Dermatomes And Myotomes Anatomy Geeky Medics – If you have ever wondered how the human dermatome map appears, then you’re at the right spot. Before we get to the map, let’s talk about what is a dermatome. What are the various kinds? Most importantly, why is it important to understand dermatomes in order to better understand your body. 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 your spinal cord. Dermatomes can help doctors to construct images of spinal cord, which help in diagnosing. Two major maps are regarded as valid by medical specialists. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are widely utilized. The trigeminal and maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin regions that connect to a particular nerve bundle. When there is a spinal cord injury, pain can be felt in a dermatome which is surrounded by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt on specific spinal nerves. If you are experiencing pain or neurological condition involving the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by the spinal nerve. The nerves transmit motor, sensory and autonomic information. They form part of the peripheral nervous system which connects the brain with the rest of the body. Dermatomes can suffer from a spinal cord lesion. When one of these dermatomes is injured, it can be easily treated using the use of a local anesthetic.
Dermatomes in the thoracic region are labeled by letter-number combinations, which show the connection between the region along with the sensor nerve that is responsible for that area. For instance the C1 spinal nerve does not have a dermatome, but those spinal nerves that are identified as C1-C8, while T9 corresponds with the belly button. Dermatomes are laid horizontally on the trunk, those on the extremities are typically longitudinal.
Dermatome Map
The dermatome map is a common feature of textbooks teaching anatomy. However, the dermatome maps is not consistent both within and inter-textbook. Its naming is inconsistent and some textbooks include distinct maps on different pages. This can be particularly challenging when the authors of multiple 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 adequate references. Additionally, four textbooks employ maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly located, but they tend to dip less inferiorly than horizontally. This is a normal variation and certain tissues may be covered by multiple dermatomes. In addition to this dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons from the dorsal limbs.
