Paediatric Neurological Examination OSCE Guide Geeky Medics – If you’ve ever wondered how the human dermatome chart looks, you’ve come to the right place. Before we get to an image, it’s important to look at what a dermatome actually is. What are the different kinds? And most importantly, what is the reason to learn about dermatomes in order to comprehend our body. Read on to find out more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers the spine. Dermatomes are important in allowing doctors to create diagrams of the spine that are useful for diagnosis. Two major maps are accepted by medical professionals. They are the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still often employed. The trigeminal nerve and the maxillary nerve are the largest dermatomes.
Dermatomes are skin areas that are attached to a specific nerve bundle. When there is a spinal cord injury, pain can 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 neurologic condition or pain that involves the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is provided by one spinal nerve. These nerves provide sensory, motor and autonomic information. They form part of the peripheral nerve system, which connects brain and other parts of the body. Dermatomes can get affected because of a spinal cord lesion. If one of these becomes injured, it can be treated easily with local anesthetic.
Dermatomes in the thoracic region are identified with letters-numbers that illustrate the connection between the region as well as the nerve which supplies that area. For instance C1’s spinal nerve does not have a dermatome. However, the other spinal nerves are identified as C1-C8, while T9 corresponds with the belly button. Dermatomes are laid vertically on the trunk and dermatomes located in the extremities are usually long.
Dermatome Map
Dermatome maps are the most common element in textbooks that cover anatomy. But, the map is not consistent both within and inter-textbook. Its name isn’t consistent as are some textbooks that have different maps on various pages. This is especially problematic when the authors of different chapters disagree on the choice of dermatome map. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide proper references. Additionally, four textbooks employ maps that do not have citations, such as one that refers to only secondary sources.
Dermatomes are the parts of skin that receives sensory stimulation from the dorsal branch of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip lower than horizontally. This is a natural variation, and some tissues have more than one. Additionally dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons from the dorsal parts of the limbs.
