Dermatomes And Myotomes Anatomy Geeky Medics – If you’ve ever thought about what the human dermatome’s map is, you’ve come to the right place. Before we move on to the map, let’s take a look at what is a dermatome. What are the various kinds? And, most importantly, why is it necessary to be aware of dermatomes order to better understand our body. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers the spine. Dermatomes can help doctors to construct images of spinal cord, which aid in the diagnosis. Two major maps are recognized by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are often used. The trigeminal and maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin regions which are connected to a specific nerve bundle. In cases of spinal cord injury, the pain could be felt in a dermatome which is surrounded by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt in particular spinal nerves. If you are experiencing pain or neurological condition involving the dermatome, it is recommended that you visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by only one spinal nerve. The nerves transmit sensory, motor and autonomic messages. They form an element of the peripheral nervous system which connects brain and all the body. Dermatomes can become affected due to a spinal lesion. If one of these dermatomes becomes injured, it could be treated easily with an local anesthetic.
Dermatomes in the thoracic region have been labeled with letters-numbers that illustrate the connection between the region in question and the sensory nerve that supplies that region. For example, the C1 spinal nerve doesn’t have a dematome, however the other spinal nerves are identified as C1-C8 T9, which corresponds to belly button. Dermatomes are laid horizontally on the trunk, however, dermatomes in the extremities are usually in a longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks teaching anatomy. The dermatome map is not uniform both inside and inter-textbook. The name is not consistent as are some textbooks that have different maps on various pages. This can be particularly challenging when the authors of different chapters are not unified in their choice of dermatome maps. Many textbooks use the map of Foerster, Keegan, and Garrett but don’t include proper references. Additionally, four textbooks employ maps that do not have citations, such as one that refers to only secondary sources.
Dermatomes are the parts of skin that receives sensory innervation from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip more inferiorly than horizontally. This is a natural variation, and some tissues are covered by more than one dermatome. In addition to this dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons in the dorsal limbs.
