Pin On DERMATOMES – If you’ve ever thought about how the human dermatome map looks, you’ve come to the right place. Before we get to our map, we’ll discuss what is a dermatome. What are the different types? And most importantly, what is the reason to be aware of dermatomes order to better understand the human body. Continue reading to learn more. You might be amazed! 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 help doctors to create images of spinal cord that help in diagnosing. Two major maps are recognized by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are widely utilized. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas that are attached to a specific nerve. In cases of spinal injury, the pain could 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 in particular spinal nerves. If you experience a discomfort or neurological issue involving the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin supplied by a single spinal nerve. These nerves carry sensory, motor, as well as autonomic information. They form part of the peripheral nervous system which connects brain and all the body. Dermatomes can be affected by a spinal cord lesion. If one of these dermatomes becomes injured, it could be easily treated using an local anesthetic.
The dermatomes of the thoracic region are labeled with letters-numbers that illustrate the relationship between the area and the sensory nerve that is responsible for that area. For example the C1 spinal nerve does not have a dermatome, but all spinal nerves in the region are labeled C1 – C8 and T9 is a reference with the belly button. Dermatomes are layered in horizontally on the trunk, those on the extremities are typically linear.
Dermatome Map
The dermatome map is an integral part of textbooks that cover anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. The name is not consistent and some textbooks include distinct maps on different pages. This can be particularly challenging when the authors of different chapters differ in their choice of dermatome maps. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett but don’t include the proper references. In addition, four textbooks utilize maps without citations, including one that cites only secondary sources.
Dermatomes are the parts of skin that receives sensory innervation 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 may be covered by multiple dermatomes. Additionally dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons in the dorsal parts of the limbs.
