Before we look at this map, lets discuss what a dermatome is. What are the different types? And most importantly, why is it important to understand dermatomes in order to better understand the human body. Continue reading to learn more. You might be amazed!

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 images of spinal cord that help in diagnosing. Two major maps are recognized by medical specialists. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still frequently used. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.
Dermatomes are areas of skin that are linked to a particular nerve. In cases of spinal injury, the pain could be felt in a dermatome that is surrounded by the nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in specific spinal nerves. If you are experiencing nerve pain or neurological problem affecting the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by the spinal nerve. The nerves transmit motor, sensory, as well as autonomic information. They form part of the peripheral nervous system which connects the brain and all the body. A dermatome may become affected due to a spinal cord injury. If one of these dermatomes becomes injured, it could be treated easily with the use of a local anesthetic.
The dermatomes of the thoracic region are labeled using letter-number sequences that demonstrate the relationship between the area along with the sensor nerve that supplies that region. For example, the C1 spinal nerve does not have a dermatome. However, all spinal nerves in the region are identified as C1-C8 and T9 is a reference to belly button. Dermatomes are laid horizontally on the trunk those that are located on the extremities are generally linear.
Dermatome Map
Dermatome maps are an integral part of textbooks that teach anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. Its name isn’t consistent and some textbooks include various maps on different pages. This is particularly problematic when the authors of several chapters are not unified in their choice of dermatome map. The majority of textbooks utilize the maps of Foerster, Keegan, and Garrett however, they do not provide the proper references. In addition, four textbooks utilize maps that do not have citations, such as one that uses only secondary sources.
The dermatome is the area of skin that receives sensory innervation from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly found, but they tend to dip less inferiorly than horizontally. This is a normal variation and certain tissues are covered by more than one dermatome. Additionally, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons from the dorsal limbs.
