Dermatomes Neurology Medbullets Step 1 – If you’ve ever thought about how the human dermatome map looks, you’ve come to the right spot. Before we go to our map, we’ll look at what is a dermatome. What are the different kinds? And most importantly, why is it necessary to understand dermatomes in order to understand your body. Read on to find out more. You might be amazed! 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 create maps of the spinal cord, which 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 developed in the 1930s and are frequently used. The trigeminal and maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas that are attached to a specific nerve bundle. When there is a spinal cord injury, pain may be felt in a dermatome, which is controlled by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt on specific spinal nerves. If you experience a nerve pain or neurological problem affecting the dermatome, it is recommended that you visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is supplied by one spinal nerve. The nerves transmit motor, sensory as well as autonomic information. They form a part of the peripheral nervous system which connects the brain and all the body. A dermatome may suffer from a spinal cord lesion. When one of these dermatomes becomes injured, it can be easily treated using an local anesthetic.
The dermatomes of the thoracic area are marked with letter-number combinations that show the connection between the region in question and the sensory nerve that serves this area. For example C1’s spinal nerve does not have a dermatome, but the other spinal nerves are labeled C1 – C8 and T9 refers with the belly button. Dermatomes are layered horizontally along the trunk, those on the extremities are typically linear.
Dermatome Map
Dermatome maps are an integral part of textbooks that teach anatomy. But, the map is not consistent both within and inter-textbook. Its naming is inconsistent 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. Most textbooks use maps of Foerster, Keegan, and Garrett however, they do not provide the proper references. Moreover, four textbooks use maps with no citations, and one of them is one that uses only secondary sources.
The dermatome is the area of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly located, but they tend to dip less inferiorly than horizontally. This is a natural variation and certain tissue types are covered with more than one. Furthermore dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons of the dorsal limbs.
