What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the spinal cord. Dermatomes help doctors to develop maps of the spinal cord, which aid in the diagnosis. Two major maps are recognized by medical specialists. These are: the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still commonly utilized. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.

Dermatomes are skin-like areas that are attached to a specific nerve. In cases of spinal injury, pain can be experienced in a dermatome that is controlled by the nerve. Similar to the pain that is caused by an outbreak of shingles can be felt on specific spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin supplied by only one spinal nerve. The nerves transmit sensory, motor and autonomic messages. They form part of the peripheral nerve system that connects the brain to the rest of the body. A dermatome may be affected by a spinal injury. If one of these dermatomes gets injured, it is able to be treated easily with a local anesthetic.

Dermatomes in the thoracic region are labeled by letter-number combinations, which show how the region is connected in question and the sensory nerve that is responsible for that area. For example, the C1 spinal nerve does not have a dermatome, but others spinal nerves have been labeled C1-C8 T9, which corresponds to belly button. Dermatomes are layered horizontally on the trunk, while dermatomes on the extremities tend to be in a longitudinal.

Dermatome Map

Dermatome maps are an integral part of textbooks teaching anatomy. However, the dermatome map is not uniform both inside and inter-textbook. The names are inconsistent and some textbooks include different maps on various pages. This is particularly problematic when the authors of different chapters are not unified in their choice of dermatome maps. Most textbooks use diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide proper references. Furthermore, four textbooks make use of maps without citations, including one that only cites secondary sources.

Dermatomes are the areas of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip less inferiorly than horizontally. This is a natural variation, and some tissues may be covered by multiple dermatomes. Additionally dorsal spinal rootlets could have intrathecal intersegmental anastomoses to sensory neurons that originate from the dorsal limbs.
