Dermatome Map Of Head By Annie Campbell University Of Du Flickr – If you have ever wondered what the human dermatome’s map is, you’ve come to the right spot. Before we go to this map, lets look at the definition of a dermatome. What are the different types? And, most importantly, why is it essential to understand dermatomes in order to know more about our 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 are important in allowing doctors to construct models of the cord that help in diagnosing. Two major maps are accepted by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain often utilized. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin regions that are attached to a specific nerve bundle. In cases of spinal cord injury, the pain could be felt in a dermatome, which is surrounded by the nerve. In the same way, the pain triggered by shingles outbreaks is felt by specific spinal nerves. If you are experiencing pain or neurological condition involving the dermatome region, you need to consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by a single spinal nerve. These nerves provide sensory, motor and autonomic messages. They form an element of the peripheral nerve system which connects the brain with the other parts of the body. A dermatome may become affected due to a spinal lesion. If one of these becomes injured, it could be easily treated with a local anesthetic.
Dermatomes in the thoracic region are identified using letter-number sequences that demonstrate the connection between the region as well as the nerve that is responsible for that area. For instance C1 spinal nerve does not possess a dermatome, however the other spinal nerves are labeled C1 – C8, while T9 corresponds to belly button. Dermatomes are layered vertically on the trunk and dermatomes located in the extremities are usually longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks that cover anatomy. But, the map is not consistent both within and inter-textbook. Its name isn’t consistent and some textbooks include various maps on different pages. This is especially problematic when the authors of several chapters are not unified in their choice of dermatome map. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett but don’t include proper references. Additionally, four textbooks employ maps that do not have citations, such as one that cites only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly placed, however they tend to dip lower than horizontally. This is a natural variation, and certain tissues have more than one. Furthermore, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons of those limbs that are dorsal.
