Before we look at this map, lets discuss what is a dermatome. What are the different kinds? The most important thing is why is it necessary to learn about dermatomes in order to better understand the human body. Read on to find out 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 can help doctors to create maps of the spinal cord, which are useful for diagnosis. 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 are still widely employed. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are areas of skin that connect to a particular nerve. In cases of spinal cord injury, pain can be felt in a dermatome that is surrounded by the nerve. The same is true for the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you feel discomfort or neurological issue involving the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by only one spinal nerve. These nerves carry motor, sensory, and autonomic signals. They form a part of the peripheral nerve system, which connects the brain and other parts of the body. A dermatome may be affected by a spinal cord lesion. When one of these dermatomes becomes injured, it can be treated easily with the use of a local anesthetic.
The dermatomes of the thoracic area are marked using letter-number sequences that demonstrate the connection between the region along with the sensor nerve which supplies the area. For instance the C1 spinal nerve doesn’t possess a dermatome, however the other spinal nerves are labeled as C1-C8 T9, which corresponds with the belly button. Dermatomes are layered in vertically on the trunk while dermatomes on the extremities tend to be linear.
Dermatome Map
Dermatome maps are one of the common features of textbooks that teach anatomy. However, the dermatome map is not consistent both within and inter-textbook. The name is not consistent, and some textbooks feature distinct maps on different pages. This is particularly problematic in the event that the authors of various chapters are not unified in their choice of dermatome maps. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide proper references. In addition, four textbooks utilize maps without citations, including one that uses only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip less inferiorly than horizontally. This is a natural variation and some tissues have more than one. Furthermore dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons from those limbs that are dorsal.
