Before we look at the map, let’s take a look at what a dermatome actually is. What are the various types? And most importantly, why is it essential to understand dermatomes in order to comprehend our body. Continue reading to learn 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 cord of the spinal. Dermatomes play a crucial role in allowing doctors to construct images of spinal cord that help in diagnosing. Two major maps are regarded as valid by medical professionals. The Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain often employed. The trigeminal nerve as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are areas of skin which are connected to a particular nerve. In cases of spinal injury, the pain could be felt in a dermatome that is controlled by the nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in particular spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin supplied by the spinal nerve. These nerves relay motor, sensory, and autonomic information. They form a part of the peripheral nerve system that connects the brain to the rest of the body. A dermatome may suffer from a spinal cord lesion. If one of these dermatomes becomes injured, it could be easily treated using an local anesthetic.
The dermatomes of the thoracic region have been labeled using letter-number sequences that demonstrate the connection between the region along with the sensor nerve that supplies that area. For instance C1 spinal nerve doesn’t have a dematome, however the other spinal nerves are labeled C1 – C8 and T9 is a reference with the belly button. Dermatomes are layered horizontally along the trunk, those in the extremities are usually linear.
Dermatome Map
Dermatome maps are one of the common features of textbooks that cover anatomy. But, the map is not uniform both inside and inter-textbook. Its name isn’t consistent and certain textbooks have different maps on various pages. This is especially problematic in the event that the authors of various chapters are not unified in their choice of dermatome map. Many textbooks use the maps of Foerster, Keegan, and Garrett but do not include adequate references. Moreover, four textbooks use maps that do not have citations, such as one that cites only secondary sources.
Dermatomes are the areas of skin that receives sensory innervation from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to be more inferior than horizontally. This is a natural variation and some tissues are covered by more than one dermatome. In addition to this dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons of the dorsal parts of the limbs.
