Shingles UF Health University Of Florida Health – If you have ever wondered what the human dermatome map is, you’ve come to the right spot. Before we get to an image, it’s important to discuss what is a dermatome. What are the various kinds? The most important thing is what is the reason to understand dermatomes in order to understand the human body. Continue reading to learn more. You might be amazed! Here are some examples of dermatomes.
What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers the spine. Dermatomes help physicians to build maps of the spinal cord, which are useful for diagnosis. Two major maps are recognized by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain widely utilized. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin-like areas which are connected to a specific nerve bundle. When there is a spinal cord injury, pain may be felt in a dermatome that is surrounded by the nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in specific spinal nerves. If you suffer from nerve pain or neurological problem affecting the dermatome, it is recommended that you see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by only one spinal nerve. These nerves carry motor, sensory, and autonomic messages. They form a part of the peripheral nervous system, which connects the brain and rest of the body. Dermatomes can become affected due to a spinal cord lesion. If one of these dermatomes is injured, it can be easily treated with local anesthetic.
The dermatomes of the thoracic region are identified with letter-number combinations that show the connection between the area in question and the sensory nerve which supplies that area. For example C1’s spinal nerve doesn’t have a dematome, however the other spinal nerves are labeled as C1-C8 and T9 refers to belly button. Dermatomes are layered horizontally on the trunk, those that are located on the extremities are generally long.
Dermatome Map
The dermatome map is the most common element in textbooks teaching anatomy. But, the map is inconsistency both within and inter-textbook. The name is not consistent as are some textbooks that have distinct maps on different pages. This is especially problematic in the event that the authors of various chapters are not unified in their choice of dermatome maps. A majority of textbooks employ the map of Foerster, Keegan, and Garrett however they don’t provide adequate references. In addition, four textbooks utilize maps with no citations, and one of them is one that only cites secondary sources.
Dermatomes are the parts of skin that receives sensory stimulation from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly located, but they tend to be more inferior than horizontally. This is a normal variation and certain tissues have more than one. Also dorsal spinal rootlets could have intrathecal intersegmental anastomoses to sensory neurons that originate from the dorsal parts of the limbs.
