What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes help physicians to build diagrams of the spine, which aid in the diagnosis. Two maps are widely accepted by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are frequently utilized. The trigeminal and maxillary nerve are the largest dermatomes.

Dermatomes are skin-like areas that connect to a particular nerve. In cases of spinal injury, pain may be felt in a dermatome, which is innervated by that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt on specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is provided by only one spinal nerve. These nerves carry motor, sensory as well as autonomic information. They form part of the peripheral nerve system which connects brain and rest of the body. Dermatomes can become affected due to a spinal cord injury. If one of these is injured, it can be easily treated using a local anesthetic.

Dermatomes in the thoracic region have been labeled by letter-number combinations, which show the connection between the region in question and the sensory nerve that is responsible for that region. For instance the C1 spinal nerve doesn’t possess a dermatome, however those spinal nerves that are labeled C1-C8 T9, which corresponds with the belly button. Dermatomes are layered in horizontally on the trunk and dermatomes located on the extremities tend to be long.

The dermatome map is one of the common features of textbooks that teach anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. Its name isn’t consistent, and some textbooks feature different maps on different pages. This can be particularly challenging in the event that the authors of various chapters do not agree on the selection of dermatome map. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide adequate references. Furthermore, four textbooks make use of maps that do not have citations, such as one that refers to only secondary sources.

Dermatomes are the parts of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly located, but they tend to dip more inferiorly than horizontally. This is an inherent variation and some tissues are covered by more than one dermatome. Additionally dorsal spinal rootlets could contain intrathecal intersegmental connections with sensory neurons that originate from Dorsal limbs.
