Printable Dermatome Map Printable Maps – If you’ve ever wondered what the human dermatome’s map will look, you’re in the right spot. Before we go to our map, we’ll discuss the definition of a dermatome. What are the various kinds? Most importantly, why is it important to understand dermatomes in order to know more about the human body. Read on to find out more. You might be surprised! Here are some examples of dermatomes.
What is a Dermatome?
The term “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes are important in allowing physicians to build images of spinal cord, which aid in the diagnosis. Two maps are widely accepted by medical experts. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are commonly employed. The trigeminal nerve , as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are skin regions which are connected to a specific nerve. In cases of spinal cord injury, pain can be felt in a dermatome, which is surrounded by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you experience a pain or neurological condition involving the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is provided by only one spinal nerve. The nerves transmit motor, sensory, and autonomic messages. They form an element of the peripheral nerve system, which connects the brain with the other parts of the body. A dermatome may get affected because of a spinal injury. If one of these gets injured, it is able to be easily treated using a local anesthetic.
Dermatomes in the thoracic region have been labeled with letter-number combinations that show how the region is connected as well as the nerve which supplies the area. For example C1’s spinal nerve does not possess a dermatome, however those spinal nerves that are labeled as C1-C8 T9, which corresponds with the belly button. Dermatomes are layered in vertically on the trunk those that are located on the extremities are generally longitudinal.
Dermatome Map
Dermatome maps are an integral part of textbooks that teach anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. The names are inconsistent as are some textbooks that have different maps on various pages. This is particularly problematic when the authors of different chapters do not agree on the selection of dermatome map. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett however, they do not provide the proper references. In addition, four textbooks utilize maps that do not have citations, such as one that refers to only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal branch of one spinal nerve. The dermatomes are not uniformly found, but they tend to dip more inferiorly than horizontally. This is a normal variation and some tissues have more than one. Also dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal parts of the limbs.
