What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the spine. Dermatomes are important in allowing doctors to construct models of the cord that are useful for diagnosis. Two major maps are recognized by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain often utilized. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that are linked to a specific nerve bundle. In the case of spinal cord injuries, pain may be experienced in a dermatome that is surrounded by the nerve. In the same way, the pain triggered by shingles outbreaks is felt by specific spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by one spinal nerve. These nerves carry motor, sensory, and autonomic signals. They form part of the peripheral nervous system, which connects brain and other parts of the body. A dermatome may get affected because of a spinal cord injury. If one of these gets injured, it is able to be treated easily with a local anesthetic.
The dermatomes of the thoracic region are labeled with letters-numbers that illustrate the connection between the area along with the sensor nerve that serves that region. For example C1 spinal nerve does not have a dematome, however those spinal nerves that are identified as C1-C8 and T9 is a reference to the belly button. Dermatomes are laid horizontally on the trunk and dermatomes located that are located on the extremities are generally linear.
Dermatome Map
Dermatome maps are an integral part of textbooks teaching anatomy. However, the dermatome map is inconsistency both within and inter-textbook. The names are inconsistent as are some textbooks that have distinct maps on different pages. This is particularly problematic when the authors of multiple chapters are not unified in their choice of dermatome map. A majority of textbooks employ the Maps of Foerster, Keegan, and Garrett however, they do not provide the proper references. Furthermore, four textbooks make use of maps with no citations. This includes one that uses only secondary sources.
Dermatomes are the regions of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to be more inferior than horizontally. This is a natural variation, and certain tissue types are covered with more than one. In addition to this, dorsal spinal rootlets may have intrathecal intersegmental anastomoses with sensory neurons from Dorsal limbs.
