Dermatomes And Myotomes Anatomy Geeky Medics – If you’ve ever wanted to know what the human dermatome’s map looks, you’ve come to the right spot. Before we move on to the map, let’s discuss what is a dermatome. What are the various kinds? Most importantly, what is the reason to be aware of dermatomes order to comprehend how the body works. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the spine. Dermatomes can help physicians to build images of spinal cord that aid in the diagnosis. Two major maps are accepted by medical specialists. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still frequently used. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas that are linked to a particular nerve bundle. In cases of spinal injury, pain can be felt in a dermatome which is innervated by that nerve. In the same way, the pain triggered by an outbreak of shingles is felt by specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is supplied by the spinal nerve. The nerves transmit sensory, motor and autonomic information. They form a part of the peripheral nervous system which connects the brain with the other parts of the body. A dermatome may become affected due to a spinal injury. When one of these dermatomes gets injured, it is able to be easily treated using an local anesthetic.
The dermatomes of the thoracic region are identified by letter-number combinations, which show how the region is connected along with the sensor nerve that supplies the area. For example C1 spinal nerve doesn’t have a dermatome. However, the other spinal nerves are labeled as C1-C8 T9, which corresponds to the belly button. Dermatomes are layered horizontally along the trunk, while dermatomes on the extremities are typically long.
Dermatome Map
Dermatome maps are a common feature of textbooks teaching anatomy. However, the dermatome maps is not consistent both within and inter-textbook. Its name isn’t consistent, and some textbooks feature various maps on different pages. This can be particularly challenging when the authors of multiple chapters do not agree on the selection of dermatome maps. The majority of textbooks utilize the map of Foerster, Keegan, and Garrett but don’t include appropriate references. In addition, four textbooks utilize maps with no citations. This includes one that cites only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip lower than horizontally. This is a normal variation and some tissues are covered by more than one dermatome. Additionally, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal parts of the limbs.
