What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the spinal cord. Dermatomes help doctors to develop models of the cord, which can be useful in diagnosing. Two maps are widely accepted by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still frequently utilized. The trigeminal and maxillary nerve are the biggest dermatomes.
Dermatomes are areas of skin that are attached to a particular nerve. In cases of spinal injury, pain can be felt in a dermatome that is connected to that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in specific spinal nerves. If you suffer from discomfort or neurological issue involving the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by the spinal nerve. These nerves carry motor, sensory and autonomic signals. They form part of the peripheral nerve system, which connects the brain and other parts of the body. A dermatome may become affected due to a spinal cord lesion. If one of these dermatomes is injured, it can be easily treated with the use of a local anesthetic.
Dermatomes in the thoracic region are labeled with letters-numbers that illustrate the relationship between the area and the sensory nerve which supplies the area. For example C1’s spinal nerve doesn’t have a dermatome. However, those spinal nerves that are labeled C1 – C8 and T9 is a reference to the belly button. Dermatomes are layered in horizontally along the trunk, while dermatomes that are located on the extremities are generally longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks that teach anatomy. However, the dermatome map is not uniform both inside and inter-textbook. The name is not consistent and some textbooks include distinct maps on different pages. This can be particularly challenging when the authors of several chapters disagree on the choice of dermatome maps. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett however, they do not provide the proper references. Additionally, four textbooks employ maps with no citations. This includes one that refers to only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly located, but they tend to dip more inferiorly than horizontally. This is a normal variation and certain tissue types are covered with more than one. In addition to this dorsal spinal nerve roots may contain intrathecal intersegmental connections with sensory neurons from the dorsal parts of the limbs.
