Dermatomes What Are They Dr Michael A Castillo MD – If you’ve ever thought about what the human dermatome’s map will look, you’re in the right spot. Before we get to the map, let’s discuss what is a dermatome. What are the different kinds? Most importantly, what is the reason to understand dermatomes in order to understand your body. Read on to find out more. You may be surprised! Here are some examples of dermatomes.
What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes play a crucial role in allowing doctors to develop models of the cord that aid in the diagnosis. Two major maps are recognized by medical specialists. They are 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 skin areas which are connected to a specific nerve bundle. In cases of spinal injury, the pain could be felt in a dermatome which is connected to that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in specific spinal nerves. If you experience a neurologic condition or pain that involves the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is provided by one spinal nerve. These nerves relay motor, sensory and autonomic information. They form a part of the peripheral nervous system that connects the brain to the rest of the body. Dermatomes can get affected because of a spinal cord injury. When one of these dermatomes gets injured, it is able to be easily treated using a local anesthetic.
Dermatomes in the thoracic region are identified with letters-numbers that illustrate the connection between the area along with the sensor nerve that supplies the area. For example, the C1 spinal nerve doesn’t have a dermatome. However, those spinal nerves that are labeled as C1-C8 and T9 is a reference with the belly button. Dermatomes are layered in horizontally on the trunk however, dermatomes in the extremities are usually in a longitudinal.
Dermatome Map
The dermatome map is one of the common features of textbooks that teach anatomy. The dermatome map is not consistent both within and inter-textbook. The names are inconsistent and certain textbooks have distinct maps on different pages. This is particularly problematic when the authors of multiple chapters differ in their choice of dermatome map. A majority of textbooks employ the Maps of Foerster, Keegan, and Garrett but do not include proper references. Furthermore, four textbooks make use of maps without citations, including one that refers to only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t evenly located, but they tend to be more inferior than horizontally. This is an inherent variation and some tissue types are covered with more than one. Furthermore, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons in the dorsal limbs.
