Facial Nerve Dermatomes PurposeGames – If you’ve ever wondered what the human dermatome’s map looks, you’ve come to the right place. Before we go to an image, it’s important to discuss the definition of a dermatome. What are the various kinds? Most importantly, why is it necessary to be aware of dermatomes order to better understand the human body. Read on to find out more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes play a crucial role in allowing physicians to build diagrams of the spine, which are useful for diagnosis. Two major maps are accepted by medical professionals. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are widely used. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that are linked to a specific nerve. In the case of spinal cord injury, pain may be felt in a dermatome that is innervated by 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 pain or neurological condition involving the dermatome, it is recommended that you visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin supplied by the spinal nerve. The nerves transmit sensory, motor, and autonomic signals. They form an element of the peripheral nervous system, which connects brain and rest of the body. Dermatomes can become affected due to a spinal cord injury. When one of these dermatomes gets injured, it is able to be easily treated using an local anesthetic.
The dermatomes of the thoracic region have been labeled using letter-number sequences that demonstrate the connection between the area and the sensory nerve that supplies that region. For instance, the C1 spinal nerve doesn’t have a dematome, however those spinal nerves that are labeled C1-C8, while T9 corresponds to belly button. Dermatomes are layered in horizontally on the trunk while dermatomes in the extremities are usually long.
Dermatome Map
The dermatome map is the most common element in textbooks that teach anatomy. The dermatome map is not uniform both inside and inter-textbook. The names are inconsistent and certain textbooks have various maps on different pages. This can be particularly challenging when the authors of several chapters do not agree on the selection of dermatome maps. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett however, they do not provide proper references. Furthermore, four textbooks make use of maps that do not have citations, such as one that uses only secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly located, but they tend to dip less inferiorly than horizontally. This is a normal variation and some tissues may be covered by multiple dermatomes. Additionally dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons that originate from those limbs that are dorsal.
