What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes play a crucial role in allowing doctors to create models of the cord that can be useful in diagnosing. Two maps are widely accepted by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are still frequently employed. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin-like areas which are connected to a specific nerve. In the case of spinal cord injury, pain can be felt in a dermatome which is connected to that nerve. Similarly, the pain caused by shingles outbreaks can be felt in particular 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 segments of skin supplied by the spinal nerve. These nerves provide sensory, motor and autonomic signals. They form a part of the peripheral nerve system, that connects the brain to the all the body. A dermatome may get affected because of a spinal cord lesion. When one of these dermatomes gets injured, it is able to be easily treated using an local anesthetic.
The dermatomes of the thoracic region have been labeled with letter-number combinations that show the connection between the area along with the sensor nerve that serves this area. For instance, the C1 spinal nerve does not have a dermatome, but others spinal nerves have been identified as C1-C8 T9, which corresponds to the belly button. Dermatomes are laid vertically on the trunk those that are located on the extremities are generally in a longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks that cover anatomy. However, the dermatome maps is not uniform both inside and inter-textbook. Its naming is inconsistent as are some textbooks that have different maps on various pages. This is especially problematic when the authors of different chapters differ in their choice of dermatome maps. The majority of textbooks utilize the map of Foerster, Keegan, and Garrett however they don’t provide adequate references. Additionally, four textbooks employ maps that do not have citations, such as one that uses only secondary sources.
The dermatome is the area of skin that receives sensory stimulation from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip lower than horizontally. This is a natural variation and some tissues may be covered by multiple dermatomes. In addition to this dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons in those limbs that are dorsal.
