Cervical Dermatome Map Physical Therapy Massage Therapy Hand Therapy – If you’ve ever wanted to know what the human dermatome’s map looks, you’ve come to the right spot. Before we look at this map, lets take a look at what a dermatome actually is. What are the various kinds? Most importantly, why is it essential to learn about dermatomes in order to know more about how the body works. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes play a crucial role in allowing doctors to develop maps of the spinal cord, which are useful for diagnosis. 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 often employed. The trigeminal nerve and the maxillary nerve are the largest 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. The same is true for the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you experience a pain or neurological condition involving the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by only one spinal nerve. These nerves provide sensory, motor, and autonomic messages. They form part of the peripheral nerve system, which connects brain and rest of the body. Dermatomes can be affected by a spinal injury. If one of these dermatomes becomes injured, it could be easily treated with an local anesthetic.
Dermatomes in the thoracic region are labeled by letter-number combinations, which show how the region is connected and the sensory nerve that supplies the area. For instance, the C1 spinal nerve doesn’t have a dermatome, but the other spinal nerves are identified as C1-C8, while T9 corresponds with the belly button. Dermatomes are laid horizontally on the trunk however, dermatomes on the extremities tend to be in a longitudinal.
Dermatome Map
The dermatome map is an integral part of textbooks teaching anatomy. But, the map is not uniform both inside and inter-textbook. Its naming is inconsistent and some textbooks include 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. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide appropriate references. Additionally, four textbooks employ maps without citations, including one that only cites secondary sources.
Dermatomes are the areas of skin that receives sensory stimulation from the dorsal root of a spinal nerve. The dermatomes are not uniformly located, but they tend to dip less inferiorly than horizontally. This is a natural variation and certain tissues may be covered by multiple dermatomes. Additionally dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons that originate from those limbs that are dorsal.
