Before we move on to our map, we’ll talk about the definition of a dermatome. What are the various kinds? And most importantly, why is it necessary to be aware of dermatomes order to better understand your body. Continue reading to learn more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes are important in allowing physicians to build images of spinal cord, which aid in the diagnosis. Two major maps are regarded as valid by medical professionals. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s, and are frequently employed. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin-like areas that are linked to a specific nerve. In cases of spinal injury, pain can be felt in a dermatome that is controlled by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you feel nerve pain or neurological problem affecting the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by one spinal nerve. These nerves carry motor, sensory and autonomic signals. They form part of the peripheral nervous system, that connects the brain to the all the body. Dermatomes can be affected by a spinal cord lesion. If one of these becomes injured, it can be easily treated with the use of a local anesthetic.
Dermatomes in the thoracic region are labeled with letter-number combinations that show the relationship between the area in question and the sensory nerve that is responsible for that area. For instance C1’s spinal nerve doesn’t have a dematome, however those spinal nerves that are labeled C1 – C8 and T9 refers to the belly button. Dermatomes are layered vertically on the trunk while dermatomes in the extremities are usually linear.
Dermatome Map
Dermatome maps are an integral part of textbooks that teach anatomy. The dermatome map is inconsistent both intra and inter-textbook. The name is not consistent, and some textbooks feature different maps on different pages. This can be particularly challenging in the event that the authors of various chapters are not unified in their choice of dermatome map. Most textbooks use map of Foerster, Keegan, and Garrett however they don’t provide proper references. Moreover, four textbooks use maps with no citations. This includes one that only cites secondary sources.
The dermatome is the area of skin that receives sensory input from the dorsal branch of one spinal nerve. Dermatomes aren’t always 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. Also, dorsal spinal rootlets may contain intrathecal intersegmental connections with sensory neurons of those limbs that are dorsal.
