C For Chocolate 2011 – If you have ever wondered how the human dermatome chart will look, you’re in the right place. Before we get to the map, let’s take a look at the definition of a dermatome. What are the different types? Most importantly, why is it essential to understand dermatomes in order to better 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?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes are important in allowing physicians to build diagrams of the spine, which aid in the diagnosis. Two maps are widely accepted by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are commonly used. The trigeminal nerve , as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are areas of skin that are attached to a specific nerve. In cases of spinal injury, the pain could be felt in a dermatome which is innervated by that nerve. Similarly, the pain caused by an outbreak of shingles can be felt on 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?
A dermatome is a segment of skin supplied by a single spinal nerve. These nerves provide sensory, motor and autonomic signals. They form a part of the peripheral nerve system that connects the brain to the all the body. Dermatomes can be affected by a spinal injury. When one of these dermatomes gets injured, it is able to be treated easily with a local anesthetic.
The dermatomes of the thoracic region are identified with letters-numbers that illustrate the connection between the area in question and the sensory nerve that supplies the area. For instance, the C1 spinal nerve doesn’t possess a dermatome, however the other spinal nerves are labeled as C1-C8 T9, which corresponds to the belly button. Dermatomes are layered vertically on the trunk however, dermatomes that are located on the extremities are generally linear.
Dermatome Map
Dermatome maps are the most common element in textbooks teaching anatomy. The dermatome map is not consistent both within and inter-textbook. The name is not consistent, and some textbooks feature different maps on various pages. This is particularly problematic when the authors of several chapters do not agree on the selection of dermatome map. Many textbooks use the maps of Foerster, Keegan, and Garrett however they don’t provide proper references. Additionally, four textbooks employ maps without citations, including one that uses only secondary sources.
The dermatome is the area of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t evenly located, but they tend to dip lower than horizontally. This is an inherent variation and some tissues are covered by more than one dermatome. Also dorsal spinal roots could have intrathecal intersegmental anastomoses with sensory neurons of the dorsal parts of the limbs.
