Pin On Occupational Therapy – If you’ve ever thought about what the human dermatome’s map appears, then you’re at the right place. Before we get to an image, it’s important to talk about the definition of a dermatome. What are the different types? And most importantly, why is it important to be aware of dermatomes order to understand your body. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.
What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes are important in allowing doctors to create diagrams of the spine, which are useful for diagnosis. Two major maps are accepted by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are often used. 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 bundle. In cases of spinal injury, pain may be felt in a dermatome which is controlled by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you suffer from discomfort or neurological issue involving the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin supplied by the spinal nerve. The nerves transmit sensory, motor, and autonomic signals. They form part of the peripheral nervous system, which connects brain and all the body. Dermatomes can suffer from a spinal lesion. If one of these becomes injured, it could be treated easily with an local anesthetic.
The dermatomes of the thoracic region are labeled with letters-numbers that illustrate the connection between the region in question and the sensory nerve that is responsible for that region. For instance, the C1 spinal nerve doesn’t have a dematome, however the other spinal nerves are labeled as C1-C8 and T9 is a reference to the belly button. Dermatomes are layered in horizontally on the trunk, however, dermatomes on the extremities are typically linear.
Dermatome Map
The dermatome map is an integral part of textbooks that cover anatomy. But, the map is not consistent both within and inter-textbook. The name is not consistent and certain textbooks have different maps on various pages. This is particularly problematic when the authors of different chapters disagree on the choice of dermatome map. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett but don’t include proper references. Moreover, four textbooks use maps with no citations. This includes one that cites only secondary sources.
Dermatomes are the areas of skin that receives sensory input from the dorsal roots of one spinal nerve. The dermatomes are not uniformly placed, however they tend to dip more inferiorly than horizontally. This is a natural variation and some tissues may be covered by multiple dermatomes. Additionally, dorsal spinal rootlets may have intrathecal intersegmental anastomoses with sensory neurons of the dorsal limbs.
