Pin On Physical Therapy – If you’ve ever thought about how the human dermatome map appears, then you’re at the right spot. Before we look at our map, we’ll discuss what a dermatome actually is. What are the different types? The most important thing is what is the reason to understand dermatomes in order to comprehend how the body works. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.
What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes are important in allowing doctors to construct maps of the spinal cord that can be useful in diagnosing. Two maps are widely accepted by medical professionals. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s, and are widely employed. The trigeminal nerve and the maxillary nerve are the largest dermatomes.
Dermatomes are skin-like areas that are attached to a particular nerve bundle. In cases of spinal cord injury, the pain could be felt in a dermatome that is controlled by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt in particular spinal nerves. If you suffer from discomfort or neurological issue involving the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by 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. A dermatome may suffer from a spinal cord injury. When one of these dermatomes is injured, it can be easily treated with an local anesthetic.
The dermatomes of the thoracic region are identified by letter-number combinations, which show the connection between the area in question and the sensory nerve that is responsible for that area. For example the C1 spinal nerve doesn’t have a dematome, however all spinal nerves in the region are labeled as C1-C8 and T9 refers with the belly button. Dermatomes are laid horizontally on the trunk while dermatomes that are located on the extremities are generally linear.
Dermatome Map
The dermatome map is one of the common features of textbooks teaching anatomy. But, the map is inconsistency both within and inter-textbook. The names are inconsistent, and some textbooks feature different maps on different pages. This is especially problematic when the authors of different chapters differ in their choice of dermatome maps. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett however they don’t provide the proper references. Additionally, four textbooks employ maps with no citations. This includes one that only cites secondary sources.
Dermatomes are the areas of skin that receives sensory innervation from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip less inferiorly than horizontally. This is a natural variation, and some tissues have more than one. Additionally dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons of those limbs that are dorsal.
