Cervical Dermatome Map Physical Therapy Hand Therapy Massage Therapy – If you’ve ever thought about what the human dermatome’s map looks, you’ve come to the right spot. Before we get to the map, let’s discuss what a dermatome actually is. What are the various types? The most important thing is what is the reason to learn about dermatomes in order to understand the human body. Read on to find out more. You might be surprised! Here are some examples of dermatomes.
What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes are important in allowing doctors to create diagrams of the spine, which are useful for diagnosis. Two major maps are regarded as valid by medical professionals. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are widely employed. The trigeminal and maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that connect to a specific nerve bundle. In cases of spinal injury, pain can be felt in a dermatome that is innervated by that nerve. In the same way, the pain triggered by shingles outbreaks can be felt in specific spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome, it is recommended that you see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is provided by only one spinal nerve. These nerves provide motor, sensory, as well as autonomic information. They form part of the peripheral nervous system which connects the brain and other parts of the body. Dermatomes can be affected by a spinal cord injury. If one of these gets injured, it is able to be easily treated using the use of a local anesthetic.
Dermatomes in the thoracic area are marked using letter-number sequences that demonstrate the connection between the region and the sensory nerve that is responsible for the area. For example the C1 spinal nerve doesn’t have a dematome, however the other spinal nerves are labeled C1-C8 and T9 refers to the belly button. Dermatomes are layered vertically on the trunk those that are located on the extremities are generally linear.
Dermatome Map
Dermatome maps are an integral part of textbooks that cover anatomy. But, the map is not consistent both within and inter-textbook. The names are inconsistent and certain textbooks have different maps on various pages. This is especially problematic in the event that the authors of various chapters are not unified in their choice of dermatome map. Many textbooks use the maps of Foerster, Keegan, and Garrett but do not include the proper references. Moreover, four textbooks use maps without citations, including 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 dip lower than horizontally. This is a normal variation and certain tissues are covered by more than one dermatome. Furthermore dorsal spinal rootlets could contain intrathecal intersegmental connections with sensory neurons from the dorsal parts of the limbs.
