C2 Dermatome Map – If you’ve ever thought about what the human dermatome map will look, you’re in the right place. Before we move on to an image, it’s important to look at what a dermatome actually is. What are the different kinds? And most importantly, why is it necessary to know about dermatomes in order to better understand how the body works. 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 play a crucial role in allowing doctors to create diagrams of the spine that aid in the diagnosis. Two major maps are accepted by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are still often utilized. The trigeminal nerve and the maxillary nerve are the largest dermatomes.

Dermatomes are skin areas that connect to a specific nerve. When there is a spinal cord injury, pain may be felt in a dermatome, which is connected to that nerve. The same is true for the pain caused by shingles outbreaks can be felt in specific spinal nerves. If you experience a nerve pain or neurological problem affecting the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?

A dermatome is a segment of skin supplied by one spinal nerve. The nerves transmit motor, sensory, and autonomic information. They form a part of the peripheral nervous system which connects the brain and rest of the body. A dermatome may become affected due to a spinal injury. If one of these is injured, it can be easily treated using a local anesthetic.

Dermatomes in the thoracic region are identified with letter-number combinations that show the connection between the area in question and the sensory nerve that serves the area. For example C1’s spinal nerve does not have a dermatome, but those spinal nerves that are identified as C1-C8 and T9 is a reference to the belly button. Dermatomes are laid horizontally on the trunk, those in the extremities are usually linear.

Dermatome Map

Dermatome maps are an integral part of textbooks that cover anatomy. However, the dermatome map is inconsistency both within and inter-textbook. Its naming is inconsistent as are some textbooks that have distinct maps on different pages. This is especially problematic in the event that the authors of various chapters differ in their choice of dermatome map. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett but do not include proper references. Additionally, four textbooks employ maps with no citations, and one of them is one that uses only secondary sources.

Dermatomes are the parts of skin that receives sensory input from the dorsal roots of one spinal nerve. The dermatomes are not uniformly located, but they tend to dip less inferiorly than horizontally. This is a normal variation and certain tissues are covered by more than one dermatome. Additionally dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons from the dorsal limbs.
