Before we look at this map, lets look at the definition of a dermatome. What are the different types? And, most importantly, what is the reason to understand dermatomes in order to better understand 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 can help physicians to build images of spinal cord that aid in the diagnosis. Two maps are widely accepted by medical specialists. These are: 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 areas of skin that are linked to a specific nerve. In cases of spinal injury, pain may be felt in a dermatome, which is connected to that nerve. Similarly, the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome region, you need to consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by one spinal nerve. These nerves carry sensory, motor as well as autonomic information. They form part of the peripheral nervous system, which connects the brain with the all the body. A dermatome may suffer from a spinal lesion. If one of these dermatomes gets injured, it is able to be treated easily with 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 this area. For example C1 spinal nerve doesn’t possess a dermatome, however those spinal nerves that are labeled C1 – C8 and T9 is a reference to the belly button. Dermatomes are laid horizontally on the trunk, however, dermatomes on the extremities are typically in a longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks that teach anatomy. But, the map is inconsistent both intra and inter-textbook. Its name isn’t consistent and some textbooks include distinct maps on different pages. This is especially problematic when the authors of different chapters differ in their choice of dermatome map. Most textbooks use maps of Foerster, Keegan, and Garrett however they don’t provide appropriate references. Moreover, four textbooks use maps with no citations. This includes one that refers to only secondary sources.
The dermatome is the area of skin that receives sensory input from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to be more inferior than horizontally. This is a normal variation and certain tissues may be covered by multiple dermatomes. Also dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons from those limbs that are dorsal.
