Major Dermatomes And Cutaneous Nerves Anterior And GrepMed – If you have ever wondered how the human dermatome map looks, you’ve come to the right spot. Before we look at the map, let’s take a look at the definition of a dermatome. What are the various types? And most importantly, what is the reason to understand dermatomes in order to know more about the human body. Read on to find out more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers your spinal cord. Dermatomes help doctors to construct diagrams of the spine that are useful for diagnosis. Two maps are widely accepted by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s, and are often employed. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas which are connected to a specific nerve. In the case of spinal cord injury, pain can be felt 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 area, you must see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by only one spinal nerve. These nerves provide sensory, motor as well as autonomic information. They form an element of the peripheral nervous system, that connects the brain to the all the body. A dermatome may get affected because of a spinal cord lesion. If one of these is injured, it can be treated easily with the use of a local anesthetic.
Dermatomes in the thoracic area are marked using letter-number sequences that demonstrate how the region is connected as well as the nerve that serves that region. For instance the C1 spinal nerve doesn’t have a dermatome, but all spinal nerves in the region are labeled C1 – C8 and T9 refers with the belly button. Dermatomes are layered in horizontally along the trunk, however, dermatomes on the extremities tend to be linear.
Dermatome Map
Dermatome maps are an integral part of textbooks that cover anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. Its naming is inconsistent and certain textbooks have various maps on different pages. This can be particularly challenging when the authors of different chapters are not unified in their choice of dermatome map. Many textbooks use the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide the proper references. Additionally, four textbooks employ maps without citations, including 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 evenly placed, however they tend to dip more inferiorly than horizontally. This is an inherent variation and some tissues are covered by more than one dermatome. Additionally dorsal spinal rootlets could have intrathecal intersegmental anastomoses with sensory neurons in the dorsal limbs.
