What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes help doctors to develop maps of the spinal cord, which aid in the diagnosis. Two major maps are recognized by medical specialists. There is the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still frequently used. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin regions which are connected to a particular nerve bundle. When there is a spinal cord injury, pain can be experienced in a dermatome that is innervated by that nerve. The same is true for the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you feel neurologic condition or pain that involves the dermatome, you should consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part 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 with the all the body. A dermatome may become affected due to a spinal injury. If one of these dermatomes is injured, it can be easily treated with an local anesthetic.
Dermatomes in the thoracic region have been labeled by letter-number combinations, which show the relationship between the area along with the sensor nerve which supplies this area. For example, the C1 spinal nerve does not possess a dermatome, however all spinal nerves in the region are identified as C1-C8 and T9 refers to belly button. Dermatomes are laid horizontally on the trunk, and dermatomes located in the extremities are usually longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks that teach anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. Its naming is inconsistent as are some textbooks that have different maps on different pages. This is especially problematic in the event that the authors of various chapters disagree on the choice of dermatome maps. Most textbooks use map of Foerster, Keegan, and Garrett but don’t include adequate references. Additionally, four textbooks employ maps without citations, including one that cites only secondary sources.
Dermatomes are the areas of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly located, but they tend to dip more inferiorly than horizontally. This is an inherent variation and certain tissues are covered by more than one dermatome. Furthermore dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons in Dorsal limbs.
