2 Dermatomes Infamedic – If you’ve ever thought about how the human dermatome map looks, you’ve come to the right place. Before we move on to this map, lets look at what a dermatome is. What are the various kinds? The most important thing is what is the reason to understand dermatomes in order to comprehend our body. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers your spinal cord. Dermatomes play a crucial role in allowing doctors to develop diagrams of the spine, which help in diagnosing. Two major maps are accepted by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are widely utilized. The trigeminal nerve and the maxillary nerve are the largest dermatomes.
Dermatomes are areas of skin which are connected to a particular nerve. When there is a spinal cord injuries, pain may be felt in a dermatome, which is connected to that nerve. Similar to the pain that is caused by shingles outbreaks can be felt on specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome, you should consult with a physician.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin supplied by one spinal nerve. The nerves transmit sensory, motor, as well as autonomic information. They form a part of the peripheral nervous system which connects the brain with the all the body. A dermatome may become affected due to a spinal cord injury. When one of these dermatomes gets injured, it is able to be easily treated using a local anesthetic.
The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate the connection between the region as well as the nerve which supplies that region. For example, the C1 spinal nerve doesn’t have a dermatome. However, others spinal nerves have been labeled as C1-C8, while T9 corresponds to belly button. Dermatomes are layered in horizontally on the trunk those on the extremities tend to be longitudinal.
Dermatome Map
The dermatome map is the most common element in textbooks teaching anatomy. However, the dermatome maps is not uniform both inside and inter-textbook. The name is not consistent, and some textbooks feature distinct maps on different pages. This is particularly problematic when the authors of multiple chapters disagree on the choice of dermatome maps. Many textbooks use the maps of Foerster, Keegan, and Garrett however, they do not provide proper references. In addition, four textbooks utilize maps with no citations, and one of them is one that cites only secondary sources.
The dermatome is the area of skin that receives sensory innervation from the dorsal roots of one spinal nerve. The dermatomes are not uniformly found, but they tend to dip more inferiorly than horizontally. This is an inherent variation and some tissues may be covered by multiple dermatomes. Also dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons that originate from the dorsal parts of the limbs.
