What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes play a crucial role in allowing doctors to construct models of the cord, which aid in the diagnosis. Two major maps are regarded as valid by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain frequently used. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.

Dermatomes are skin areas which are connected to a specific nerve. In the case of spinal cord injury, the pain could be felt in a dermatome which is surrounded by the nerve. Similarly, the pain caused by shingles outbreaks can be felt in specific spinal nerves. If you suffer from discomfort or neurological issue involving the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin supplied by one spinal nerve. These nerves provide motor, sensory, and autonomic information. They form a part of the peripheral nerve system, that connects the brain to the all the body. A dermatome may suffer from a spinal cord lesion. If one of these becomes injured, it can be easily treated using local anesthetic.

The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate the connection between the region as well as the nerve that supplies that area. For instance C1 spinal nerve doesn’t have a dematome, however others spinal nerves have been labeled C1 – C8, while T9 corresponds to the belly button. Dermatomes are laid vertically on the trunk and dermatomes located in the extremities are usually in a longitudinal.

Dermatome Map

Dermatome maps are a common feature of textbooks that cover anatomy. The dermatome map is inconsistent both intra and inter-textbook. The names are inconsistent and certain textbooks have different maps on various pages. This can be particularly challenging in the event that the authors of various chapters disagree on the choice of dermatome maps. The majority of textbooks utilize the maps of Foerster, Keegan, and Garrett but don’t include the proper references. In addition, four textbooks utilize maps that do not have citations, such as one that refers to 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 evenly located, but they tend to dip less inferiorly than horizontally. This is a natural variation and some tissues are covered by more than one dermatome. Additionally, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons in Dorsal limbs.
