Before we move on to this map, lets look at what a dermatome actually is. What are the different kinds? And, most importantly, why is it essential to be aware of dermatomes order to know more about how the body works. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that covers the spine. Dermatomes can help doctors to develop diagrams of the spine, which help in diagnosing. Two major maps are accepted by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are frequently used. The trigeminal nerve and the maxillary nerve are the largest dermatomes.
Dermatomes are skin regions that are linked to a specific nerve. In cases of spinal injuries, pain may be experienced in a dermatome that is innervated by that nerve. Similarly, the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you suffer from nerve pain or neurological problem affecting the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by a single spinal nerve. The nerves transmit sensory, motor and autonomic messages. They form part of the peripheral nerve system, which connects the brain with the other parts of the body. Dermatomes can become affected due to a spinal cord lesion. If one of these dermatomes is injured, it can be easily treated with local anesthetic.
Dermatomes in the thoracic region have been labeled using letter-number sequences that demonstrate the connection between the region in question and the sensory nerve which supplies this area. For example, the C1 spinal nerve does not have a dermatome, but all spinal nerves in the region are identified as C1-C8 and T9 refers to the belly button. Dermatomes are laid vertically on the trunk however, dermatomes on the extremities tend to be in a longitudinal.
Dermatome Map
The dermatome map is a common feature of textbooks teaching anatomy. The dermatome map is not consistent both within and inter-textbook. Its naming is inconsistent, and some textbooks feature various maps on different pages. This is particularly problematic when the authors of multiple chapters disagree on the choice of dermatome maps. Many textbooks use the Maps of Foerster, Keegan, and Garrett however they don’t provide proper references. In addition, four textbooks utilize maps that do not have citations, such as one that refers to only secondary sources.
Dermatomes are the areas of skin that receives sensory input from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip lower than horizontally. This is a natural variation and some tissues may be covered by multiple dermatomes. Furthermore dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons from Dorsal limbs.
