What is a Dermatome?

The term “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes play a crucial role in allowing doctors to develop models of the cord that aid in the diagnosis. Two maps are widely accepted by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain frequently utilized. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.

Dermatomes are skin areas that are linked to a particular nerve bundle. In cases of spinal injury, the pain could be felt in a dermatome, which 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 are experiencing nerve pain or neurological problem affecting the dermatome area, you must 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. These nerves relay sensory, motor and autonomic messages. They form a part of the peripheral nervous system which connects the brain with the other parts of the body. A dermatome may get affected because of a spinal injury. When one of these dermatomes gets injured, it is able to be easily treated with the use of a local anesthetic.

Dermatomes in the thoracic region have been labeled by letter-number combinations, which show the connection between the area along with the sensor nerve that serves the area. For example the C1 spinal nerve doesn’t have a dermatome, but the other spinal nerves are labeled C1 – C8 T9, which corresponds to the belly button. Dermatomes are layered in horizontally on the trunk those on the extremities are typically in a longitudinal.

Dermatome Map

The dermatome map is an integral part of textbooks that teach anatomy. The dermatome map is inconsistent both intra and inter-textbook. The names are inconsistent and some textbooks include various maps on different pages. This can be particularly challenging in the event that the authors of various chapters differ in their choice of dermatome maps. Most textbooks use diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide adequate references. In addition, four textbooks utilize maps without citations, including one that only cites secondary sources.

Dermatomes are the areas of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip more inferiorly than horizontally. This is a natural variation, and certain tissue types are covered with more than one. Also, dorsal spinal rootlets may have intrathecal intersegmental anastomoses with sensory neurons of Dorsal limbs.
