What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers your spinal cord. Dermatomes help doctors to develop maps of the spinal cord, which are useful for diagnosis. Two major maps are accepted by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain commonly used. The trigeminal and maxillary nerve are the biggest dermatomes.
Dermatomes are areas of skin that are linked to a specific nerve bundle. In cases of spinal injury, pain may be experienced in a dermatome that is surrounded by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you suffer from pain or neurological condition involving the dermatome, it is recommended that you consult a physician.

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 a part of the peripheral nerve system, which connects brain and other parts of the body. A dermatome may get affected because of a spinal cord lesion. If one of these becomes injured, it could be treated easily with the use of a local anesthetic.
The dermatomes of the thoracic area are marked with letters-numbers that illustrate the connection between the region as well as the nerve which supplies that area. For instance the C1 spinal nerve does not have a dematome, however the other spinal nerves are labeled C1-C8 and T9 is a reference to belly button. Dermatomes are layered in horizontally on the trunk while dermatomes on the extremities are typically linear.
Dermatome Map
The dermatome map is the most common element in textbooks that teach anatomy. However, the dermatome maps is not uniform both inside and inter-textbook. The names are inconsistent, and some textbooks feature various maps on different pages. This is especially problematic in the event that the authors of various chapters are not unified in their choice of dermatome map. A majority of textbooks employ the Maps of Foerster, Keegan, and Garrett however they don’t provide the proper references. Furthermore, four textbooks make use of maps without citations, including one that refers to only secondary sources.
The dermatome is the area of skin that receives sensory stimulation from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip less inferiorly than horizontally. This is a normal variation and some tissue types are covered with more than one. Additionally dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons of the dorsal limbs.
