Trigeminal Dermatome Map – If you’ve ever thought about how the human dermatome chart will look, you’re in the right place. Before we get to this map, lets talk about the definition of a dermatome. What are the different types? And, most importantly, what is the reason to know about dermatomes in order to better understand our body. Continue reading to learn more. You might be surprised!

What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes can help doctors to construct images of spinal cord, which are useful for diagnosis. Two major maps are recognized by medical specialists. The Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are widely utilized. The trigeminal nerve , as well as the maxillary nerve are the biggest dermatomes.

Dermatomes are skin-like areas that are attached to a specific nerve. In cases of spinal injury, pain may be experienced in a dermatome that is connected to that nerve. In the same way, the pain triggered by an outbreak of shingles is felt by specific spinal nerves. If you feel discomfort or neurological issue involving the dermatome, it is recommended that you visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is provided by the spinal nerve. These nerves relay sensory, motor, and autonomic information. They form part of the peripheral nervous system which connects the brain and all the body. A dermatome may be affected by a spinal injury. When one of these dermatomes becomes injured, it could be easily treated using the use of a local anesthetic.

The dermatomes of the thoracic region have been labeled with letter-number combinations that show the relationship between the area and the sensory nerve that is responsible for that area. For example the C1 spinal nerve does not have a dematome, however the other spinal nerves are labeled as C1-C8 and T9 is a reference to belly button. Dermatomes are layered horizontally on the trunk and dermatomes located in the extremities are usually longitudinal.

Dermatome Map

The dermatome map is a common feature of textbooks that teach anatomy. However, the dermatome map is not uniform both inside and inter-textbook. The names are inconsistent and some textbooks include different maps on various pages. This can be particularly challenging when the authors of multiple chapters disagree on the choice of dermatome maps. Most textbooks use diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide the proper 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 the skin that receives sensory information from the dorsal branch of one spinal nerve. The dermatomes are not uniformly situated, but they tend to dip more inferiorly than horizontally. This is an inherent variation and some tissues may be covered by multiple dermatomes. In addition to this dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal parts of the limbs.
