Dermatome Distribution For The Cervical Spine Netter Muscle Anatomy – If you’ve ever wondered what the human dermatome map is, you’ve come to the right place. Before we go to an image, it’s important to discuss what is a dermatome. What are the different types? And most importantly, why is it important to learn about dermatomes in order to understand how the body works. Read on to find out more. You may be surprised! Here are some examples of dermatomes.
What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers the spine. Dermatomes play a crucial role in allowing doctors to create diagrams of the spine, which aid in the diagnosis. Two maps are widely accepted by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are widely used. The trigeminal nerve as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are areas of skin that are attached to a particular nerve. In cases of spinal cord injury, the pain could be experienced in a dermatome that is surrounded by the nerve. In the same way, the pain triggered by shingles outbreaks can be felt in specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is provided by one spinal nerve. These nerves carry sensory, motor and autonomic messages. They form a part of the peripheral nerve system, which connects the brain with the all the body. A dermatome may become affected due to a spinal cord injury. When one of these dermatomes becomes injured, it can be easily treated using a local anesthetic.
The dermatomes of the thoracic region have been labeled by letter-number combinations, which show the connection between the region and the sensory nerve that supplies the area. For example the C1 spinal nerve does not possess a dermatome, however the other spinal nerves are labeled C1-C8 and T9 refers to belly button. Dermatomes are laid vertically on the trunk those in the extremities are usually long.
Dermatome Map
The dermatome map is the most common element in textbooks that cover anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. Its name isn’t consistent and some textbooks include different maps on different pages. This can be particularly challenging when the authors of different chapters do not agree on the selection of dermatome map. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide proper references. Additionally, four textbooks employ maps with no citations, and one of them is one that uses only secondary sources.
Dermatomes are the areas of the skin that receives sensory information 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 an inherent variation and certain tissues are covered by more than one dermatome. Additionally dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons of the dorsal parts of the limbs.
