Anterior UE Dermatomes Quiz – If you have ever wondered how the human dermatome chart will look, you’re in the right place. Before we go to this map, lets discuss the definition of a dermatome. What are the different types? Most importantly, what is the reason to learn about dermatomes in order to understand the human 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 can help doctors to develop images of spinal cord, which are useful for diagnosis. Two major maps are regarded as valid by medical professionals. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain widely used. The trigeminal and maxillary nerve are the biggest dermatomes.
Dermatomes are areas of skin which are connected to a particular nerve bundle. In cases of spinal cord injury, the pain could be felt in a dermatome which is surrounded by the 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, you should consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by a single spinal nerve. These nerves carry sensory, motor, and autonomic signals. They form an element of the peripheral nervous system which connects brain and other parts of the body. Dermatomes can become affected due to a spinal cord lesion. If one of these becomes injured, it can be easily treated with an local anesthetic.
Dermatomes in the thoracic region are labeled by letter-number combinations, which show how the region is connected as well as the nerve which supplies that area. For instance C1’s spinal nerve doesn’t have a dermatome. However, others spinal nerves have been identified as C1-C8 and T9 refers to belly button. Dermatomes are layered in horizontally on the trunk however, dermatomes on the extremities are typically linear.
Dermatome Map
Dermatome maps are one of the common features of textbooks teaching anatomy. However, the dermatome map is not consistent both within and inter-textbook. The name is not consistent as are some textbooks that have various maps on different pages. This is especially problematic in the event that the authors of various chapters disagree on the choice of dermatome maps. Most textbooks use Maps of Foerster, Keegan, and Garrett however they don’t provide the proper references. In addition, four textbooks utilize maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal roots of one spinal nerve. The dermatomes are not uniformly located, but they tend to dip lower than horizontally. This is an inherent variation and some tissues are covered by more than one dermatome. Also, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons from the dorsal limbs.
