What is a Dermatome?

The term “dermatome” refers to a tissue that covers the spine. Dermatomes can help doctors to develop images of spinal cord, which aid in the diagnosis. Two maps are widely accepted by medical professionals. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and remain widely utilized. The trigeminal and maxillary nerves are the two largest dermatomes.

Dermatomes are skin-like areas that are attached to a particular nerve bundle. When there is a spinal cord injury, pain may be experienced in a dermatome that is surrounded by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you feel nerve pain or neurological problem affecting the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?

A dermatome is a segment of skin that is provided by only one spinal nerve. These nerves relay motor, sensory and autonomic information. They form an element of the peripheral nervous system, which connects brain and other parts of the body. Dermatomes can become affected due to a spinal cord injury. If one of these is injured, it can be easily treated with local anesthetic.

Dermatomes in the thoracic area are marked with letters-numbers that illustrate the relationship between the area along with the sensor nerve which supplies this area. For instance C1’s spinal nerve doesn’t have a dermatome. However, those spinal nerves that are identified as C1-C8 and T9 is a reference to belly button. Dermatomes are layered in horizontally on the trunk, those on the extremities are typically linear.

Dermatome Map

Dermatome maps are the most common element in textbooks teaching anatomy. However, the dermatome map is inconsistency both within and inter-textbook. Its naming is inconsistent and certain textbooks have distinct maps on different pages. This is particularly problematic when the authors of different chapters differ in their choice of dermatome map. Most textbooks use maps of Foerster, Keegan, and Garrett however they don’t provide the proper references. Furthermore, four textbooks make use of maps that do not have citations, such as one that uses 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 evenly located, but they tend to be more inferior than horizontally. This is an inherent variation and some tissues may be covered by multiple dermatomes. In addition to this, dorsal spinal rootlets may have intrathecal intersegmental anastomoses with sensory neurons of the dorsal limbs.
