Before we go to our map, we’ll discuss what a dermatome actually is. What are the different kinds? Most importantly, what is the reason to learn about dermatomes in order to know more about the human body. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the spine. Dermatomes can help doctors to create diagrams of the spine, which can be useful in diagnosing. Two major maps are regarded as valid by medical professionals. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are widely utilized. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that are attached to a specific nerve bundle. In cases of spinal cord injury, pain may be felt in a dermatome that is controlled by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you feel discomfort or neurological issue involving the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by the spinal nerve. These nerves relay motor, sensory, and autonomic messages. They form part of the peripheral nerve system that connects the brain to the rest of the body. A dermatome may suffer from a spinal lesion. If one of these becomes injured, it can be treated easily with a local anesthetic.
The dermatomes of the thoracic region have been labeled by letter-number combinations, which show the connection between the area along with the sensor nerve that supplies this area. For example C1 spinal nerve doesn’t have a dermatome, but all spinal nerves in the region are identified as C1-C8, while T9 corresponds to the belly button. Dermatomes are layered in horizontally on the trunk while dermatomes on the extremities are typically linear.
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 and some textbooks include 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 maps. Many textbooks use the map of Foerster, Keegan, and Garrett however they don’t provide the proper references. Moreover, four textbooks use maps with no citations, and one of them is one that only cites secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly placed, however they tend to dip more inferiorly than horizontally. This is a normal variation and some tissues are covered by more than one dermatome. Additionally, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal limbs.
