What is a Dermatome?
The term “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes can help doctors to develop maps of the spinal cord, which can be useful in diagnosing. Two major maps are regarded as valid by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still often employed. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.
Dermatomes are areas of skin which are connected to a specific nerve. In the case of spinal cord injury, pain may be felt in a dermatome which is surrounded by the nerve. The same is true for the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you feel discomfort or neurological issue involving the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by only one spinal nerve. These nerves provide motor, sensory and autonomic messages. They form an element of the peripheral nervous system which connects brain and rest of the body. A dermatome may become affected due to a spinal cord injury. When one of these dermatomes becomes injured, it can be treated easily with local anesthetic.
Dermatomes in the thoracic region are labeled by letter-number combinations, which show the connection between the area and the sensory nerve which supplies that area. For instance, the C1 spinal nerve doesn’t have a dermatome. However, all spinal nerves in the region are labeled C1 – C8, while T9 corresponds with the belly button. Dermatomes are layered vertically on the trunk those that are located on the extremities are generally linear.
Dermatome Map
Dermatome maps are one of the common features of textbooks that teach anatomy. However, the dermatome maps is not uniform both inside and inter-textbook. Its name isn’t consistent as are some textbooks that have distinct maps on different pages. This can be particularly challenging when the authors of several chapters differ in their choice of dermatome map. Most textbooks use diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide proper references. In addition, four textbooks utilize maps with no citations. This includes one that uses only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip lower than horizontally. This is a normal variation and certain tissues may be covered by multiple dermatomes. Additionally dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons that originate from Dorsal limbs.
