What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help doctors to construct models of the cord, which help in diagnosing. Two major maps are regarded as valid by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are frequently utilized. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.

Dermatomes are areas of skin that are linked to a particular nerve bundle. In cases of spinal injuries, pain may be felt in a dermatome which is surrounded by the nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is supplied by the spinal nerve. These nerves relay motor, sensory, as well as autonomic information. They form a part of the peripheral nervous system, that connects the brain to the all the body. A dermatome may suffer from a spinal cord lesion. When one of these dermatomes becomes injured, it could be easily treated using an local anesthetic.

The dermatomes of the thoracic area are marked with letters-numbers that illustrate how the region is connected along with the sensor nerve which supplies the area. For example C1’s spinal nerve doesn’t have a dematome, however all spinal nerves in the region are identified as C1-C8 T9, which corresponds with the belly button. Dermatomes are layered in horizontally on the trunk those in the extremities are usually in a longitudinal.

Dermatome Map

Dermatome maps are one of the common features of textbooks that teach anatomy. But, the map is not uniform both inside and inter-textbook. The name is not consistent and certain textbooks have different maps on different pages. This can be particularly challenging when the authors of several chapters disagree on the choice of dermatome map. Most textbooks use diagrams drawn by Foerster, Keegan, and Garrett but do not include adequate references. In addition, four textbooks utilize maps without citations, including one that cites only secondary sources.

The dermatome is the area of skin that receives sensory innervation from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip less inferiorly than horizontally. This is a normal variation and some tissues are covered by more than one dermatome. Additionally dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons in Dorsal limbs.
