Dermatome Map Of The Upper Limb Stock Photo Alamy – If you have ever wondered what the human dermatome map appears, then you’re at the right place. Before we look at this map, lets take a look at what a dermatome actually is. What are the various kinds? The most important thing is why is it essential to know about dermatomes in order to understand our body. 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 your spinal cord. Dermatomes are important in allowing physicians to build images of spinal cord that are useful for diagnosis. Two maps are widely accepted by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain widely utilized. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that are attached to a specific nerve bundle. In cases of spinal injury, pain can be felt in a dermatome which is controlled by the nerve. The same is true for the pain caused by shingles outbreaks is felt by specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is provided by the spinal nerve. These nerves relay sensory, motor and autonomic messages. They form an element of the peripheral nerve system which connects the brain and other parts of the body. A dermatome may be affected by a spinal cord injury. If one of these dermatomes gets injured, it is able to be easily treated with local anesthetic.
The dermatomes of the thoracic region have been labeled with letter-number combinations that show the relationship between the area in question and the sensory nerve which supplies that region. For example, the C1 spinal nerve does not have a dematome, however those spinal nerves that are labeled C1 – C8 and T9 refers to the belly button. Dermatomes are layered in horizontally on the trunk, those on the extremities are typically long.
Dermatome Map
Dermatome maps are an integral part of textbooks teaching anatomy. But, the map is inconsistent both intra and inter-textbook. The names are inconsistent and some textbooks include different maps on various pages. This is particularly problematic when the authors of different chapters differ in their choice of dermatome map. The majority of textbooks utilize 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 parts of skin that receives sensory input from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip lower than horizontally. This is a natural variation, and certain tissues have more than one. Furthermore dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons that originate from the dorsal limbs.
