Dermatomes And Myotomes Anatomy Geeky Medics – If you have ever wondered what the human dermatome map appears, then you’re at the right place. Before we go to this map, lets discuss what a dermatome is. What are the different kinds? Most importantly, why is it important to know about dermatomes in order to know more about our body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes help doctors to develop images of spinal cord that help in diagnosing. Two maps are widely accepted by medical experts. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are frequently used. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin regions that connect to a particular nerve. In cases of spinal cord injury, pain can be felt in a dermatome which is controlled by the nerve. The same is true for the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you experience a nerve pain or neurological problem affecting the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is provided by only one spinal nerve. These nerves carry motor, sensory, and autonomic messages. They form part of the peripheral nerve system, which connects the brain with the other parts of the body. A dermatome may become affected due to a spinal cord injury. If one of these dermatomes becomes injured, it could be easily treated with a local anesthetic.
Dermatomes in the thoracic region are identified using letter-number sequences that demonstrate how the region is connected as well as the nerve which supplies the area. For example C1 spinal nerve does not have a dermatome, but those spinal nerves that are labeled C1 – C8 and T9 is a reference to belly button. Dermatomes are layered horizontally along the trunk, while dermatomes in the extremities are usually in a longitudinal.
Dermatome Map
The dermatome map is one of the common features of textbooks that cover anatomy. The dermatome map is inconsistent both intra and inter-textbook. Its naming is inconsistent and certain textbooks have different maps on different pages. This is especially problematic when the authors of several chapters differ in their choice of dermatome map. A majority of textbooks employ the map of Foerster, Keegan, and Garrett but don’t include appropriate references. In addition, four textbooks utilize maps with no citations. This includes one that cites only secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal branch of one spinal nerve. The dermatomes are not uniformly found, but they tend to dip more inferiorly than horizontally. This is a natural variation and certain tissues have more than one. Furthermore dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons of the dorsal parts of the limbs.
