Lumbar Disc Herniation – If you have ever wondered what the human dermatome map looks, you’ve come to the right spot. Before we move on to this map, lets talk about what a dermatome actually is. What are the various types? And, most importantly, what is the reason to understand dermatomes in order to comprehend our body. 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 play a crucial role in allowing doctors to develop images of spinal cord that help in diagnosing. Two major maps are regarded as valid by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still often utilized. The trigeminal and maxillary nerve are the largest dermatomes.
Dermatomes are areas of skin that are linked to a particular nerve bundle. When there is a spinal cord injuries, pain may be felt in a dermatome that is surrounded by the nerve. Similarly, the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you feel nerve pain or neurological problem affecting the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is provided by only one spinal nerve. These nerves provide sensory, motor and autonomic signals. They form an element of the peripheral nervous system which connects the brain with the all the body. Dermatomes can become affected due to a spinal lesion. If one of these becomes injured, it can be treated easily with local anesthetic.
The dermatomes of the thoracic region are labeled with letters-numbers that illustrate the relationship between the area in question and the sensory nerve that serves that region. For instance, the C1 spinal nerve does not have a dermatome. However, those spinal nerves that are labeled C1-C8 T9, which corresponds to belly button. Dermatomes are layered in vertically on the trunk however, dermatomes in the extremities are usually long.
Dermatome Map
The dermatome map is the most common element in textbooks that cover anatomy. But, the map is inconsistent both intra and inter-textbook. Its name isn’t consistent, and some textbooks feature various maps on different pages. This is particularly problematic when the authors of multiple chapters differ in their choice of dermatome maps. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett but do not include appropriate 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 stimulation from the dorsal roots of one spinal nerve. The dermatomes are not uniformly situated, but they tend to be more inferior than horizontally. This is an inherent variation and some tissues have more than one. Also dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons in the dorsal limbs.
