Dermatomes And Myotomes Anatomy Geeky Medics – If you have ever wondered what the human dermatome map is, you’ve come to the right spot. Before we move on to an image, it’s important to take a look at what a dermatome actually is. What are the different kinds? The most important thing is what is the reason to understand dermatomes in order to 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 spinal cord. Dermatomes help doctors to develop diagrams of the spine, which can be useful in diagnosing. Two major maps are recognized by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and remain widely utilized. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.
Dermatomes are areas of skin that connect to a specific nerve. In cases of spinal cord injury, pain may be felt in a dermatome, which is innervated by that nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in specific spinal nerves. If you experience a pain or neurological condition involving the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by only one spinal nerve. The nerves transmit motor, sensory, and autonomic signals. They form a part of the peripheral nerve system which connects the brain and other parts of the body. A dermatome may get affected because of a spinal cord injury. If one of these becomes injured, it could be easily treated using the use of a local anesthetic.
Dermatomes in the thoracic region are identified with letter-number combinations that show how the region is connected along with the sensor nerve that is responsible for the area. For instance the C1 spinal nerve doesn’t possess a dermatome, however the other spinal nerves are labeled C1-C8 and T9 refers with the belly button. Dermatomes are layered in horizontally on the trunk those on the extremities are typically linear.
Dermatome Map
Dermatome maps are a common feature of textbooks that cover anatomy. But, the map is not uniform both inside and inter-textbook. The names are inconsistent and certain textbooks have distinct maps on different pages. This is especially problematic when the authors of several chapters are not unified in their choice of dermatome map. Many textbooks use the Maps of Foerster, Keegan, and Garrett but don’t include appropriate references. Moreover, four textbooks use maps that do not have citations, such as one that refers to only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal branch of one spinal nerve. The dermatomes are not uniformly placed, however they tend to dip more inferiorly than horizontally. This is an inherent variation and certain tissues may be covered by multiple dermatomes. Additionally dorsal spinal rootlets could have intrathecal intersegmental anastomoses with sensory neurons from the dorsal limbs.
