What is a Dermatome?
The term “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help doctors to create images of spinal cord that help in diagnosing. Two major maps are regarded as valid by medical specialists. These are: the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are widely utilized. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas which are connected to a specific nerve. In cases of spinal injury, the pain could be felt in a dermatome, which is connected to that nerve. Similarly, the pain caused by an outbreak of shingles is felt by specific spinal nerves. If you feel nerve pain or neurological problem affecting the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by one spinal nerve. These nerves carry sensory, motor and autonomic signals. They form a part of the peripheral nerve system which connects the brain and other parts of the body. Dermatomes can be affected by a spinal cord lesion. When one of these dermatomes is injured, it can be treated easily with the use of a local anesthetic.
The dermatomes of the thoracic region are labeled with letters-numbers that illustrate how the region is connected and the sensory nerve that supplies that region. For example C1 spinal nerve does not have a dermatome. However, those spinal nerves that are labeled as C1-C8 and T9 is a reference with the belly button. Dermatomes are layered in horizontally along the trunk, those in the extremities are usually long.
Dermatome Map
Dermatome maps are an integral part of textbooks that cover anatomy. But, the map is not consistent both within and inter-textbook. Its naming is inconsistent, and some textbooks feature various maps on different pages. This is particularly problematic when the authors of different chapters differ in their choice of dermatome map. Many textbooks use the Maps of Foerster, Keegan, and Garrett but don’t include adequate references. In addition, four textbooks utilize maps with no citations, and one of them is one that refers to only secondary sources.
Dermatomes are the regions of the skin that receives sensory information from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip lower than horizontally. This is a natural variation, and certain tissues have more than one. Also dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons in the dorsal parts of the limbs.
