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 move on to this map, lets talk about what is a dermatome. What are the various types? And most importantly, what is the reason to understand dermatomes in order to comprehend how the body works. Continue reading to learn 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 cord of the spinal. Dermatomes play a crucial role in allowing doctors to create models of the cord, which help in diagnosing. Two major maps are accepted by medical specialists. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and remain frequently employed. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are areas of skin that are linked to a specific nerve. When there is a spinal cord injury, pain may be felt in a dermatome, which is innervated by that nerve. Similar to the pain that is caused by shingles outbreaks is felt by specific spinal nerves. If you experience a pain or neurological condition involving the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is provided by a single spinal nerve. These nerves carry motor, sensory and autonomic messages. They form part of the peripheral nerve system, that connects the brain to the all the body. A dermatome may suffer from a spinal lesion. If one of these is injured, it can be easily treated with local anesthetic.
Dermatomes in the thoracic region are identified using letter-number sequences that demonstrate the connection between the region along with the sensor nerve that supplies that area. For example C1’s spinal nerve doesn’t have a dematome, however those spinal nerves that are labeled C1 – C8, while T9 corresponds to the belly button. Dermatomes are layered horizontally along the trunk, those that are located on the extremities are generally in a longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks that cover anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. Its name isn’t consistent as are some textbooks that have different maps on various pages. This is particularly problematic in the event that the authors of various chapters differ in their choice of dermatome map. Many textbooks use the Maps of Foerster, Keegan, and Garrett but do not include the proper references. In addition, four textbooks utilize maps with no citations, and one of them is one that uses only secondary sources.
Dermatomes are the parts of skin that receives sensory stimulation from the dorsal root of one spinal nerve. Dermatomes aren’t evenly located, but they tend to dip lower than horizontally. This is a normal variation and some tissues may be covered by multiple dermatomes. Additionally dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons in the dorsal parts of the limbs.
