Dermatomes And Myotomes Anatomy Geeky Medics – If you’ve ever wondered how the human dermatome map looks, you’ve come to the right place. Before we get to this map, lets look at what a dermatome is. What are the different kinds? Most importantly, why is it important to know about dermatomes in order to comprehend the human body. Read on to find out more. You may 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 develop diagrams of the spine, which help in diagnosing. Two major maps are recognized by medical professionals. The Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are commonly utilized. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin regions that connect to a particular nerve. When there is a spinal cord injury, the pain could be felt in a dermatome, which is connected to that nerve. In the same way, the pain triggered by an outbreak of shingles is felt by specific spinal nerves. If you suffer from discomfort or neurological issue involving the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by one spinal nerve. These nerves carry sensory, motor and autonomic information. They form part of the peripheral nerve system which connects the brain with the all the body. Dermatomes can become affected due to a spinal cord lesion. If one of these dermatomes gets injured, it is able to be easily treated using an local anesthetic.
The dermatomes of the thoracic region are labeled with letter-number combinations that show how the region is connected in question and the sensory nerve that serves that area. For example C1’s spinal nerve does not have a dermatome. However, those spinal nerves that are labeled C1-C8 and T9 is a reference to the belly button. Dermatomes are layered in vertically on the trunk and dermatomes located that are located on the extremities are generally linear.
Dermatome Map
The dermatome map is the most common element in textbooks that teach anatomy. The dermatome map is not uniform both inside and inter-textbook. The names are inconsistent as are some textbooks that have distinct maps on different pages. This is especially problematic when the authors of multiple chapters do not agree on the selection of dermatome map. Most textbooks use Maps of Foerster, Keegan, and Garrett however, they do not provide the proper references. Furthermore, four textbooks make use of maps with no citations. This includes one that only cites secondary sources.
The dermatome is the area of skin that receives sensory innervation from the dorsal branch of one spinal nerve. Dermatomes aren’t uniformly placed, however they tend to be more inferior than horizontally. This is an inherent variation and some tissues may be covered by multiple dermatomes. Also, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal limbs.
