What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes are important in allowing doctors to construct models of the cord, which are useful for diagnosis. Two major maps are recognized by medical specialists. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still widely utilized. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.

Dermatomes are skin-like areas that are linked to a specific nerve bundle. In cases of spinal cord injuries, pain may be experienced in a dermatome that is controlled by the nerve. In the same way, the pain triggered by an outbreak of shingles is felt by specific spinal nerves. If you suffer from nerve pain or neurological problem affecting the dermatome region, you need to consult with a physician.

What are Some Examples of Dermatomes?

A dermatome is a segment of skin that is provided by a single spinal nerve. The nerves transmit sensory, motor, as well as autonomic information. They form a part of the peripheral nervous system which connects brain and all the body. A dermatome may be affected by a spinal cord lesion. If one of these dermatomes is injured, it can be treated easily with a local anesthetic.

Dermatomes in the thoracic area are marked by letter-number combinations, which show how the region is connected as well as the nerve which supplies the area. For instance C1’s spinal nerve does not have a dematome, however those spinal nerves that are labeled as C1-C8 T9, which corresponds to belly button. Dermatomes are layered horizontally along the trunk, however, dermatomes on the extremities are typically in a longitudinal.

Dermatome Map

Dermatome maps are the most common element in textbooks that teach anatomy. The dermatome map is inconsistency both within and inter-textbook. The name is not consistent, and some textbooks feature different maps on various pages. This is particularly problematic when the authors of several chapters are not unified in their choice of dermatome map. Many textbooks use the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide proper references. Moreover, four textbooks use maps with no citations. This includes one that refers to only secondary sources.

Dermatomes are the parts of skin that receives sensory innervation from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip lower than horizontally. This is a normal variation and certain tissues are covered by more than one dermatome. In addition to this dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons of the dorsal parts of the limbs.
