What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the spine. Dermatomes help doctors to construct maps of the spinal cord that can be useful in diagnosing. Two major maps are accepted by medical specialists. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s, and are frequently used. The trigeminal nerve and the maxillary nerve are the largest dermatomes.

Dermatomes are skin-like areas which are connected to a particular nerve. In cases of spinal injury, pain may be felt in a dermatome that is connected to that nerve. In the same way, the pain triggered by an outbreak of shingles is felt by specific spinal nerves. If you experience a pain or neurological condition involving the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?

A dermatome is a segment of skin supplied by one spinal nerve. These nerves carry sensory, motor and autonomic messages. They form an element of the peripheral nerve system that connects the brain to the rest of the body. A dermatome may become affected due to a spinal cord lesion. If one of these gets injured, it is able to be treated easily with an local anesthetic.

The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate the connection between the region and the sensory nerve that serves this area. For instance C1’s spinal nerve does not possess a dermatome, however the other spinal nerves are identified as C1-C8, while T9 corresponds to belly button. Dermatomes are laid horizontally on the trunk those on the extremities are typically linear.

Dermatome Map

The dermatome map is one of the common features of textbooks that teach anatomy. The dermatome map is inconsistent both intra and inter-textbook. Its name isn’t consistent and certain textbooks have distinct maps on different pages. This is particularly problematic in the event that the authors of various chapters differ in their choice of dermatome map. The majority of textbooks utilize the map of Foerster, Keegan, and Garrett however they don’t provide appropriate references. Furthermore, four textbooks make use of maps with no citations. This includes one that refers to only secondary sources.

Dermatomes are the areas of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly placed, however they tend to dip less inferiorly than horizontally. This is a normal variation and certain tissues may be covered by multiple dermatomes. Additionally dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons of the dorsal limbs.
