What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes can help doctors to create diagrams of the spine, which aid in the diagnosis. Two major maps are recognized by medical professionals. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and remain frequently utilized. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas that are linked to a particular nerve bundle. In the case of spinal cord injury, pain can be felt in a dermatome that is controlled by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you feel discomfort or neurological issue involving the dermatome area, you must visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is supplied by one spinal nerve. The nerves transmit sensory, motor and autonomic messages. They form a part of the peripheral nervous system, which connects the brain with the other parts of the body. Dermatomes can get affected because of a spinal injury. If one of these becomes injured, it could be easily treated using an local anesthetic.
The dermatomes of the thoracic area are marked by letter-number combinations, which show how the region is connected as well as the nerve which supplies that region. For instance the C1 spinal nerve doesn’t have a dermatome. However, others spinal nerves have been labeled C1-C8 and T9 is a reference to belly button. Dermatomes are layered in vertically on the trunk however, dermatomes on the extremities are typically in a longitudinal.
Dermatome Map
The dermatome map is one of the common features of textbooks that teach anatomy. But, the map is inconsistency both within and inter-textbook. The names are inconsistent, and some textbooks feature different 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 map. Most textbooks use diagrams drawn by Foerster, Keegan, and Garrett but don’t include adequate references. Furthermore, four textbooks make use of maps that do not have citations, such as one that only cites secondary sources.
The dermatome is the area of skin that receives sensory stimulation from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip more inferiorly than horizontally. This is an inherent variation and certain tissue types are covered with more than one. In addition to this dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons in the dorsal parts of the limbs.
