Dermatomes Of Upper Limb Patient Education Physical Therapy – If you’ve ever wanted to know what the human dermatome map will look, you’re in the right spot. Before we move on to our map, we’ll take a look at the definition of a dermatome. What are the various types? And, most importantly, why is it essential to learn about dermatomes in order to better understand our body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers your spinal cord. Dermatomes can help doctors to develop models of the 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 developed in the 1930s and are still frequently employed. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin regions which are connected to a specific nerve bundle. In cases of spinal injury, pain can be felt in a dermatome which is innervated by that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in particular spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome, you should consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by the spinal nerve. These nerves carry motor, sensory, and autonomic information. They form an element of the peripheral nervous system which connects brain and rest of the body. A dermatome may suffer from a spinal cord injury. If one of these dermatomes becomes injured, it can be treated easily with an local anesthetic.
Dermatomes in the thoracic area are marked with letters-numbers that illustrate the connection between the region as well as the nerve which supplies the area. For example C1 spinal nerve does not have a dematome, however those spinal nerves that are labeled C1-C8 and T9 is a reference with the belly button. Dermatomes are layered in horizontally on the trunk those that are located on the extremities are generally long.
Dermatome Map
The dermatome map is one of the common features of textbooks that teach anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. Its name isn’t consistent, and some textbooks feature different maps on various pages. This is particularly problematic when the authors of different chapters are not unified in their choice of dermatome maps. A majority of textbooks employ the map of Foerster, Keegan, and Garrett but don’t include appropriate references. Additionally, four textbooks employ maps with no citations, and one of them is 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. The dermatomes are not uniformly placed, however they tend to dip lower than horizontally. This is an inherent variation and certain tissues have more than one. Also dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons from the dorsal parts of the limbs.
