What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes can help doctors to develop diagrams of the spine that aid in the diagnosis. Two maps are widely accepted by medical professionals. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and remain widely used. The trigeminal nerve and the maxillary nerve are the largest dermatomes.

Dermatomes are skin areas that are attached to a particular nerve bundle. When there is a spinal cord injury, pain may be felt in a dermatome that is innervated by that nerve. Similar to the pain that is caused by shingles outbreaks can be felt on specific spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?

A dermatome is a segment of skin that is supplied by the spinal nerve. The nerves transmit motor, sensory and autonomic signals. They form part of the peripheral nerve system, that connects the brain to the other parts of the body. Dermatomes can become affected due to a spinal injury. When one of these dermatomes is injured, it can be easily treated with an local anesthetic.

Dermatomes in the thoracic region are identified with letter-number combinations that show the connection between the region in question and the sensory nerve that supplies this area. For example the C1 spinal nerve doesn’t have a dermatome, but others spinal nerves have been labeled C1 – C8 and T9 is a reference with the belly button. Dermatomes are layered in horizontally along the trunk, those on the extremities tend to be longitudinal.

Dermatome Map

Dermatome maps are an integral part of textbooks teaching anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. Its naming is inconsistent, and some textbooks feature distinct maps on different pages. This is especially problematic when the authors of different chapters differ in their choice of dermatome maps. A majority of textbooks employ the map of Foerster, Keegan, and Garrett however, they do not provide proper references. Moreover, four textbooks use maps with no citations. This includes one that cites only secondary sources.

Dermatomes are the regions of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly situated, but they tend to dip more inferiorly than horizontally. This is a normal variation and some tissue types are covered with more than one. Additionally, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons of the dorsal parts of the limbs.
