Pin On DERMATOMES – If you’ve ever wondered what the human dermatome’s map will look, you’re in the right place. Before we go to the map, let’s look at what a dermatome actually is. What are the various types? The most important thing is why is it essential to be aware of dermatomes order to know more about the human body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers the spinal cord. Dermatomes help doctors to construct maps of the spinal cord that are useful for diagnosis. Two major maps are accepted by medical specialists. The Keegan and Garret map and the Foerster map. These maps were created in the 1930s, and are commonly used. The trigeminal and maxillary nerve are the biggest dermatomes.
Dermatomes are skin areas that are attached to a specific nerve. When there is a spinal cord injury, pain can be felt in a dermatome, which is surrounded by the nerve. In the same way, the pain triggered by an outbreak of shingles is felt by specific spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by a single spinal nerve. These nerves provide sensory, motor, and autonomic messages. They form part of the peripheral nervous system, which connects brain and other parts of the body. Dermatomes can become affected due to a spinal cord lesion. When one of these dermatomes becomes injured, it can be easily treated with the use of a local anesthetic.
The dermatomes of the thoracic area are marked with letters-numbers that illustrate the relationship between the area and the sensory nerve which supplies the area. For example, the C1 spinal nerve does not possess a dermatome, however the other spinal nerves are labeled C1 – C8 T9, which corresponds to belly button. Dermatomes are laid horizontally on the trunk and dermatomes located that are located on the extremities are generally in a longitudinal.
Dermatome Map
Dermatome maps are the most common element in textbooks teaching anatomy. The dermatome map is inconsistency both within and inter-textbook. The name is not consistent and some textbooks include different maps on different pages. This is particularly problematic in the event that the authors of various chapters differ in their choice of dermatome map. Most textbooks use Maps of Foerster, Keegan, and Garrett but don’t include the proper references. Additionally, four textbooks employ maps that do not have citations, such as one that refers to only secondary sources.
Dermatomes are the regions of the skin that receives sensory information from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly placed, however they tend to be more inferior than horizontally. This is a natural variation, and some tissues are covered by more than one dermatome. Additionally dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal parts of the limbs.
