Abdominal Dermatome Map – If you’ve ever thought about how the human dermatome chart is, you’ve come to the right place. Before we move on to the map, let’s look at what is a dermatome. What are the various types? The most important thing is why is it important to be aware of dermatomes order to know more about how the body works. 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 spine. Dermatomes can help doctors to create models of the cord, which aid in the diagnosis. Two major maps are accepted by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain commonly employed. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.

Dermatomes are skin areas which are connected to a specific nerve bundle. In the case of spinal cord injury, the pain could be experienced in a dermatome that is innervated by that nerve. In the same way, the pain triggered by shingles outbreaks is felt by specific spinal nerves. If you are experiencing pain or neurological condition involving the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?

A dermatome is a segment of skin that is provided by only one spinal nerve. These nerves carry motor, sensory, and autonomic messages. They form part of the peripheral nervous system, that connects the brain to the rest of the body. A dermatome may suffer from a spinal cord injury. If one of these dermatomes becomes injured, it could be easily treated with the use of a local anesthetic.

The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate the relationship between the area and the sensory nerve which supplies the area. For example, the C1 spinal nerve doesn’t have a dermatome, but those spinal nerves that are identified as C1-C8, while T9 corresponds to belly button. Dermatomes are layered vertically on the trunk while dermatomes on the extremities tend to be long.

Dermatome Map

Dermatome maps are an integral part of textbooks teaching anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. The names are inconsistent and certain textbooks have distinct maps on different pages. This can be particularly challenging when the authors of different chapters disagree on the choice of dermatome map. Many textbooks use the map of Foerster, Keegan, and Garrett however, they do not provide appropriate references. Moreover, four textbooks use maps without citations, including one that only cites secondary sources.

Dermatomes are the regions of skin that receives sensory innervation from the dorsal root of one spinal nerve. The dermatomes are not uniformly located, but they tend to be more inferior than horizontally. This is a natural variation, and certain tissues are covered by more than one dermatome. Also dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons of Dorsal limbs.
