Dermatome Map Back – If you’ve ever wanted to know how the human dermatome chart appears, then you’re at the right place. Before we get to this map, lets talk about what a dermatome is. What are the various kinds? The most important thing is what is the reason to learn about 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 spine. Dermatomes can help physicians to build images of spinal cord that can be useful in diagnosing. Two major maps are regarded as valid by medical specialists. There is 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 nerve are the largest dermatomes.

Dermatomes are areas of skin that are attached to a specific nerve. In cases of spinal injuries, pain may be felt in a dermatome, which is surrounded by the nerve. Similarly, the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin supplied by a single spinal nerve. These nerves provide sensory, motor and autonomic signals. They form a part of the peripheral nervous system which connects brain and other parts of the body. Dermatomes can become affected due to a spinal cord injury. If one of these is injured, it can be treated easily with 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 which supplies the area. For example the C1 spinal nerve does not possess a dermatome, however the other spinal nerves are identified as C1-C8 and T9 refers to the belly button. Dermatomes are layered in horizontally on the trunk, those on the extremities tend to be long.

Dermatome Map

The dermatome map is a common feature of textbooks that teach anatomy. The dermatome map is inconsistent both intra and inter-textbook. The name is not consistent, and some textbooks feature various maps on different pages. This is particularly problematic in the event that the authors of various chapters disagree on the choice of dermatome map. Many textbooks use the map of Foerster, Keegan, and Garrett but do not include appropriate references. Additionally, four textbooks employ maps without citations, including one that cites 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 located, but they tend to dip less inferiorly than horizontally. This is an inherent variation and certain tissues are covered by more than one dermatome. Also, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons in those limbs that are dorsal.
