Paediatric Neurological Examination OSCE Guide Geeky Medics – If you have ever wondered how the human dermatome map appears, then you’re at the right spot. Before we look at this map, lets discuss what is a dermatome. What are the different types? And, most importantly, why is it essential to be aware of dermatomes order to comprehend our body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes help doctors to construct maps of the spinal cord that help in diagnosing. Two major maps are recognized by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain often used. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that connect to a specific nerve. In cases of spinal injury, pain may be felt in a dermatome, which 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 discomfort or neurological issue involving the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by a single spinal nerve. The nerves transmit motor, sensory, and autonomic information. They form part of the peripheral nerve system which connects the brain with the rest of the body. Dermatomes can suffer from a spinal cord injury. If one of these gets injured, it is able to be easily treated using local anesthetic.
Dermatomes in the thoracic region are labeled with letters-numbers that illustrate how the region is connected as well as the nerve that is responsible for the area. For instance C1 spinal nerve doesn’t have a dermatome. However, the other spinal nerves are identified as C1-C8 T9, which corresponds with the belly button. Dermatomes are layered horizontally on the trunk, and dermatomes located that are located on the extremities are generally in a longitudinal.
Dermatome Map
The dermatome map is the most common element in textbooks that teach anatomy. The dermatome map is not uniform both inside and inter-textbook. The names are inconsistent as are some textbooks that have distinct maps on different pages. This is especially problematic when the authors of multiple chapters are not unified in their choice of dermatome map. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide the proper references. In addition, four textbooks utilize maps that do not have citations, such as one that cites only secondary sources.
Dermatomes are the areas of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly placed, however they tend to dip more inferiorly than horizontally. This is a normal variation and certain tissues have more than one. Also dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons from the dorsal parts of the limbs.
