What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes help doctors to construct images of spinal cord, which help in diagnosing. Two major maps are accepted by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are widely employed. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.

Dermatomes are skin-like areas which are connected to a particular nerve. In cases of spinal injuries, pain may be felt in a dermatome which is connected to that nerve. The same is true for the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?

Dermatomes are segments of skin supplied by the spinal nerve. These nerves carry motor, sensory, and autonomic messages. They form an element of the peripheral nerve 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 can be treated easily with a local anesthetic.

The dermatomes of the thoracic area are marked by letter-number combinations, which show how the region is connected and the sensory nerve that supplies this area. For instance, the C1 spinal nerve doesn’t have a dematome, however those spinal nerves that are labeled C1-C8 T9, which corresponds to belly button. Dermatomes are layered in horizontally along the trunk, while dermatomes on the extremities tend to be longitudinal.

Dermatome Map

Dermatome maps are the most common element in textbooks that teach anatomy. However, the dermatome map is inconsistency both within and inter-textbook. The name is not consistent and some textbooks include different maps on various pages. This is particularly problematic when the authors of several chapters disagree on the choice of dermatome maps. Most textbooks use maps of Foerster, Keegan, and Garrett however, they do not provide the proper references. Furthermore, four textbooks make use of maps with no citations. This includes one that cites only secondary sources.

The dermatome is the area of skin that receives sensory input from the dorsal root of one spinal nerve. Dermatomes aren’t evenly found, but they tend to dip lower than horizontally. This is a natural variation and some tissues may be covered by multiple dermatomes. In addition to this dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons from the dorsal limbs.
