What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes play a crucial role in allowing doctors to develop models of the cord that aid in the diagnosis. Two major maps are accepted by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are frequently employed. The trigeminal and maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that are linked to a particular nerve. When there is a spinal cord injury, pain can be experienced in a dermatome that is connected to that nerve. In the same way, the pain triggered by shingles outbreaks is felt by specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome region, you need to consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by a single spinal nerve. These nerves carry sensory, motor, and autonomic signals. They form part of the peripheral nerve system that connects the brain to the all the body. A dermatome may become affected due to a spinal injury. When one of these dermatomes gets injured, it is able to be easily treated using an local anesthetic.
Dermatomes in the thoracic area are marked with letters-numbers that illustrate the connection between the region and the sensory nerve that is responsible for the area. For example, the C1 spinal nerve doesn’t have a dematome, however all spinal nerves in the region are labeled C1 – C8 T9, which corresponds to belly button. Dermatomes are layered horizontally along the trunk, while dermatomes on the extremities tend to be linear.
Dermatome Map
Dermatome maps are a common feature of textbooks teaching anatomy. However, the dermatome map is not uniform both inside and inter-textbook. The name is not consistent as are some textbooks that have different maps on various pages. This is particularly problematic when the authors of multiple chapters disagree on the choice of dermatome map. A majority of textbooks employ the map of Foerster, Keegan, and Garrett however they don’t provide appropriate references. Additionally, four textbooks employ maps with no citations, and one of them is 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 natural variation and certain tissues may be covered by multiple dermatomes. Also, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons that originate from those limbs that are dorsal.
