Before we get to an image, it’s important to take a look at what a dermatome is. What are the different types? And, most importantly, what is the reason to know about dermatomes in order to comprehend our body. Continue reading to learn more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the spine. Dermatomes play a crucial role in allowing doctors to develop images of spinal cord, which aid in the diagnosis. Two maps are widely accepted by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain often employed. The trigeminal nerve , as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin regions that are linked to a particular nerve. In the case of spinal cord injuries, pain may be felt in a dermatome, which is connected to that nerve. Similarly, the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you experience a neurologic condition or pain that involves the dermatome area, you must visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin supplied by the spinal nerve. These nerves relay motor, sensory, as well as autonomic information. They form part of the peripheral nerve 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 dermatomes becomes injured, it could be easily treated using a local anesthetic.
Dermatomes in the thoracic region are identified using letter-number sequences that demonstrate the relationship between the area as well as the nerve that supplies that area. For example C1 spinal nerve doesn’t have a dermatome, but the other spinal nerves are labeled C1-C8 and T9 refers to the belly button. Dermatomes are laid vertically on the trunk however, dermatomes that are located on the extremities are generally longitudinal.
Dermatome Map
Dermatome maps are an integral part of textbooks that teach anatomy. The dermatome map is not consistent both within and inter-textbook. Its name isn’t consistent and certain textbooks have different maps on different pages. This is especially problematic when the authors of multiple chapters are not unified in their choice of dermatome maps. Most textbooks use Maps of Foerster, Keegan, and Garrett but do not include proper references. Furthermore, four textbooks make use of maps that do not have citations, such as one that cites only secondary sources.
The dermatome is the area of skin that receives sensory innervation 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 natural variation and certain tissues have more than one. Furthermore, dorsal spinal rootlets may have intrathecal intersegmental anastomoses with sensory neurons of the dorsal parts of the limbs.
