Dermatome Distribution For The Cervical Spine Netter Muscle Anatomy – If you’ve ever wondered what the human dermatome’s map looks, you’ve come to the right place. Before we get to this map, lets take a look at what a dermatome actually is. What are the different kinds? Most importantly, why is it necessary to know about dermatomes in order to know more about how the body works. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.
What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes play a crucial role in allowing doctors to develop maps of the spinal cord, which aid in the diagnosis. Two major maps are recognized by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still often used. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin-like areas that are linked to a specific nerve bundle. In the case of spinal cord injury, the pain could be felt in a dermatome which is controlled by the nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in specific spinal nerves. If you feel neurologic condition or pain that involves the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by the spinal nerve. These nerves provide sensory, motor, and autonomic messages. They form an element of the peripheral nerve system which connects the brain and other parts of the body. A dermatome may suffer from a spinal cord injury. When one of these dermatomes gets injured, it is able to be easily treated using an local anesthetic.
Dermatomes in the thoracic region are labeled using letter-number sequences that demonstrate the connection between the region and the sensory nerve that serves that region. For instance C1’s spinal nerve does not possess a dermatome, however the other spinal nerves are labeled C1 – C8, while T9 corresponds to belly button. Dermatomes are layered in horizontally along the trunk, and dermatomes located on the extremities are typically long.
Dermatome Map
The dermatome map is the most common element in textbooks teaching anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. Its naming is inconsistent as are some textbooks that have various maps on different pages. This is particularly problematic when the authors of multiple chapters disagree on the choice of dermatome map. A majority of textbooks employ the map of Foerster, Keegan, and Garrett but do not include proper references. Moreover, four textbooks use maps without citations, including one that refers to only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t evenly placed, however they tend to be more inferior than horizontally. This is a natural variation, and certain tissues have more than one. In addition to this dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons from the dorsal limbs.
