Dermatome Map Overview Chart Anatomy Clinical Significance – If you’ve ever wanted to know what the human dermatome map appears, then you’re at the right spot. Before we look at our map, we’ll take a look at the definition of a dermatome. What are the different kinds? And most importantly, what is the reason to understand dermatomes in order to know more about how the body works. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers your spinal cord. Dermatomes help physicians to build models of the cord, which aid in the diagnosis. Two major maps are recognized by medical professionals. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain often employed. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin-like areas that connect to a particular nerve bundle. In the case of spinal cord injuries, pain may be felt in a dermatome that is surrounded by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt in specific spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by a single spinal nerve. These nerves carry motor, sensory, and autonomic signals. They form part of the peripheral nervous system which connects brain and rest of the body. Dermatomes can become affected due to a spinal cord injury. When one of these dermatomes is injured, it can be easily treated with a local anesthetic.
The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate the connection between the area along with the sensor nerve that is responsible for that area. For example C1 spinal nerve does not have a dematome, however those spinal nerves that are labeled C1 – C8, while T9 corresponds to belly button. Dermatomes are laid horizontally along the trunk, those on the extremities tend to be linear.
Dermatome Map
The dermatome map is the most common element in textbooks teaching anatomy. But, the map is inconsistency both within and inter-textbook. Its naming is inconsistent as are some textbooks that have distinct maps on different pages. This is especially problematic when the authors of multiple chapters are not unified in their choice of dermatome maps. Many textbooks use the maps of Foerster, Keegan, and Garrett but do not include the proper references. Furthermore, four textbooks make use of maps with no citations. This includes one that cites only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal root of a spinal nerve. The dermatomes are not uniformly found, but they tend to dip more inferiorly than horizontally. This is a normal variation and certain tissues have more than one. In addition to this dorsal spinal rootlets could have intrathecal intersegmental anastomoses with sensory neurons in the dorsal parts of the limbs.
