What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the spine. Dermatomes help doctors to develop maps of the spinal cord, which aid in the diagnosis. Two major maps are accepted by medical experts. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are frequently utilized. The trigeminal nerve , as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin areas which are connected to a particular nerve. In cases of spinal cord injury, pain can be felt in a dermatome that is controlled by the nerve. The same is true for the pain caused by shingles outbreaks can be felt in specific spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by the spinal nerve. These nerves provide motor, sensory, as well as autonomic information. They form a part of the peripheral nervous system which connects the brain with the other parts of the body. A dermatome may get affected because of a spinal cord lesion. If one of these dermatomes becomes injured, it can be treated easily with the use of a local anesthetic.
Dermatomes in the thoracic area are marked with letter-number combinations that show the connection between the region in question and the sensory nerve that serves that region. For instance C1 spinal nerve doesn’t possess a dermatome, however others spinal nerves have been identified as C1-C8 and T9 refers with the belly button. Dermatomes are laid vertically on the trunk those in the extremities are usually longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks teaching anatomy. The dermatome map is inconsistency both within and inter-textbook. The name is not consistent as are some textbooks that have various maps on different pages. This can be particularly challenging in the event that the authors of various chapters are not unified in their choice of dermatome maps. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide adequate references. Moreover, four textbooks use maps that do not have citations, such as one that only cites secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly located, but they tend to be more inferior than horizontally. This is a natural variation, and some tissues may be covered by multiple dermatomes. In addition to this, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons in the dorsal parts of the limbs.
