What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the spine. Dermatomes can help doctors to create images of spinal cord, which aid in the diagnosis. Two major maps are regarded as valid by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain frequently employed. The trigeminal and maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas which are connected to a specific nerve bundle. In cases of spinal injury, pain can be felt in a dermatome that is surrounded by the nerve. The same is true for the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you are experiencing pain or neurological condition involving the dermatome, it is recommended that you visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is provided by one spinal nerve. These nerves provide sensory, motor, and autonomic signals. They form part of the peripheral nerve system which connects brain and all the body. Dermatomes can suffer from a spinal injury. If one of these dermatomes is injured, it can be easily treated with the use of a local anesthetic.
Dermatomes in the thoracic area are marked with letters-numbers that illustrate how the region is connected in question and the sensory nerve that is responsible for that region. For instance C1’s spinal nerve doesn’t have a dermatome. However, those spinal nerves that are labeled C1-C8 T9, which corresponds to belly button. Dermatomes are laid vertically on the trunk however, dermatomes that are located on the extremities are generally linear.
Dermatome Map
The dermatome map is an integral part of textbooks that teach anatomy. But, the map is inconsistency both within and inter-textbook. The name is not consistent, and some textbooks feature various maps on different pages. This is particularly problematic in the event that the authors of various chapters do not agree on the selection of dermatome map. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett but do not include the proper references. In addition, four textbooks utilize maps that do not have citations, such as one that uses only secondary sources.
Dermatomes are the parts of skin that receives sensory innervation from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to be more inferior than horizontally. This is a natural variation, and some tissues may be covered by multiple dermatomes. Furthermore dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons from Dorsal limbs.
