Before we look at our map, we’ll look at what is a dermatome. What are the various types? And, most importantly, why is it essential to be aware of dermatomes order to know more about how the body works. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.
What is a Dermatome?
The term “dermatome” refers to a tissue that covers the spinal cord. Dermatomes are important in allowing doctors to create models of the cord that can be useful in diagnosing. Two major maps are accepted by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and remain frequently used. The trigeminal nerve , as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin areas which are connected to a specific nerve. In the case of spinal cord injury, pain may be experienced in a dermatome that is connected to that nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in specific spinal nerves. If you experience a neurologic condition or pain that involves the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by a single spinal nerve. The nerves transmit sensory, motor and autonomic information. They form part of the peripheral nervous system, that connects the brain to the other parts of the body. A dermatome may get affected because of a spinal lesion. If one of these is injured, it can be treated easily with a local anesthetic.
Dermatomes in the thoracic region have been labeled by letter-number combinations, which show how the region is connected along with the sensor nerve which supplies that area. For example C1 spinal nerve doesn’t have a dermatome. However, others spinal nerves have been labeled as C1-C8 and T9 is a reference to belly button. Dermatomes are layered horizontally on the trunk those on the extremities are typically in a longitudinal.
Dermatome Map
The dermatome map is an integral part of textbooks that cover anatomy. The dermatome map is not uniform both inside and inter-textbook. The names are inconsistent, and some textbooks feature distinct maps on different pages. This can be particularly challenging when the authors of different chapters differ in their choice of dermatome map. A majority of textbooks employ the Maps of Foerster, Keegan, and Garrett but do not include appropriate 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 the skin that receives sensory information from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly located, but they tend to dip more inferiorly than horizontally. This is an inherent variation and some tissues have more than one. Furthermore dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons in the dorsal limbs.
