Before we move on to an image, it’s important to discuss what a dermatome actually is. What are the different kinds? And most importantly, why is it important to know about dermatomes in order to comprehend your body. Read on to find out more. You might be amazed! Here are some examples of dermatomes.
What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes play a crucial role in allowing doctors to create maps of the spinal cord that aid in the diagnosis. Two major maps are recognized by medical specialists. The Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain frequently employed. The trigeminal and maxillary nerves are the two largest dermatomes.
Dermatomes are skin areas which are connected to a particular nerve. In cases of spinal cord injuries, pain may be experienced in a dermatome that is connected to that nerve. The same is true for the pain caused by shingles outbreaks can be felt in specific spinal nerves. If you experience a neurologic condition or pain that involves the dermatome, you should consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by one spinal nerve. These nerves relay sensory, motor, and autonomic information. They form part of the peripheral nervous system which connects brain and all the body. A dermatome may get affected because of a spinal cord lesion. If one of these becomes injured, it could be easily treated with local anesthetic.
Dermatomes in the thoracic region have been labeled by letter-number combinations, which show the connection between the region as well as the nerve which supplies that area. For instance C1 spinal nerve doesn’t have a dermatome, but others spinal nerves have been labeled C1 – C8, while T9 corresponds to belly button. Dermatomes are layered horizontally along the trunk, however, dermatomes on the extremities are typically in a longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks that cover anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. Its naming is inconsistent and some textbooks include distinct maps on different pages. This can be particularly challenging when the authors of different chapters disagree on the choice of dermatome map. A majority of textbooks employ the map of Foerster, Keegan, and Garrett but don’t include adequate references. Moreover, four textbooks use maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the parts of skin that receives sensory stimulation from the dorsal root of one spinal nerve. The dermatomes are not uniformly placed, however they tend to dip lower than horizontally. This is a natural variation, and certain tissues may be covered by multiple dermatomes. Additionally dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons that originate from Dorsal limbs.
