What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes are important in allowing doctors to develop diagrams of the spine that help in diagnosing. Two maps are widely accepted by medical professionals. These are: the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are commonly used. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.

Dermatomes are skin areas that are attached to a specific nerve bundle. When there is a spinal cord injury, pain may be felt in a dermatome that is controlled by the nerve. The same is true for the pain caused by an outbreak of shingles is felt by specific spinal nerves. If you feel pain or neurological condition involving the dermatome, it is recommended that you visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is supplied by a single spinal nerve. The nerves transmit motor, sensory as well as autonomic information. They form part of the peripheral nervous system, which connects brain and all the body. Dermatomes can get affected because of a spinal injury. When one of these dermatomes gets injured, it is able to be easily treated using a local anesthetic.

The dermatomes of the thoracic region are labeled using letter-number sequences that demonstrate how the region is connected along with the sensor nerve that supplies that region. For instance C1’s spinal nerve doesn’t have a dermatome. However, those spinal nerves that are labeled as C1-C8, while T9 corresponds to the belly button. Dermatomes are layered in vertically on the trunk however, dermatomes on the extremities tend to be in a longitudinal.

Dermatome Map

Dermatome maps are an integral part of textbooks that teach anatomy. The dermatome map is inconsistency both within and inter-textbook. The names are inconsistent and certain textbooks have various maps on different pages. This is especially problematic when the authors of multiple chapters are not unified in their choice of dermatome map. A majority of textbooks employ the Maps of Foerster, Keegan, and Garrett but don’t include proper references. Additionally, four textbooks employ maps with no citations. This includes one that only cites secondary sources.

Dermatomes are the regions of skin that receives sensory input from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to be more inferior than horizontally. This is a natural 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 in Dorsal limbs.
