Before we go to an image, it’s important to look at what a dermatome is. What are the different kinds? Most importantly, why is it essential to know about dermatomes in order to comprehend the human body. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes can help doctors to create maps of the spinal cord, which aid in the diagnosis. Two maps are widely accepted by medical specialists. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are frequently employed. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin regions that are attached to a particular nerve bundle. In cases of spinal cord injury, pain may be felt in a dermatome which is innervated by that nerve. The same is true for the pain caused by shingles outbreaks is felt by specific spinal nerves. If you experience a neurologic condition or pain that involves the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by the spinal nerve. The nerves transmit motor, sensory, and autonomic messages. They form a part of the peripheral nerve system which connects the brain and other parts of the body. Dermatomes can get affected because of a spinal lesion. If one of these dermatomes gets injured, it is able to be treated easily with an local anesthetic.
Dermatomes in the thoracic region are labeled using letter-number sequences that demonstrate how the region is connected as well as the nerve which supplies this area. For example C1 spinal nerve does not have a dermatome, but the other spinal nerves are labeled as C1-C8, while T9 corresponds with the belly button. Dermatomes are layered horizontally along the trunk, however, dermatomes that are located on the extremities are generally in a longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks that cover anatomy. The dermatome map is not uniform both inside and inter-textbook. Its naming is inconsistent and some textbooks include various maps on different pages. This is particularly problematic 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 do not provide appropriate references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the areas of skin that receives sensory stimulation from the dorsal root of a spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip more inferiorly than horizontally. This is a normal variation and some tissues are covered by more than one dermatome. Furthermore dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons that originate from the dorsal limbs.
