Dermatomes And Myotomes – If you have ever wondered how the human dermatome chart will look, you’re in the right place. Before we get to an image, it’s important to talk about what is a dermatome. What are the various types? And, most importantly, why is it essential to know about dermatomes in order to know more about your body. Continue reading to learn more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes are important in allowing doctors to construct images of spinal cord, which can be useful in diagnosing. Two major maps are recognized by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain frequently used. The trigeminal and maxillary nerve are the largest dermatomes.
Dermatomes are areas of skin that connect to a specific nerve. In the case of spinal cord injury, pain can be experienced in a dermatome that is surrounded by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is provided by one spinal nerve. The nerves transmit sensory, motor, and autonomic signals. They form a part of the peripheral nerve system, which connects the brain with the rest of the body. A dermatome may get affected because of a spinal cord lesion. When one of these dermatomes is injured, it can be treated easily with an local anesthetic.
Dermatomes in the thoracic region are labeled with letters-numbers that illustrate the connection between the region and the sensory nerve that is responsible for the area. For example C1’s spinal nerve doesn’t have a dematome, however those spinal nerves that are labeled as C1-C8 and T9 refers to the belly button. Dermatomes are layered in horizontally along the trunk, and dermatomes located in the extremities are usually in a longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks that teach anatomy. However, the dermatome maps is not consistent both within and inter-textbook. Its name isn’t consistent as are some textbooks that have different maps on different pages. This can be particularly challenging when the authors of multiple chapters differ in their choice of dermatome maps. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett but do not include proper references. In addition, four textbooks utilize maps that do not have citations, such as one that uses only secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly situated, but they tend to dip more inferiorly than horizontally. This is an inherent variation and some tissue types are covered with more than one. In addition to this dorsal spinal rootlets could have intrathecal intersegmental anastomoses to sensory neurons of the dorsal limbs.
