Dermatomes Ndash Mycerebellarstrokerecovery Medical Tech Historical – If you’ve ever thought about what the human dermatome map looks, you’ve come to the right spot. Before we get to this map, lets take a look at the definition of a dermatome. What are the different kinds? Most importantly, what is the reason to understand 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 is a part of the spinal cord. Dermatomes can help physicians to build images of spinal cord that help in diagnosing. Two major maps are recognized by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are often used. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin regions that connect to a particular nerve bundle. In the case of spinal cord injury, the pain could be felt in a dermatome that is innervated by that nerve. The same is true for the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you feel nerve pain or neurological problem affecting the dermatome area, you must visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by a single spinal nerve. These nerves provide motor, sensory, and autonomic messages. They form an element of the peripheral nerve system, which connects the brain and rest of the body. A dermatome may become affected due to a spinal cord lesion. If one of these becomes injured, it can be easily treated with an local anesthetic.
The dermatomes of the thoracic region are identified with letter-number combinations that show the relationship between the area in question and the sensory nerve that supplies that region. For instance C1 spinal nerve does not have a dermatome, but others spinal nerves have been labeled as C1-C8 T9, which corresponds to belly button. Dermatomes are layered horizontally on the trunk and dermatomes located on the extremities tend to be linear.
Dermatome Map
The dermatome map is one of the common features of textbooks teaching anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. Its naming is inconsistent, and some textbooks feature different maps on different pages. This is especially problematic when the authors of several chapters disagree on the choice of dermatome map. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett but do not include proper references. Moreover, four textbooks use maps that do not have citations, such as one that cites only secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal root of a spinal nerve. The dermatomes are not uniformly placed, however they tend to dip more inferiorly than horizontally. This is a natural variation, and some tissue types are covered with more than one. Additionally, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons from Dorsal limbs.
