Printable Dermatome Map Printable Maps – If you have ever wondered how the human dermatome chart will look, you’re in the right place. Before we get to this map, lets look at what a dermatome actually is. What are the different types? The most important thing is what is the reason to learn about dermatomes in order to better understand how the body works. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.
What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes are important in allowing doctors to construct diagrams of the spine, which are useful for diagnosis. Two major maps are regarded as valid by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are commonly employed. The trigeminal nerve , as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are skin-like areas that connect to a specific nerve. In the case of spinal cord injury, pain can be felt in a dermatome which is innervated by that nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in specific spinal nerves. If you are experiencing nerve pain or neurological problem affecting the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is provided by a single spinal nerve. These nerves carry motor, sensory, and autonomic signals. They form part of the peripheral nerve system, which connects brain and all the body. Dermatomes can be affected by a spinal lesion. When one of these dermatomes becomes injured, it could be easily treated with the use of a local anesthetic.
Dermatomes in the thoracic region have been labeled with letters-numbers that illustrate how the region is connected and the sensory nerve that supplies that area. For instance C1’s spinal nerve does not have a dermatome. However, all spinal nerves in the region are labeled as C1-C8, while T9 corresponds with the belly button. Dermatomes are laid vertically on the trunk while dermatomes on the extremities tend to be in a longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks that cover anatomy. But, the map is not uniform both inside and inter-textbook. Its name isn’t consistent and some textbooks include distinct maps on different pages. This is especially problematic when the authors of several chapters are not unified in their choice of dermatome map. Many textbooks use the Maps of Foerster, Keegan, and Garrett but do not include adequate references. In addition, four textbooks utilize maps with no citations. This includes one that refers to only secondary sources.
Dermatomes are the areas of skin that receives sensory innervation from the dorsal branch 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 have more than one. Also, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons that originate from those limbs that are dorsal.
