What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the spine. Dermatomes can help doctors to construct models of the cord that aid in the diagnosis. Two major maps are recognized by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s, and are often employed. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas that are linked to a particular nerve. In the case of spinal cord injuries, pain may be experienced in a dermatome that is surrounded by the nerve. The same is true for the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you feel discomfort or neurological issue involving the dermatome region, you need to 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 messages. They form an element of the peripheral nervous system which connects the brain and all the body. A dermatome may become affected due to a spinal cord lesion. When one of these dermatomes is injured, it can be easily treated using an local anesthetic.
The dermatomes of the thoracic area are marked with letter-number combinations that show the connection between the area in question and the sensory nerve that supplies that region. For example C1 spinal nerve doesn’t have a dermatome. However, all spinal nerves in the region are labeled as C1-C8, while T9 corresponds to belly button. Dermatomes are layered in horizontally on the trunk, and dermatomes located on the extremities tend to be linear.
Dermatome Map
Dermatome maps are the most common element in textbooks that cover anatomy. But, the map is not uniform both inside and inter-textbook. The names are inconsistent and certain textbooks have different maps on various pages. This can be particularly challenging in the event that the authors of various chapters disagree on the choice of dermatome maps. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide proper references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that refers to only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal branch of one spinal nerve. The dermatomes are not uniformly found, but they tend to dip lower than horizontally. This is a normal variation and certain tissues have more than one. Furthermore dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons that originate from Dorsal limbs.
