Spinal Nerve Radiculopathy Nerve – If you’ve ever wanted to know how the human dermatome chart looks, you’ve come to the right spot. Before we get to our map, we’ll discuss what is a dermatome. What are the different kinds? The most important thing is why is it necessary to know about dermatomes in order to know more about 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 the spine. Dermatomes play a crucial role in allowing doctors to create models of the cord, which help in diagnosing. Two major maps are regarded as valid by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s, and are widely used. The trigeminal and maxillary nerve are the largest dermatomes.
Dermatomes are skin regions that are attached to a particular nerve bundle. When there is a spinal cord injury, pain can 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 feel discomfort or neurological issue involving the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is provided by the spinal nerve. These nerves relay sensory, motor, and autonomic signals. They form an element of the peripheral nervous system which connects the brain and other parts of the body. Dermatomes can be affected by a spinal cord injury. If one of these dermatomes becomes injured, it could be easily treated with local anesthetic.
Dermatomes in the thoracic region have been labeled with letters-numbers that illustrate the connection between the area and the sensory nerve that supplies that region. For example, the C1 spinal nerve does not have a dermatome. However, all spinal nerves in the region are labeled C1-C8 and T9 is a reference to belly button. Dermatomes are layered in horizontally along the trunk, those in the extremities are usually in a longitudinal.
Dermatome Map
The dermatome map is one of the common features of textbooks that cover anatomy. However, the dermatome map is not consistent both within and inter-textbook. Its naming is inconsistent, and some textbooks feature different maps on different pages. This is especially problematic in the event that the authors of various chapters disagree on the choice of dermatome maps. Many textbooks use the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide adequate references. Additionally, four textbooks employ maps with no citations, and one of them is one that uses only secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal root of one spinal nerve. The dermatomes are not uniformly located, but they tend to be more inferior than horizontally. This is an inherent variation and certain tissues have more than one. Also dorsal spinal rootlets could contain intrathecal intersegmental connections with sensory neurons in the dorsal parts of the limbs.
