Before we look at our map, we’ll talk about what a dermatome is. What are the different types? And most importantly, why is it necessary to learn about dermatomes in order to comprehend how the body works. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.
What is a Dermatome?
The term “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes help physicians to build maps of the spinal cord, which aid in the diagnosis. Two major maps are regarded as valid by medical experts. They are the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and remain widely employed. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin areas that are attached to a specific nerve bundle. In the case of spinal cord injury, pain may be felt in a dermatome, which is surrounded by the nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in particular spinal nerves. If you feel neurologic condition or pain that involves the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by a single spinal nerve. The nerves transmit motor, sensory, and autonomic signals. They form a part of the peripheral nervous system that connects the brain to the all the body. A dermatome may suffer from a spinal cord lesion. If one of these dermatomes gets injured, it is able to be easily treated with an local anesthetic.
The dermatomes of the thoracic region are labeled with letter-number combinations that show how the region is connected in question and the sensory nerve that serves this area. For instance the C1 spinal nerve doesn’t have a dematome, however those spinal nerves that are labeled C1-C8 and T9 is a reference to belly button. Dermatomes are layered horizontally on the trunk those in the extremities are usually in a longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks that teach anatomy. The dermatome map is inconsistency both within and inter-textbook. Its naming is inconsistent and some textbooks include different maps on various pages. This is particularly problematic when the authors of multiple chapters are not unified in their choice of dermatome maps. The majority of textbooks utilize the maps of Foerster, Keegan, and Garrett but do not include appropriate references. In addition, four textbooks utilize maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the areas of the skin that receives sensory information from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip lower than horizontally. This is a natural variation, and certain tissues are covered by more than one dermatome. In addition to this dorsal spinal rootlets could have intrathecal intersegmental anastomoses with sensory neurons from the dorsal limbs.
