Dermatome And Myotome Map – If you have ever wondered how the human dermatome map appears, then you’re at the right spot. Before we move on to the map, let’s talk about the definition of a dermatome. What are the different types? Most importantly, why is it necessary to learn about dermatomes in order to understand the human body. Read on to find out 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 covers the cord of the spinal. Dermatomes can help doctors to create maps of the spinal cord that help in diagnosing. Two maps are widely accepted by medical professionals. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are commonly used. The trigeminal and maxillary nerve are the biggest dermatomes.

Dermatomes are skin areas that are linked to a particular nerve. In the case of spinal cord injury, pain may be felt in a dermatome that is connected to that nerve. Similar to the pain that is caused by shingles outbreaks can be felt in specific spinal nerves. If you experience a pain or neurological condition involving the dermatome, you should consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is provided by a single spinal nerve. These nerves relay sensory, motor as well as autonomic information. They form part of the peripheral nervous system which connects brain and other parts of the body. Dermatomes can suffer from a spinal lesion. If one of these becomes injured, it could be treated easily with an local anesthetic.

The dermatomes of the thoracic region have been labeled by letter-number combinations, which show the relationship between the area in question and the sensory nerve that supplies that region. For example, the C1 spinal nerve doesn’t have a dermatome. However, the other spinal nerves are labeled as C1-C8, while T9 corresponds with the belly button. Dermatomes are layered horizontally on the trunk, while dermatomes in the extremities are usually in a longitudinal.

Dermatome Map

Dermatome maps are one of the common features of textbooks that cover anatomy. But, the map is not consistent both within and inter-textbook. The names are inconsistent as are some textbooks that have different maps on various pages. This is particularly problematic when the authors of multiple chapters do not agree on the selection of dermatome maps. Many textbooks use the Maps of Foerster, Keegan, and Garrett but don’t include adequate references. In addition, four textbooks utilize maps without citations, including one that refers to only secondary sources.

Dermatomes are the parts of skin that receives sensory innervation from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly situated, but they tend to dip lower than horizontally. This is an inherent variation and certain tissues are covered by more than one dermatome. Additionally dorsal spinal rootlets could have intrathecal intersegmental anastomoses with sensory neurons that originate from the dorsal parts of the limbs.
