Skin Dermatome Map – If you’ve ever thought about how the human dermatome chart will look, you’re in the right place. Before we go to our map, we’ll take a look at what is a dermatome. What are the various types? Most importantly, why is it important to understand dermatomes in order to know more about your body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the spine. Dermatomes help doctors to develop maps of the spinal cord that are useful for diagnosis. Two major maps are accepted by medical professionals. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are frequently used. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.

Dermatomes are skin regions that are linked to a particular nerve. In cases of spinal cord injury, pain can be felt in a dermatome which is innervated by that nerve. In the same way, the pain triggered by an outbreak of shingles is felt by specific spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome, you should consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin supplied by only one spinal nerve. These nerves carry motor, sensory, and autonomic signals. They form a part of the peripheral nerve system which connects brain and other parts of the body. Dermatomes can be affected by a spinal cord lesion. If one of these dermatomes gets injured, it is able to be easily treated with local anesthetic.

The dermatomes of the thoracic region are identified with letters-numbers that illustrate the relationship between the area as well as the nerve which supplies that area. For instance, the C1 spinal nerve does not possess a dermatome, however the other spinal nerves are labeled as C1-C8 and T9 is a reference with the belly button. Dermatomes are layered in vertically on the trunk those that are located on the extremities are generally longitudinal.

Dermatome Map

The dermatome map is a common feature of textbooks that cover anatomy. The dermatome map is not consistent both within and inter-textbook. Its name isn’t consistent and some textbooks include different maps on different pages. This is particularly problematic in the event that the authors of various chapters disagree on the choice of dermatome map. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett but do not include adequate references. Furthermore, four textbooks make use of maps that do not have citations, such as one that uses only secondary sources.

Dermatomes are the areas of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly found, but they tend to be more inferior than horizontally. This is a natural variation and certain tissue types are covered with more than one. Additionally, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons of the dorsal limbs.
