Leg Dermatomes – If you have ever wondered how the human dermatome map is, you’ve come to the right place. Before we go to our map, we’ll look at what a dermatome is. What are the different types? Most importantly, why is it important to learn about dermatomes in order to comprehend the human body. 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 the spine. Dermatomes are important in allowing doctors to construct models of the 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. The maps were designed in the 1930s, and are frequently employed. The trigeminal nerve , as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin areas that are attached to a particular nerve bundle. In the case of spinal cord injury, pain can be felt in a dermatome, which is controlled by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you experience a neurologic condition or pain that involves the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by one spinal nerve. These nerves relay motor, sensory and autonomic signals. They form a part of the peripheral nerve system, which connects brain and all the body. Dermatomes can be affected by a spinal injury. If one of these dermatomes becomes injured, it could be easily treated using a local anesthetic.
Dermatomes in the thoracic region are identified with letters-numbers that illustrate the connection between the region as well as the nerve which supplies that area. For instance C1’s spinal nerve does not have a dermatome. However, all spinal nerves in the region are labeled C1-C8 and T9 is a reference with the belly button. Dermatomes are layered horizontally on the trunk, those on the extremities tend to be long.
Dermatome Map
Dermatome maps are one of the common features of textbooks that cover anatomy. But, the map is not consistent both within and inter-textbook. Its name isn’t consistent and some textbooks include different maps on various pages. This can be particularly challenging when the authors of different chapters are not unified in their choice of dermatome maps. Most textbooks use maps of Foerster, Keegan, and Garrett however, they do not provide the proper references. Additionally, four textbooks employ maps with no citations. This includes one that cites only secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation 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 natural variation and certain tissues may be covered by multiple dermatomes. In addition to this dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons in those limbs that are dorsal.
