Dermatomes What Are They Dr Michael A Castillo MD – If you have ever wondered how the human dermatome chart looks, you’ve come to the right place. Before we move on to our map, we’ll take a look at what is a dermatome. What are the various types? And, most importantly, why is it necessary to be aware of dermatomes order to comprehend our body. Read on to find out more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers the spine. Dermatomes play a crucial role in allowing doctors to construct maps of the spinal cord, which can be useful in diagnosing. Two major maps are recognized by medical experts. These are: the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s, and are often employed. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that connect to a specific nerve. In the case of spinal cord injuries, pain may be felt in a dermatome, which is innervated by that nerve. Similarly, the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you experience a nerve pain or neurological problem affecting the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by the spinal nerve. The nerves transmit sensory, motor and autonomic signals. They form a part of the peripheral nervous system, which connects the brain and other parts of the body. Dermatomes can get affected because of a spinal cord injury. If one of these dermatomes is injured, it can be easily treated using an local anesthetic.
Dermatomes in the thoracic region are identified with letters-numbers that illustrate the connection between the region along with the sensor nerve which supplies this area. For instance C1 spinal nerve doesn’t have a dematome, however the other spinal nerves are labeled C1 – C8, while T9 corresponds with the belly button. Dermatomes are laid horizontally on the trunk, however, dermatomes on the extremities tend to be longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks that cover anatomy. The dermatome map is inconsistent both intra and inter-textbook. The name is not consistent, and some textbooks feature various maps on different pages. This is especially problematic when the authors of several chapters are not unified in their choice of dermatome maps. A majority of textbooks employ the map of Foerster, Keegan, and Garrett however, they do not provide appropriate references. Additionally, four textbooks employ maps with no citations, and one of them is one that cites only secondary sources.
The dermatome is the area of the skin that receives sensory information from the dorsal branch of one spinal nerve. The dermatomes are not uniformly located, but they tend to dip more inferiorly than horizontally. This is a natural variation and certain tissues are covered by more than one dermatome. Furthermore dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons from those limbs that are dorsal.
