What are the various types? The most important thing is why is it important to understand dermatomes in order to comprehend how the body works. Read on to find out more. You may be surprised! Here are some examples of dermatomes.
What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help doctors to create maps of the spinal cord, which are useful for diagnosis. Two major maps are recognized by medical professionals. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are frequently employed. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that are attached to a specific nerve. When there is a spinal cord injuries, pain may be felt in a dermatome which is innervated by that nerve. In the same way, the pain triggered by shingles outbreaks can be felt on specific spinal nerves. If you feel pain or neurological condition involving the dermatome, you should consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by one spinal nerve. The nerves transmit sensory, motor and autonomic messages. They form a part of the peripheral nervous system, that connects the brain to the other parts of the body. A dermatome may get affected because of a spinal injury. If one of these becomes injured, it can be treated easily with a local anesthetic.
Dermatomes in the thoracic region have been labeled using letter-number sequences that demonstrate how the region is connected and the sensory nerve that is responsible for this area. For instance the C1 spinal nerve doesn’t have a dermatome, but others spinal nerves have been labeled C1 – C8 and T9 is a reference to belly button. Dermatomes are laid horizontally along the trunk, those on the extremities are typically linear.
Dermatome Map
Dermatome maps are an integral part of textbooks that cover anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. The names are inconsistent as are some textbooks that have different maps on different pages. This is especially problematic when the authors of multiple chapters disagree on the choice of dermatome map. Many textbooks use the diagrams drawn by Foerster, Keegan, and Garrett but do not include the proper references. Moreover, four textbooks use maps with no citations, and one of them is one that uses only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly located, but they tend to dip lower than horizontally. This is a natural variation and certain tissues may be covered by multiple dermatomes. Furthermore dorsal spinal nerve roots may contain intrathecal intersegmental connections with sensory neurons from those limbs that are dorsal.
