Dermatome Map Of Head By Annie Campbell University Of Du Flickr – If you’ve ever wondered what the human dermatome’s map is, you’ve come to the right spot. Before we look at this map, lets talk about the definition of a dermatome. What are the various kinds? And, most importantly, why is it essential to be aware of dermatomes order to better understand your body. Continue reading to learn more. You might 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 spinal cord. Dermatomes are important in allowing doctors to construct diagrams of the spine that aid in the diagnosis. Two major maps are accepted by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still commonly utilized. The trigeminal and maxillary nerve are the biggest dermatomes.
Dermatomes are skin areas that are attached to a specific nerve bundle. When there is a spinal cord injury, the pain could be felt in a dermatome, which is innervated by that nerve. Similarly, the pain caused by shingles outbreaks is felt by specific spinal nerves. If you experience a pain or neurological condition involving the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin supplied by a single spinal nerve. These nerves carry motor, sensory, and autonomic messages. They form a part of the peripheral nerve system, which connects brain and all the body. Dermatomes can be affected by a spinal cord injury. When one of these dermatomes becomes injured, it can be easily treated using the use of a local anesthetic.
The dermatomes of the thoracic region are labeled with letter-number combinations that show the connection between the area in question and the sensory nerve which supplies the area. For example C1 spinal nerve does not have a dermatome, but those spinal nerves that are identified as C1-C8 and T9 refers to the belly button. Dermatomes are layered horizontally on the trunk and dermatomes located on the extremities are typically longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks teaching 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 particularly problematic in the event that the authors of various chapters do not agree on the selection of dermatome maps. Most textbooks use map of Foerster, Keegan, and Garrett however they don’t provide proper references. Additionally, four textbooks employ maps without citations, including one that uses only secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. The dermatomes are not uniformly located, but they tend to dip less inferiorly than horizontally. This is a natural variation and some tissues may be covered by multiple dermatomes. Furthermore, dorsal spinal rootlets may contain intrathecal intersegmental connections with sensory neurons of the dorsal limbs.
