Cervical Lumbar Dermatomes Map Of Upper Lower Body Leg Limbs Head – If you’ve ever wanted to know how the human dermatome map appears, then you’re at the right place. Before we get to an image, it’s important to take a look at what is a dermatome. What are the various kinds? Most importantly, why is it important to know about dermatomes in order to better understand how the body works. 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 cord of the spinal. Dermatomes can help doctors to construct diagrams of the spine that aid in the diagnosis. Two maps are widely accepted by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are commonly utilized. The trigeminal nerve , as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are areas of skin that are linked to a specific nerve. In the case of spinal cord injury, the pain could be felt in a dermatome that is controlled by the nerve. In the same way, the pain triggered by shingles outbreaks is felt by specific spinal nerves. If you are experiencing nerve pain or neurological problem affecting the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by only one spinal nerve. These nerves relay sensory, motor and autonomic information. They form an element of the peripheral nervous system which connects the brain with the other parts of the body. Dermatomes can get affected because of a spinal cord injury. If one of these dermatomes becomes injured, it can be easily treated using the use of a local anesthetic.
Dermatomes in the thoracic area are marked with letters-numbers that illustrate the connection between the region as well as the nerve that supplies this area. For instance C1 spinal nerve doesn’t possess a dermatome, however all spinal nerves in the region are labeled C1 – C8 and T9 is a reference to belly button. Dermatomes are layered vertically on the trunk however, dermatomes in the extremities are usually linear.
Dermatome Map
Dermatome maps are one of the common features of textbooks that cover anatomy. But, the map is not uniform both inside and inter-textbook. Its naming is inconsistent as are some textbooks that have different maps on different pages. This is particularly problematic when the authors of multiple chapters disagree on the choice of dermatome map. Most textbooks use Maps of Foerster, Keegan, and Garrett however, they do not provide appropriate references. Additionally, four textbooks employ maps with no citations. This includes one that uses only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip more inferiorly than horizontally. This is a natural variation, and some tissues have more than one. Furthermore, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons in those limbs that are dorsal.
