Dermatomes What Are They Dr Michael A Castillo MD – If you’ve ever wanted to know how the human dermatome chart looks, you’ve come to the right spot. Before we go to the map, let’s discuss what is a dermatome. What are the various types? Most importantly, why is it necessary to be aware of dermatomes order to know more about your body. Read on to find out more. You might be surprised! 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 models of the cord that are useful for diagnosis. Two major maps are regarded as valid by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still widely employed. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.
Dermatomes are skin-like areas that connect to a specific nerve. In cases of spinal cord injury, pain can be felt in a dermatome, which is surrounded by the nerve. Similarly, the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you experience a pain or neurological condition involving the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by one spinal nerve. These nerves carry motor, sensory, and autonomic information. They form a part of the peripheral nerve system, which connects brain and rest of the body. Dermatomes can become affected due to a spinal lesion. If one of these dermatomes is injured, it can be easily treated with an local anesthetic.
The dermatomes of the thoracic region are labeled with letter-number combinations that show the connection between the area in question and the sensory nerve which supplies that area. For instance C1 spinal nerve doesn’t possess a dermatome, however the other spinal nerves are labeled as C1-C8 T9, which corresponds to the belly button. Dermatomes are layered horizontally along the trunk, those in the extremities are usually longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks teaching anatomy. The dermatome map is inconsistency both within and inter-textbook. The name is not consistent as are some textbooks that have different maps on different pages. This can be particularly challenging when the authors of multiple chapters differ in their choice of dermatome maps. Most textbooks use map of Foerster, Keegan, and Garrett but don’t include proper references. Furthermore, four textbooks make use of maps without citations, including one that refers to only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly found, but they tend to dip lower than horizontally. This is a normal variation and certain tissues may be covered by multiple dermatomes. In addition to this dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons that originate from those limbs that are dorsal.
