Dermatomes Nclex Radiculopathy Occupational Therapy Spinal Nerve – If you’ve ever thought about what the human dermatome map looks, you’ve come to the right spot. Before we get to an image, it’s important to discuss the definition of a dermatome. What are the different types? And most importantly, why is it essential to know about dermatomes in order to better understand how the body works. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes play a crucial role in allowing doctors to construct images of spinal cord that 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 are often utilized. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that are attached to a specific nerve. In cases of spinal injuries, pain may be felt in a dermatome that is surrounded by the nerve. Similarly, the pain caused by shingles outbreaks is felt by specific spinal nerves. If you are experiencing nerve pain or neurological problem affecting the dermatome region, you need to consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is provided by only one spinal nerve. These nerves carry motor, sensory and autonomic messages. They form part of the peripheral nervous system, which connects the brain with the all the body. Dermatomes can become affected due to a spinal cord injury. If one of these dermatomes gets injured, it is able to be easily treated using the use of a local anesthetic.
The dermatomes of the thoracic region are identified with letter-number combinations that show the connection between the area in question and the sensory nerve that is responsible for that area. For example the C1 spinal nerve does not have a dematome, however others spinal nerves have been labeled C1-C8 and T9 is a reference with the belly button. Dermatomes are laid horizontally on the trunk, those on the extremities are typically linear.
Dermatome Map
The dermatome map is the most common element in textbooks teaching anatomy. However, the dermatome map is inconsistency both within and inter-textbook. The names are inconsistent as are some textbooks that have various maps on different pages. This is particularly problematic when the authors of multiple chapters do not agree on the selection of dermatome maps. Most textbooks use diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide proper references. Moreover, four textbooks use maps with no citations. This includes one that only cites secondary sources.
Dermatomes are the regions of skin that receives sensory input from the dorsal branch of one spinal nerve. The dermatomes are not uniformly located, but they tend to dip lower than horizontally. This is an inherent variation and certain tissues may be covered by multiple dermatomes. Furthermore, dorsal spinal rootlets may contain intrathecal intersegmental connections with sensory neurons that originate from the dorsal limbs.
