What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes help physicians to build diagrams of the spine, which are useful for diagnosis. Two major maps are regarded as valid by medical professionals. They are the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still widely utilized. 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 bundle. In cases of spinal cord injuries, pain may be felt in a dermatome which is connected to that nerve. Similarly, the pain caused by an outbreak of shingles is felt by 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?
Dermatomes are a part of skin supplied by one spinal nerve. These nerves relay sensory, motor, and autonomic signals. They form a part of the peripheral nerve system, that connects the brain to the other parts of the body. A dermatome may suffer from a spinal injury. If one of these dermatomes is injured, it can be easily treated with local anesthetic.
Dermatomes in the thoracic area are marked by letter-number combinations, which show the connection between the area in question and the sensory nerve which supplies that area. For instance the C1 spinal nerve doesn’t possess a dermatome, however all spinal nerves in the region are identified as C1-C8, while T9 corresponds to belly button. Dermatomes are layered in vertically on the trunk those on the extremities are typically linear.
Dermatome Map
The dermatome map is the most common element in textbooks teaching anatomy. However, the dermatome map is inconsistency both within and inter-textbook. The names are inconsistent as are some textbooks that have various maps on different pages. This can be particularly challenging when the authors of different chapters do not agree on the selection of dermatome map. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett but don’t include the proper references. In addition, four textbooks utilize maps with no citations, and one of them is one that refers to only secondary sources.
Dermatomes are the areas of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t evenly situated, but they tend to dip lower than horizontally. This is a natural variation, and some tissues are covered by more than one dermatome. Furthermore dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons of Dorsal limbs.
