Dermatomes Neurology Medbullets Step 1 – If you’ve ever wondered how the human dermatome map will look, you’re in the right place. Before we move on to this map, lets look at what a dermatome actually is. What are the various types? And, most importantly, what is the reason to learn about dermatomes in order to understand how the body works. 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 covers your spinal cord. Dermatomes play a crucial role in allowing physicians to build diagrams of the spine, which aid in the diagnosis. Two maps are widely accepted by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain commonly employed. The trigeminal nerve and the maxillary nerve are the largest dermatomes.
Dermatomes are skin regions that are linked to a specific nerve bundle. In the case of spinal cord injury, pain may be experienced in a dermatome that is connected to that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt on specific spinal nerves. If you are experiencing pain or neurological condition involving the dermatome region, you need to consult a physician.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is supplied by only one spinal nerve. The nerves transmit motor, sensory as well as autonomic information. They form part of the peripheral nervous system, which connects brain and all the body. A dermatome may be affected by a spinal injury. If one of these is injured, it can be easily treated using a local anesthetic.
Dermatomes in the thoracic region have been labeled by letter-number combinations, which show the connection between the area and the sensory nerve which supplies that region. For instance C1’s spinal nerve doesn’t have a dematome, however the other spinal nerves are labeled as C1-C8, while T9 corresponds to belly button. Dermatomes are laid vertically on the trunk however, dermatomes on the extremities are typically long.
Dermatome Map
The dermatome map is the most common element in textbooks that teach anatomy. The dermatome map is not uniform both inside and inter-textbook. Its name isn’t consistent and certain textbooks have different maps on various pages. This is especially problematic in the event that the authors of various chapters do not agree on the selection of dermatome maps. Most textbooks use maps of Foerster, Keegan, and Garrett however, they do not provide appropriate references. Moreover, four textbooks use maps without citations, including one that cites only secondary sources.
The dermatome is the area of skin that receives sensory innervation from the dorsal branch of one spinal nerve. The dermatomes are not uniformly situated, but they tend to dip less inferiorly than horizontally. This is a normal variation and some tissues may be covered by multiple dermatomes. Additionally dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons from the dorsal parts of the limbs.
