What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help doctors to develop models of the cord, which can be useful in diagnosing. Two maps are widely accepted by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain widely utilized. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas which are connected to a specific nerve bundle. In cases of spinal cord injuries, pain may be experienced in a dermatome that is controlled by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt in particular spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome area, you must visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin supplied by one spinal nerve. These nerves provide motor, sensory, and autonomic information. They form a part of the peripheral nervous system, that connects the brain to the rest of the body. Dermatomes can be affected by a spinal injury. When one of these dermatomes becomes injured, it could be treated easily with the use of a local anesthetic.
Dermatomes in the thoracic region have been labeled with letter-number combinations that show the relationship between the area as well as the nerve that is responsible for this area. For example C1 spinal nerve does not have a dermatome, but all spinal nerves in the region are labeled C1-C8 T9, which corresponds with the belly button. Dermatomes are layered in vertically on the trunk while dermatomes on the extremities tend to be longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks teaching anatomy. However, the dermatome map is not consistent both within and inter-textbook. The names are inconsistent and some textbooks include various maps on different pages. This is particularly problematic when the authors of several chapters do not agree on the selection of dermatome maps. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett however they don’t provide proper references. Additionally, four textbooks employ maps that do not have citations, such as one that cites only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal root of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip more inferiorly than horizontally. This is a natural variation and some tissues have more than one. Additionally dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons that originate from the dorsal limbs.
