Dermatomes And Myotomes Sensation Anatomy Geeky Medics – If you have ever wondered how the human dermatome map will look, you’re in the right place. Before we get to the map, let’s take a look at what is a dermatome. What are the different kinds? And most importantly, why is it important to know about dermatomes in order to comprehend the human body. Continue reading to learn 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 spinal cord. Dermatomes can help doctors to construct models of the cord that aid in the diagnosis. Two major maps are regarded as valid by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are often employed. The trigeminal and maxillary nerves are the two largest dermatomes.
Dermatomes are skin-like areas that are linked to a specific nerve bundle. In the case of spinal cord injury, pain can be felt in a dermatome that is connected to that nerve. In the same way, the pain triggered by shingles outbreaks can be felt in specific spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by only one spinal nerve. The nerves transmit motor, sensory as well as autonomic information. They form part of the peripheral nerve system which connects the brain and all the body. Dermatomes can become affected due to a spinal lesion. If one of these dermatomes gets injured, it is able to be easily treated with a local anesthetic.
The dermatomes of the thoracic region are labeled using letter-number sequences that demonstrate how the region is connected along with the sensor nerve that is responsible for that region. For instance C1’s spinal nerve doesn’t have a dematome, however others spinal nerves have been labeled C1 – C8 and T9 refers to the belly button. Dermatomes are layered horizontally along the trunk, while dermatomes that are located on the extremities are generally linear.
Dermatome Map
The dermatome map is a common feature of textbooks that teach anatomy. The dermatome map is inconsistency both within and inter-textbook. The name is not consistent, and some textbooks feature various maps on different pages. This is especially problematic when the authors of multiple chapters do not agree on the selection of dermatome map. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide proper references. Furthermore, four textbooks make use of 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 root of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip lower than horizontally. This is a natural variation and some tissues are covered by more than one dermatome. Also dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons that originate from Dorsal limbs.
