What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes are important in allowing doctors to construct diagrams of the spine that aid in the diagnosis. Two maps are widely accepted by medical experts. They are the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still commonly used. The trigeminal nerve and the 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, the pain could be felt in a dermatome that is connected to that nerve. The same is true for the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you experience a neurologic condition or pain that involves the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin supplied by a single spinal nerve. These nerves carry sensory, motor as well as autonomic information. They form an element of the peripheral nervous system, which connects the brain and other parts of the body. Dermatomes can get affected because of a spinal injury. If one of these dermatomes is injured, it can be easily treated with an local anesthetic.
The dermatomes of the thoracic region are identified using letter-number sequences that demonstrate the connection between the area and the sensory nerve which supplies that area. For example, the C1 spinal nerve doesn’t possess a dermatome, however all spinal nerves in the region are identified as C1-C8 T9, which corresponds with the belly button. Dermatomes are laid horizontally on the trunk, and dermatomes located on the extremities tend to be long.
Dermatome Map
Dermatome maps are the most common element in textbooks teaching anatomy. However, the dermatome map is not consistent both within and inter-textbook. The names are inconsistent, and some textbooks feature different maps on different pages. This can be particularly challenging when the authors of different chapters do not agree on the selection of dermatome maps. Many textbooks use the map of Foerster, Keegan, and Garrett however, they do not provide proper references. Additionally, four textbooks employ maps with no citations, and one of them is one that uses only secondary sources.
The dermatome is the area of skin that receives sensory innervation from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly situated, but they tend to dip lower than horizontally. This is a natural variation and some tissue types are covered with more than one. Also dorsal spinal rootlets could contain intrathecal intersegmental connections with sensory neurons of the dorsal limbs.
