Dermatome Map Of Head By Annie Campbell University Of Du Flickr – If you’ve ever wanted to know how the human dermatome map appears, then you’re at the right place. Before we look at our map, we’ll take a look at what a dermatome is. What are the different types? The most important thing is why is it necessary to be aware of dermatomes order to understand your body. Continue reading to learn more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers your spinal cord. Dermatomes help doctors to construct models of the cord, which can be useful in diagnosing. Two major maps are recognized by medical professionals. There is the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are often used. The trigeminal and maxillary nerve are the largest dermatomes.
Dermatomes are skin regions that are attached to a particular nerve bundle. When there is a spinal cord injury, the pain could be felt in a dermatome that is connected to that nerve. The same is true for the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you experience a neurologic condition or pain that involves the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin supplied by the spinal nerve. The nerves transmit motor, sensory as well as autonomic information. They form part of the peripheral nerve system, which connects the brain with the all the body. Dermatomes can become affected due to a spinal cord injury. When one of these dermatomes is injured, it can be easily treated using the use of a local anesthetic.
The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate the relationship between the area as well as the nerve that supplies that region. For example the C1 spinal nerve doesn’t have a dematome, however all spinal nerves in the region are identified as C1-C8, while T9 corresponds with the belly button. Dermatomes are laid horizontally on the trunk, those in the extremities are usually long.
Dermatome Map
The dermatome map is an integral part of textbooks that cover anatomy. But, the map is inconsistent both intra and inter-textbook. The names are inconsistent as are some textbooks that have different maps on various pages. This can be particularly challenging when the authors of different chapters disagree on the choice of dermatome maps. Many textbooks use the map of Foerster, Keegan, and Garrett however they don’t provide proper references. In addition, four textbooks utilize maps that do not have citations, such as one that refers to only secondary sources.
Dermatomes are the regions of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip less inferiorly than horizontally. This is a natural variation and certain tissues may be covered by multiple dermatomes. Additionally dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons of those limbs that are dorsal.
