Before we move on to an image, it’s important to look at the definition of a dermatome. What are the different kinds? And most importantly, what is the reason to be aware of dermatomes order to comprehend the human body. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.
What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes play a crucial role in allowing doctors to create diagrams of the spine, which help in diagnosing. Two major maps are accepted by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still often employed. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas that connect to a specific nerve. In cases of spinal cord injury, the pain could be felt in a dermatome which is surrounded by the nerve. Similar to the pain that is caused by an outbreak of shingles is felt by specific spinal nerves. If you are experiencing pain or neurological condition involving the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by a single spinal nerve. These nerves carry sensory, motor and autonomic information. They form an element of the peripheral nervous system that connects the brain to the other parts of the body. A dermatome may get affected because of a spinal lesion. If one of these dermatomes becomes injured, it can be treated easily with local anesthetic.
Dermatomes in the thoracic area are marked with letters-numbers that illustrate the connection between the region as well as the nerve that serves that region. For example, the C1 spinal nerve doesn’t have a dermatome, but the other spinal nerves are labeled C1-C8 T9, which corresponds with the belly button. Dermatomes are laid horizontally on the trunk, those on the extremities tend to be linear.
Dermatome Map
Dermatome maps are the most common element in textbooks teaching anatomy. But, the map is inconsistency both within and inter-textbook. The names are inconsistent, and some textbooks feature distinct maps on different pages. This is particularly problematic when the authors of several chapters differ in their choice of dermatome maps. A majority of textbooks employ the Maps of Foerster, Keegan, and Garrett but don’t include proper references. Additionally, four textbooks employ maps that do not have citations, such as one that refers to only secondary sources.
The dermatome is the area of skin that receives sensory input from the dorsal root of a spinal nerve. The dermatomes are not uniformly situated, but they tend to dip less inferiorly than horizontally. This is a natural 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.
