Shingles UF Health University Of Florida Health – If you’ve ever thought about how the human dermatome map is, you’ve come to the right place. Before we go to the map, let’s look at what is a dermatome. What are the different types? And most importantly, why is it essential to learn about dermatomes in 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 your spinal cord. Dermatomes play a crucial role in allowing doctors to construct images of spinal cord that aid in the diagnosis. Two major maps are recognized by medical specialists. These are: 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 the largest dermatomes.
Dermatomes are skin areas that are attached to a specific nerve bundle. When there is a spinal cord injury, the pain could be experienced in a dermatome that is innervated by that nerve. Similarly, the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by only one spinal nerve. These nerves provide motor, sensory as well as autonomic information. They form a part of the peripheral nerve system, that connects the brain to the all the body. Dermatomes can be affected by a spinal cord injury. If one of these becomes injured, it can be easily treated using a local anesthetic.
The dermatomes of the thoracic region are labeled by letter-number combinations, which show how the region is connected in question and the sensory nerve that supplies that region. For example, the C1 spinal nerve does not have a dematome, however all spinal nerves in the region are labeled as C1-C8 and T9 is a reference to belly button. Dermatomes are laid horizontally on the trunk while dermatomes on the extremities tend to be long.
Dermatome Map
The dermatome map is the most common element in textbooks that teach anatomy. But, the map is not consistent both within and inter-textbook. Its name isn’t consistent as are some textbooks that have different maps on various pages. This can be particularly challenging when the authors of multiple chapters disagree on the choice of dermatome maps. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett but don’t include adequate references. In addition, four textbooks utilize maps with no citations. This includes one that refers to only secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip lower than horizontally. This is a natural variation and some tissues have more than one. Also dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons that originate from Dorsal limbs.
