Dermatomes Nclex Radiculopathy Occupational Therapy Printable Map Of – If you’ve ever wanted to know how the human dermatome map appears, then you’re at the right spot. Before we move on to our map, we’ll take a look at what a dermatome actually is. What are the different types? The most important thing is why is it essential to know about dermatomes in order to comprehend how the body works. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.
What is a Dermatome?
The term “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes play a crucial role in allowing doctors to create maps of the spinal cord, which help in diagnosing. Two major maps are recognized by medical professionals. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still frequently used. The trigeminal and maxillary nerve are the biggest dermatomes.
Dermatomes are skin areas that are attached to a specific nerve bundle. In cases of spinal injury, the pain could be felt in a dermatome that is controlled by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt on specific spinal nerves. If you suffer from nerve pain or neurological problem affecting the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin supplied by one spinal nerve. These nerves provide sensory, motor and autonomic messages. They form a part of the peripheral nervous system, that connects the brain to the rest of the body. Dermatomes can become affected due to a spinal 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 by letter-number combinations, which show the connection between the region as well as the nerve that serves that region. For example the C1 spinal nerve does not have a dematome, however all spinal nerves in the region are labeled C1 – C8 and T9 is a reference to the belly button. Dermatomes are layered horizontally along the trunk, those on the extremities tend to be in a longitudinal.
Dermatome Map
The dermatome map is an integral part of textbooks that teach anatomy. However, the dermatome map is not consistent both within and inter-textbook. The name is not consistent and some textbooks include different maps on different pages. This can be particularly challenging when the authors of different chapters are not unified in their choice of dermatome maps. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett however, they do not provide appropriate references. Furthermore, four textbooks make use of maps with no citations. This includes one that uses only secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip less inferiorly than horizontally. This is a natural variation and some tissues have more than one. In addition to this dorsal spinal rootlets could have intrathecal intersegmental anastomoses to sensory neurons of those limbs that are dorsal.
