What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes play a crucial role in allowing physicians to build images of spinal cord, which are useful for diagnosis. Two maps are widely accepted by medical experts. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still often employed. The trigeminal nerve as well as the maxillary nerve are the biggest dermatomes.

Dermatomes are skin areas that connect to a specific nerve bundle. In the case of spinal cord injuries, pain may be experienced in a dermatome that is surrounded by the nerve. In the same way, the pain triggered by shingles outbreaks can be felt in specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome region, you need to consult a physician.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin that is supplied by a single spinal nerve. These nerves carry motor, sensory, as well as autonomic information. They form an element of the peripheral nerve system, which connects the brain and other parts of the body. A dermatome may suffer from a spinal cord lesion. If one of these becomes injured, it can be easily treated using local anesthetic.

Dermatomes in the thoracic region are labeled with letter-number combinations that show how the region is connected along with the sensor nerve that supplies the area. For example C1 spinal nerve doesn’t possess a dermatome, however those spinal nerves that are labeled as C1-C8 and T9 refers with the belly button. Dermatomes are layered horizontally on the trunk, while dermatomes in the extremities are usually linear.

Dermatome Map

Dermatome maps are the most common element in textbooks that teach anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. The name is not consistent and some textbooks include different maps on various pages. This is particularly problematic in the event that the authors of various chapters disagree on the choice of dermatome map. Most textbooks use Maps of Foerster, Keegan, and Garrett however, they do not provide the proper references. Additionally, four textbooks employ maps without citations, including one that uses only secondary sources.

Dermatomes are the areas of skin that receives sensory innervation from the dorsal branch of one spinal nerve. Dermatomes aren’t uniformly found, but they tend to dip lower than horizontally. This is a natural variation and some tissue types are covered with more than one. Additionally dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons of the dorsal parts of the limbs.
