Dermatome Map Of Head By Annie Campbell University Of Du Flickr – If you’ve ever wanted to know how the human dermatome chart looks, you’ve come to the right place. Before we go to our map, we’ll take a look at what a dermatome is. What are the various types? And most importantly, what is the reason to learn about dermatomes in order to comprehend the human body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes can help doctors to construct images of spinal cord, which aid in the diagnosis. Two major maps are regarded as valid by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still commonly used. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.
Dermatomes are skin areas that connect to a particular nerve bundle. In cases of spinal cord injury, pain can be felt in a dermatome which 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 are experiencing neurologic condition or pain that involves the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is provided by only one spinal nerve. These nerves carry sensory, motor, and autonomic signals. They form a part of the peripheral nerve system, which connects the brain with the other parts of the body. Dermatomes can become affected due to a spinal lesion. When one of these dermatomes gets injured, it is able to be treated easily with a local anesthetic.
The dermatomes of the thoracic region have been labeled by letter-number combinations, which show the relationship between the area along with the sensor nerve that serves the area. For instance, the C1 spinal nerve does not have a dermatome, but the other spinal nerves are identified as C1-C8 T9, which corresponds with the belly button. Dermatomes are layered vertically on the trunk while dermatomes on the extremities tend to be longitudinal.
Dermatome Map
Dermatome maps are an integral part of textbooks teaching anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. The names are inconsistent, and some textbooks feature different maps on different pages. This is particularly problematic in the event that the authors of various chapters do not agree on the selection of dermatome map. Many textbooks use the maps of Foerster, Keegan, and Garrett however, they do not provide adequate references. Furthermore, four textbooks make use of maps without citations, including one that cites only secondary sources.
The dermatome is the area of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly situated, but they tend to dip more inferiorly than horizontally. This is an inherent variation and some tissue types are covered with more than one. In addition to this, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons that originate from those limbs that are dorsal.
