What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes are important in allowing physicians to build models of the cord that are useful for diagnosis. Two major maps are accepted by medical professionals. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are frequently used. The trigeminal nerve as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are skin areas which are connected to a particular nerve. In the case of spinal cord injury, pain may be felt in a dermatome, which is innervated by that nerve. In the same way, the pain triggered by shingles outbreaks can be felt in specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is supplied by a single spinal nerve. These nerves carry sensory, motor, and autonomic information. They form a part of the peripheral nervous system, that connects the brain to the other parts of the body. A dermatome may get affected because of a spinal lesion. If one of these dermatomes becomes injured, it could be easily treated using local anesthetic.
Dermatomes in the thoracic area are marked using letter-number sequences that demonstrate the relationship between the area in question and the sensory nerve which supplies the area. For instance, the C1 spinal nerve does not have a dermatome. However, the other spinal nerves are identified as C1-C8 and T9 refers to the belly button. Dermatomes are layered horizontally along the trunk, those that are located on the extremities are generally longitudinal.
Dermatome Map
Dermatome maps are an integral part of textbooks that cover anatomy. The dermatome map is not uniform both inside and inter-textbook. Its name isn’t consistent, and some textbooks feature distinct maps on different pages. This is particularly problematic when the authors of several chapters are not unified in their choice of dermatome map. The majority of textbooks utilize the maps of Foerster, Keegan, and Garrett however, they do not provide proper references. Additionally, four textbooks employ maps with no citations. This includes one that refers to only secondary sources.
The dermatome is the area of skin that receives sensory input from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip lower than horizontally. This is a natural variation and some tissues are covered by more than one dermatome. Additionally dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons of the dorsal limbs.
