What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the spine. Dermatomes help doctors to develop diagrams of the spine that help in diagnosing. Two major maps are recognized by medical experts. There is the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are often utilized. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.

Dermatomes are areas of skin that are attached to a specific nerve. In cases of spinal cord injury, pain can be felt in a dermatome which is controlled 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 experience a nerve pain or neurological problem affecting the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are segments of skin that is provided by only one spinal nerve. These nerves relay sensory, motor as well as autonomic information. They form a part of the peripheral nerve system that connects the brain to the other parts of the body. A dermatome may suffer from a spinal cord lesion. If one of these becomes injured, it could be easily treated using the use of a local anesthetic.

Dermatomes in the thoracic region have been labeled by letter-number combinations, which show the connection between the area as well as the nerve that supplies this area. For instance the C1 spinal nerve does not have a dematome, however the other spinal nerves are identified as C1-C8 T9, which corresponds to the belly button. Dermatomes are laid horizontally on the trunk, those on the extremities tend to be in a longitudinal.

Dermatome Map

The dermatome map is the most common element in textbooks teaching anatomy. However, the dermatome maps is not consistent both within and inter-textbook. The names are inconsistent and some textbooks include different maps on different pages. This can be particularly challenging when the authors of different chapters are not unified in their choice of dermatome maps. Many textbooks use the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide adequate references. In addition, four textbooks utilize maps with no citations. This includes one that uses only secondary sources.

Dermatomes are the regions of skin that receives sensory innervation from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly located, but they tend to be more inferior than horizontally. This is a natural variation and some tissues have more than one. Additionally dorsal spinal nerve roots may contain intrathecal intersegmental connections with sensory neurons from the dorsal limbs.
