What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes help doctors to develop images of spinal cord that are useful for diagnosis. Two major maps are recognized by medical professionals. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are frequently utilized. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas which are connected to a specific nerve bundle. In the case of spinal cord injury, the pain could be felt in a dermatome which is controlled by the nerve. Similarly, the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you feel pain or neurological condition involving the dermatome area, you must consult with a physician.

Dermatomes are segments of skin supplied by one spinal nerve. The nerves transmit motor, sensory, and autonomic signals.

If one of these is injured, it can be easily treated with the use of a local anesthetic.
The dermatomes of the thoracic area are marked by letter-number combinations, which show how the region is connected along with the sensor nerve that is responsible for this area. For example C1 spinal nerve does not have a dermatome. However, those spinal nerves that are labeled as C1-C8 and T9 refers with the belly button. Dermatomes are laid vertically on the trunk and dermatomes located that are located on the extremities are generally linear.
Dermatome Map
The dermatome map is a common feature of textbooks teaching anatomy. However, the dermatome map is not consistent both within and inter-textbook. Its naming is inconsistent as are some textbooks that have various maps on different pages. This can be particularly challenging in the event that the authors of various chapters are not unified in their choice of dermatome maps. A majority of textbooks employ the Maps of Foerster, Keegan, and Garrett but don’t include proper 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 the skin that receives sensory information from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip lower than horizontally. This is a natural variation, and certain tissue types are covered with more than one. Additionally dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons of Dorsal limbs.
