Paediatric Neurological Examination OSCE Guide Geeky Medics – If you’ve ever thought about how the human dermatome map looks, you’ve come to the right place. Before we move on to the map, let’s discuss what a dermatome actually is. What are the different kinds? And most importantly, why is it essential to learn about dermatomes in order to understand the human body. Read on to find out more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the spine. Dermatomes can help physicians to build diagrams of the spine, which are useful for diagnosis. Two major maps are accepted by medical experts. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s, and are often utilized. The trigeminal and maxillary nerve are the largest dermatomes.
Dermatomes are skin regions that connect to a specific nerve. In the case of spinal cord injury, pain may be experienced in a dermatome that is controlled by the nerve. In the same way, the pain triggered by shingles outbreaks can be felt in specific spinal nerves. If you experience a nerve pain or neurological problem affecting the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by the spinal nerve. The nerves transmit motor, sensory and autonomic information. They form an element of the peripheral nerve system, which connects brain and other parts of the body. Dermatomes can become affected due to a spinal cord injury. If one of these gets injured, it is able to be treated easily with a local anesthetic.
The dermatomes of the thoracic area are marked by letter-number combinations, which show the relationship between the area and the sensory nerve that is responsible for that area. For example C1 spinal nerve doesn’t have a dermatome, but those spinal nerves that are identified as C1-C8 and T9 refers to the belly button. Dermatomes are laid horizontally on the trunk and dermatomes located in the extremities are usually in a longitudinal.
Dermatome Map
The dermatome map is the most common element in textbooks that teach anatomy. However, the dermatome maps is not uniform both inside and inter-textbook. Its name isn’t consistent and certain textbooks have distinct maps on different pages. This can be particularly challenging when the authors of several chapters do not agree on the selection of dermatome maps. The majority of textbooks utilize the map of Foerster, Keegan, and Garrett however they don’t provide appropriate references. Furthermore, four textbooks make use of maps that do not have citations, such as one that uses only secondary sources.
Dermatomes are the areas of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly placed, however they tend to dip lower than horizontally. This is a normal variation and some tissue types are covered with more than one. Additionally dorsal spinal rootlets could have intrathecal intersegmental anastomoses with sensory neurons that originate from the dorsal limbs.
