Before we look at this map, lets look at what is a dermatome. What are the different types? The most important thing is why is it important to be aware of dermatomes order to understand how the body works. Continue reading to learn more. You might be amazed! Here are some examples of dermatomes.
Dermatomes Definition Chart And Diagram
What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that covers the spine. Dermatomes help doctors to develop images of spinal cord, which help in diagnosing. Two maps are widely accepted by medical experts. The Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still often employed. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.
Dermatomes are skin-like areas that connect to a particular nerve bundle. In cases of spinal cord injury, the pain could be felt in a dermatome that is surrounded by the nerve. The same is true for the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you experience a neurologic condition or pain that involves the dermatome region, you need to consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by only one spinal nerve. These nerves carry motor, sensory, as well as autonomic information. They form part of the peripheral nervous system, which connects the brain and rest of the body. A dermatome may become affected due to a spinal injury. If one of these gets injured, it is able to be easily treated using a local anesthetic.
The dermatomes of the thoracic region are identified with letter-number combinations that show the connection between the area along with the sensor nerve which supplies that region. For instance the C1 spinal nerve does not possess a dermatome, however those spinal nerves that are identified as C1-C8 T9, which corresponds to the belly button. Dermatomes are layered horizontally on the trunk however, dermatomes that are located on the extremities are generally in a longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks that teach anatomy. However, the dermatome map is not consistent both within and inter-textbook. Its naming is inconsistent and some textbooks include distinct maps on different pages. This can be particularly challenging when the authors of different chapters are not unified in their choice of dermatome map. Many textbooks use the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide appropriate references. In addition, four textbooks utilize maps with no citations, and one of them is one that refers to only secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. The dermatomes are not uniformly placed, however they tend to dip less inferiorly than horizontally. This is an inherent variation and some tissue types are covered with more than one. Furthermore dorsal spinal rootlets could have intrathecal intersegmental anastomoses to sensory neurons in Dorsal limbs.
