Pin On DERMATOMES – If you have ever wondered how the human dermatome chart is, you’ve come to the right spot. Before we go to the map, let’s look at what is a dermatome. What are the different types? And, most importantly, what is the reason to understand dermatomes in order to understand our body. 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 covers the spine. Dermatomes are important in allowing physicians to build diagrams of the spine that can be useful in diagnosing. Two major maps are recognized by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still widely used. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.
Dermatomes are skin regions which are connected to a particular nerve. In cases of spinal cord injuries, pain may be felt in a dermatome which is connected to that nerve. Similar to the pain that is caused by shingles outbreaks can be felt on specific spinal nerves. If you are experiencing pain or neurological condition involving the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by a single spinal nerve. These nerves carry sensory, motor and autonomic signals. They form part of the peripheral nervous system, that connects the brain to the all the body. Dermatomes can become affected due to a spinal cord injury. If one of these becomes injured, it could be treated easily with the use of a local anesthetic.
The dermatomes of the thoracic region are identified by letter-number combinations, which show how the region is connected and the sensory nerve which supplies this area. For instance C1 spinal nerve doesn’t possess a dermatome, however the other spinal nerves are identified as C1-C8 and T9 is a reference to belly button. Dermatomes are layered horizontally on the trunk, those that are located on the extremities are generally linear.
Dermatome Map
Dermatome maps are one of the common features of textbooks that teach anatomy. The dermatome map is not uniform both inside and inter-textbook. The names are inconsistent and certain textbooks have different maps on various pages. This is especially problematic in the event that the authors of various chapters differ in their choice of dermatome maps. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett but don’t include adequate references. Additionally, four textbooks employ maps with no citations, and one of them is one that only cites secondary sources.
Dermatomes are the areas of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip less inferiorly than horizontally. This is a natural variation, and certain tissues may be covered by multiple dermatomes. In addition to this dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons from the dorsal limbs.
