Dermatomes Neurology Medbullets Step 1 – If you have ever wondered how the human dermatome chart is, you’ve come to the right spot. Before we move on to our map, we’ll look at what a dermatome is. What are the different types? And, most importantly, why is it essential to learn about dermatomes in order to know more about your 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 is a part of your spinal cord. Dermatomes can help physicians to build images of spinal cord that aid in the diagnosis. Two major maps are accepted by medical professionals. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and remain commonly employed. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that are attached to a specific nerve. In the case of spinal cord injuries, pain may be felt in a dermatome, which is controlled by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you experience a neurologic condition or pain that involves the dermatome, you should consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin supplied by only one spinal nerve. These nerves relay sensory, motor, and autonomic signals. They form an element of the peripheral nerve system, which connects the brain and all the body. A dermatome may become affected due to a spinal cord lesion. When one of these dermatomes gets injured, it is able to be easily treated with an local anesthetic.
Dermatomes in the thoracic region are labeled with letters-numbers that illustrate the connection between the region as well as the nerve that is responsible for that region. For example, the C1 spinal nerve does not have a dermatome. However, others spinal nerves have been labeled C1 – C8 and T9 refers to the belly button. Dermatomes are layered in horizontally along the trunk, and dermatomes located on the extremities tend to be in a longitudinal.
Dermatome Map
The dermatome map is a common feature of textbooks that teach anatomy. The dermatome map is inconsistency both within and inter-textbook. Its name isn’t consistent, and some textbooks feature various maps on different pages. This is particularly problematic in the event that the authors of various chapters disagree on the choice of dermatome map. The majority of textbooks utilize the maps of Foerster, Keegan, and Garrett however, they do not provide the proper references. Additionally, four textbooks employ maps that do not have citations, such as one that only cites secondary sources.
The dermatome is the area of skin that receives sensory innervation from the dorsal branch of one spinal nerve. Dermatomes aren’t uniformly placed, however they tend to be more inferior than horizontally. This is an inherent variation and some tissues may be covered by multiple dermatomes. Furthermore dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons of Dorsal limbs.
