Dermatome Myotome Occupational Therapy Spinal Nerve Physical Therapy – If you’ve ever wanted to know how the human dermatome map appears, then you’re at the right place. Before we get to our map, we’ll talk about what is a dermatome. What are the various types? And, most importantly, why is it important to know about dermatomes in order to know more about 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 your spinal cord. Dermatomes can help doctors to construct diagrams of the spine that can be useful in diagnosing. Two maps are widely accepted by medical professionals. There is the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and remain widely employed. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin regions that connect to a specific nerve bundle. In cases of spinal cord injury, the pain could be felt in a dermatome that is controlled by the nerve. The same is true for the pain caused by shingles outbreaks is felt by specific spinal nerves. If you feel discomfort or neurological issue involving the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by only one spinal nerve. These nerves carry sensory, motor, as well as autonomic information. They form part of the peripheral nerve system which connects brain and other parts of the body. Dermatomes can get affected because of a spinal injury. When one of these dermatomes is injured, it can be easily treated using a local anesthetic.
The dermatomes of the thoracic area are marked with letters-numbers that illustrate the relationship between the area as well as the nerve that serves that area. For instance C1 spinal nerve does not have a dermatome. However, others spinal nerves have been labeled as C1-C8 and T9 refers with the belly button. Dermatomes are layered horizontally on the trunk, however, dermatomes on the extremities tend to be linear.
Dermatome Map
The dermatome map is the most common element in textbooks that cover anatomy. However, the dermatome map is inconsistency both within and inter-textbook. The name is not consistent and some textbooks include distinct maps on different pages. This is particularly problematic when the authors of several chapters are not unified in their choice of dermatome map. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett but don’t include adequate references. In addition, four textbooks utilize maps with no citations. This includes one that only cites secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. Dermatomes aren’t 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. In addition to this dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons of those limbs that are dorsal.
