Dermatomes And Myotomes Sensation Anatomy Geeky Medics – If you’ve ever thought about what the human dermatome map is, you’ve come to the right spot. Before we move on to the map, let’s look at what a dermatome is. What are the various kinds? And most importantly, why is it essential to learn about dermatomes in order to comprehend how the body works. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers the spine. Dermatomes are important in allowing physicians to build maps of the spinal cord, which are useful for diagnosis. 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 widely used. The trigeminal nerve , as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are areas of skin that are linked to a particular nerve. In the case of spinal cord injury, pain can be felt in a dermatome that is innervated by that nerve. In the same way, the pain triggered by an outbreak of shingles can be felt on specific spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by one spinal nerve. These nerves relay motor, sensory, and autonomic information. They form a 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 becomes injured, it could be easily treated with the use of a local anesthetic.
Dermatomes in the thoracic region are identified by letter-number combinations, which show the connection between the region as well as the nerve that supplies the area. For instance, the C1 spinal nerve doesn’t have a dermatome, but others spinal nerves have been identified as C1-C8 T9, which corresponds to the belly button. Dermatomes are layered horizontally on the trunk, however, dermatomes on the extremities tend to be longitudinal.
Dermatome Map
The dermatome map is the most common element in textbooks that cover anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. The name is not consistent and some textbooks include distinct maps on different pages. This is especially problematic when the authors of different chapters differ in their choice of dermatome maps. Most textbooks use map of Foerster, Keegan, and Garrett however, they do not provide the proper references. Furthermore, four textbooks make use of maps without citations, including one that cites only secondary sources.
The dermatome is the area of skin that receives sensory input from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to be more inferior than horizontally. This is an inherent variation and certain tissues may be covered by multiple dermatomes. Furthermore dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons from Dorsal limbs.
