Posterior Dermatome Map QxMD – If you’ve ever wanted to know what the human dermatome map appears, then you’re at the right spot. Before we get to this map, lets take a look at what a dermatome actually is. What are the various types? The most important thing is why is it important to be aware of dermatomes order to understand how the body works. Read on to find out more. You may be surprised! Here are some examples of dermatomes.
What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes help physicians to build maps of the spinal cord, which aid in the diagnosis. Two major maps are regarded as valid by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are widely used. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are areas of skin which are connected to a particular nerve bundle. In cases of spinal cord injury, the pain could be felt in a dermatome which is connected to that nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in particular spinal nerves. If you feel discomfort or neurological issue involving the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by the spinal nerve. The nerves transmit sensory, motor, and autonomic signals. They form an element of the peripheral nerve system, that connects the brain to the other parts of the body. A dermatome may get affected because of a spinal lesion. If one of these dermatomes is injured, it can be treated easily with a local anesthetic.
Dermatomes in the thoracic region are labeled with letters-numbers that illustrate the relationship between the area and the sensory nerve that is responsible for the area. For instance C1’s spinal nerve does not have a dermatome, but the other spinal nerves are labeled as C1-C8 and T9 is a reference with the belly button. Dermatomes are layered horizontally on the trunk and dermatomes located in the extremities are usually linear.
Dermatome Map
The dermatome map is the most common element in textbooks that cover anatomy. However, the dermatome map is not uniform both inside and inter-textbook. Its naming is inconsistent and some textbooks include various maps on different pages. This is particularly problematic in the event that the authors of various chapters are not unified in their choice of dermatome map. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett but do not include the proper references. Furthermore, four textbooks make use of maps that do not have citations, such as one that refers to only secondary sources.
Dermatomes are the areas of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly found, but they tend to be more inferior than horizontally. This is a natural variation, and some tissues are covered by more than one dermatome. Furthermore dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons in those limbs that are dorsal.
