What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes are important in allowing doctors to create images of spinal cord that are useful for diagnosis. Two major maps are accepted by medical professionals. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are commonly employed. The trigeminal and maxillary nerve are the largest dermatomes.
Dermatomes are skin-like areas which are connected to a particular nerve. In cases of spinal injuries, pain may be experienced in a dermatome that is connected to that nerve. Similarly, the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you experience a discomfort or neurological issue involving the dermatome area, you must visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by a single spinal nerve. These nerves provide sensory, motor, and autonomic signals. They form a part of the peripheral nervous system which connects the brain with the all the body. Dermatomes can get affected because of a spinal cord lesion. If one of these gets injured, it is able to be easily treated using local anesthetic.
The dermatomes of the thoracic area are marked with letter-number combinations that show the connection between the region along with the sensor nerve which supplies that area. For instance C1 spinal nerve doesn’t have a dematome, however others spinal nerves have been labeled as C1-C8 and T9 is a reference with the belly button. Dermatomes are layered horizontally along the trunk, those that are located on the extremities are generally longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks that teach anatomy. The dermatome map is inconsistent both intra and inter-textbook. The names are inconsistent and some textbooks include various maps on different pages. This is particularly problematic when the authors of several chapters disagree on the choice of dermatome maps. Most textbooks use maps of Foerster, Keegan, and Garrett but don’t include adequate references. Additionally, four textbooks employ maps with no citations. This includes one that uses only secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation from the dorsal root of a spinal nerve. The dermatomes are not uniformly placed, however they tend to dip less inferiorly than horizontally. This is a natural variation, and some tissues have more than one. Additionally dorsal spinal rootlets could contain intrathecal intersegmental connections with sensory neurons in the dorsal parts of the limbs.
