Dermatomes And Myotomes Sensation Anatomy Geeky Medics – If you’ve ever wondered what the human dermatome map appears, then you’re at the right spot. Before we look at this map, lets talk about what a dermatome actually is. What are the various types? Most importantly, why is it necessary to know about dermatomes in order to understand how the body works. Read on to find out more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help doctors to develop maps of the spinal cord, which can be useful in diagnosing. Two maps are widely accepted by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are often used. 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 particular nerve bundle. In cases of spinal injury, pain can be experienced in a dermatome that is controlled by the nerve. Similarly, the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you suffer from discomfort or neurological issue involving the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by one spinal nerve. These nerves provide motor, sensory, and autonomic signals. They form part of the peripheral nervous system which connects the brain with the all the body. Dermatomes can become affected due to a spinal lesion. If one of these dermatomes becomes injured, it could be treated easily with the use of a local anesthetic.
The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate the relationship between the area in question and the sensory nerve that serves this area. For instance C1’s spinal nerve does not have a dermatome. However, the other spinal nerves are labeled C1-C8, while T9 corresponds to the belly button. Dermatomes are laid horizontally along the trunk, and dermatomes located on the extremities tend to be linear.
Dermatome Map
Dermatome maps are one of the common features of textbooks that teach anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. The names are inconsistent and some textbooks include various maps on different pages. This is especially problematic when the authors of several chapters disagree on the choice of dermatome maps. Many textbooks use the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide proper references. Moreover, four textbooks use maps that do not have citations, such as one that cites only secondary sources.
Dermatomes are the areas of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly situated, but they tend to dip more inferiorly than horizontally. This is a natural variation, and some tissues have more than one. Additionally, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons from those limbs that are dorsal.
