What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers your spinal cord. Dermatomes are important in allowing doctors to create images of spinal cord, which can be useful in diagnosing. Two maps are widely accepted by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are often used. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that connect to a particular nerve. In cases of spinal injury, pain can be experienced in a dermatome that is controlled by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt on specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin supplied by a single spinal nerve. These nerves relay motor, sensory, and autonomic messages. They form a part of the peripheral nerve system, which connects brain and all the body. Dermatomes can be affected by a spinal injury. If one of these dermatomes becomes injured, it can be treated easily with an local anesthetic.
Dermatomes in the thoracic region have been labeled with letter-number combinations that show the connection between the region as well as the nerve that serves the area. For instance C1’s spinal nerve doesn’t have a dermatome. However, those spinal nerves that are labeled C1-C8 T9, which corresponds to the belly button. Dermatomes are layered in horizontally on the trunk, and dermatomes located that are located on the extremities are generally long.
Dermatome Map
The dermatome map is one of the common features of textbooks that cover anatomy. However, the dermatome map is not uniform both inside and inter-textbook. Its naming is inconsistent and certain textbooks have different maps on various pages. This is particularly problematic when the authors of several chapters differ in their choice of dermatome maps. A majority of textbooks employ the map of Foerster, Keegan, and Garrett however, they do not provide the proper references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that uses only secondary sources.
Dermatomes are the parts of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip less inferiorly than horizontally. This is an inherent variation and some tissues may be covered by multiple dermatomes. Furthermore dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal limbs.
