Dermatomes And Myotomes Anatomy Geeky Medics – If you’ve ever wanted to know what the human dermatome map appears, then you’re at the right place. Before we move on to the map, let’s discuss what a dermatome is. What are the various kinds? And most importantly, why is it important to understand 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?
“dermatome” or “dermatome” refers to a tissue that is a part of the spine. Dermatomes help doctors to develop models of the cord that help in diagnosing. Two major maps are accepted by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are often utilized. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that connect to a specific nerve bundle. In cases of spinal injuries, pain may be felt in a dermatome which is controlled by the nerve. Similarly, the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you experience a neurologic condition or pain that involves the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by one spinal nerve. These nerves relay motor, sensory, as well as autonomic information. They form part of the peripheral nerve system, which connects brain and other parts of the body. A dermatome may get affected because of a spinal lesion. When one of these dermatomes gets injured, it is able to be treated easily with a local anesthetic.
The dermatomes of the thoracic region are labeled by letter-number combinations, which show how the region is connected along with the sensor nerve which supplies that region. For instance the C1 spinal nerve doesn’t have a dermatome. However, those spinal nerves that are labeled C1 – C8 and T9 is a reference to belly button. Dermatomes are layered in horizontally on the trunk, those on the extremities are typically in a longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks that teach anatomy. But, the map is not consistent both within and inter-textbook. The name is not consistent, and some textbooks feature different maps on various 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 don’t include proper references. Moreover, four textbooks use maps without citations, including one that uses only secondary sources.
Dermatomes are the regions of skin that receives sensory input from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly placed, however they tend to dip more inferiorly than horizontally. This is an inherent variation and certain tissues may be covered by multiple dermatomes. In addition to this dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons from Dorsal limbs.
