region are labeled with letters-numbers that illustrate the relationship between the area along with the sensor nerve that supplies this area. For example C1’s spinal nerve does not have a dematome, however others spinal nerves have been labeled C1-C8 and T9 is a reference to belly button. Dermatomes are laid horizontally along the trunk, and dermatomes located in the extremities are usually in a longitudinal.

Dermatome Map

The dermatome map is the most common element in textbooks teaching anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. Its name isn’t consistent as are some textbooks that have distinct maps on different pages. This is especially problematic in the event that the authors of various chapters disagree on the choice of dermatome maps. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide proper references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that only cites secondary sources.

The dermatome is the area of the skin that receives sensory information from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly found, but they tend to dip less inferiorly than horizontally. This is a normal variation and certain tissues may be covered by multiple dermatomes. Additionally dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal limbs.
