Trigeminal Nerve V – If you’ve ever wanted to know what the human dermatome map looks, you’ve come to the right spot. Before we get to an image, it’s important to look at what is a dermatome. What are the different types? The most important thing is what is the reason to learn about dermatomes in order to better understand the human body. Read on to find out 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 covers the spine. Dermatomes are important in allowing doctors to develop images of spinal cord that are useful for diagnosis. Two maps are widely accepted by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still commonly used. The trigeminal and maxillary nerve are the biggest dermatomes.
Dermatomes are skin regions that connect to a particular nerve bundle. In the case of spinal cord injury, the pain could be felt in a dermatome that is surrounded by the nerve. Similarly, the pain caused by an outbreak of shingles is felt by specific spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is supplied by a single spinal nerve. The nerves transmit motor, sensory, and autonomic signals. They form part of the peripheral nervous system, which connects the brain with the rest of the body. A dermatome may be affected by a spinal injury. If one of these is injured, it can be treated easily with local anesthetic.
Dermatomes in the thoracic region are labeled with letters-numbers that illustrate the connection between the region along with the sensor nerve which supplies that area. For example C1’s spinal nerve does not have a dermatome. However, those spinal nerves that are labeled C1 – C8 and T9 refers to the belly button. Dermatomes are laid horizontally along the trunk, however, dermatomes on the extremities tend to be linear.
Dermatome Map
The dermatome map is one of the common features of textbooks that teach anatomy. The dermatome map is inconsistency both within and inter-textbook. Its name isn’t consistent as are some textbooks that have various maps on different pages. This is particularly problematic when the authors of different chapters disagree on the choice of dermatome map. A majority of textbooks employ the Maps of Foerster, Keegan, and Garrett but do not include proper references. In addition, four textbooks utilize maps with no citations. This includes one that uses only secondary sources.
Dermatomes are the areas of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip more inferiorly than horizontally. This is a natural variation, and certain tissues may be covered by multiple dermatomes. Additionally dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons of those limbs that are dorsal.
