Dermatomes Development Maps TeachMeAnatomy – If you’ve ever wondered what the human dermatome’s map appears, then you’re at the right place. Before we go to the map, let’s discuss the definition of a dermatome. What are the different kinds? And, most importantly, why is it necessary to know about dermatomes in order to know more about our body. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes play a crucial role in allowing physicians to build models of the cord, which aid in the diagnosis. Two major maps are accepted by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and remain often used. The trigeminal nerve , as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are skin areas which are connected to a particular nerve. In cases of spinal cord injuries, pain may be felt in a dermatome that is connected to that nerve. The same is true for the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome area, you must 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 sensory, motor, and autonomic information. They form an element of the peripheral nerve system, which connects brain and all the body. Dermatomes can get affected because of a spinal injury. When one of these dermatomes is injured, it can be easily treated using a local anesthetic.
The dermatomes of the thoracic area are marked with letter-number combinations that show the connection between the region along with the sensor nerve that supplies that area. For example C1 spinal nerve doesn’t have a dermatome. However, the other spinal nerves are labeled C1 – C8, while T9 corresponds with the belly button. Dermatomes are laid horizontally on the trunk, and dermatomes located in the extremities are usually linear.
Dermatome Map
The dermatome map is the most common element in textbooks that teach anatomy. However, the dermatome map is not consistent both within and inter-textbook. Its name isn’t consistent and some textbooks include different maps on different pages. This is especially problematic in the event that the authors of various chapters are not unified in their choice of dermatome maps. Most textbooks use map of Foerster, Keegan, and Garrett but don’t include proper references. Moreover, four textbooks use maps without citations, including one that refers to only secondary sources.
Dermatomes are the areas of skin that receives sensory innervation from the dorsal root of one spinal nerve. Dermatomes aren’t evenly situated, but they tend to be more inferior than horizontally. This is a natural variation and some tissues have more than one. Furthermore dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons in the dorsal limbs.
