What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes help doctors to develop images of spinal cord that are useful for diagnosis. Two major maps are accepted by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are often employed. The trigeminal and maxillary nerves are the two largest dermatomes.

Dermatomes are areas of skin that are attached to a specific nerve. In the case of spinal cord injury, pain can be experienced in a dermatome that is controlled by the nerve. Similar to the pain that is caused by shingles outbreaks is felt by specific spinal nerves. If you experience a pain or neurological condition involving the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is supplied by a single spinal nerve. The nerves transmit motor, sensory, as well as autonomic information. They form a part of the peripheral nerve system that connects the brain to the rest of the body. A dermatome may be affected by a spinal cord lesion. If one of these gets injured, it is able to be treated easily with a local anesthetic.

Dermatomes in the thoracic area are marked with letters-numbers that illustrate the connection between the region as well as the nerve which supplies that area. For instance C1 spinal nerve doesn’t have a dermatome, but those spinal nerves that are labeled as C1-C8 T9, which corresponds with the belly button. Dermatomes are laid horizontally on the trunk, while dermatomes in the extremities are usually long.

Dermatome Map

The dermatome map is one of the common features of textbooks that cover anatomy. The dermatome map is not uniform both inside and inter-textbook. Its name isn’t consistent and some textbooks include different maps on various pages. This can be particularly challenging when the authors of several chapters differ in their choice of dermatome map. Many textbooks use the Maps of Foerster, Keegan, and Garrett however, they do not provide proper references. Additionally, four textbooks employ maps without citations, including one that refers to only secondary sources.

Dermatomes are the regions of skin that receives sensory input from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly situated, but they tend to dip more inferiorly than horizontally. This is a natural variation and some tissues have more than one. Additionally dorsal spinal rootlets could have intrathecal intersegmental anastomoses to sensory neurons in the dorsal parts of the limbs.
