Dermatome Map Of Head By Annie Campbell University Of Du Flickr – If you have ever wondered how the human dermatome chart looks, you’ve come to the right place. Before we look at this map, lets discuss the definition of a dermatome. What are the different types? And most importantly, why is it necessary to understand dermatomes in order to better understand our body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.
What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the spine. Dermatomes can help doctors to create maps of the spinal cord that are useful for diagnosis. Two major maps are recognized by medical experts. The Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still commonly utilized. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that are attached to a particular nerve bundle. In cases of spinal cord injury, pain may be experienced in a dermatome that is controlled by the nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in particular spinal nerves. If you experience a neurologic condition or pain that involves the dermatome, you should consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by only one spinal nerve. These nerves provide sensory, motor, and autonomic messages. They form a part of the peripheral nerve system, which connects the brain and other parts of the body. Dermatomes can get affected because of a spinal lesion. If one of these becomes injured, it can be easily treated using a local anesthetic.
The dermatomes of the thoracic area are marked using letter-number sequences that demonstrate the connection between the region in question and the sensory nerve which supplies this area. For instance C1’s spinal nerve does not have a dematome, however the other spinal nerves are identified as C1-C8 T9, which corresponds to the belly button. Dermatomes are layered in horizontally on the trunk while dermatomes on the extremities tend to be linear.
Dermatome Map
Dermatome maps are the most common element in textbooks that cover anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. Its naming is inconsistent, and some textbooks feature different maps on different pages. This can be particularly challenging when the authors of several chapters are not unified in their choice of dermatome map. Many textbooks use the Maps of Foerster, Keegan, and Garrett but don’t include appropriate references. Moreover, four textbooks use maps with no citations, and one of them is one that refers to only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal branch of one spinal nerve. The dermatomes are not uniformly found, but they tend to dip lower than horizontally. This is a normal variation and some tissues have more than one. Also dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons that originate from the dorsal parts of the limbs.
