What is a Dermatome?

The term “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes are important in allowing doctors to develop maps of the spinal cord that aid in the diagnosis. Two major maps are accepted by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are frequently employed. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.

Dermatomes are skin-like areas that are attached to a specific nerve bundle. When there is a spinal cord injury, pain can be experienced in a dermatome that is innervated by that nerve. Similarly, the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you suffer from nerve pain or neurological problem affecting the dermatome region, you need to consult a physician.

What are Some Examples of Dermatomes?

Dermatomes are segments of skin supplied by only one spinal nerve. These nerves relay sensory, motor and autonomic messages. They form part of the peripheral nervous system, that connects the brain to the all the body. Dermatomes can be affected by a spinal cord lesion. If one of these is injured, it can be easily treated with a local anesthetic.

The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate how the region is connected and the sensory nerve that supplies that region. For example C1’s spinal nerve does not possess a dermatome, however the other spinal nerves are labeled C1 – C8 and T9 is a reference with the belly button. Dermatomes are laid horizontally along the trunk, and dermatomes located that are located on the extremities are generally linear.

Dermatome Map

Dermatome maps are an integral part of textbooks teaching anatomy. The dermatome map is not consistent both within and inter-textbook. The names are inconsistent and some textbooks include various maps on different pages. This is particularly problematic in the event that the authors of various chapters differ in their choice of dermatome map. Most textbooks use maps of Foerster, Keegan, and Garrett but do not include the proper references. Additionally, four textbooks employ maps that do not have citations, such as one that only cites secondary sources.

Dermatomes are the regions of skin that receives sensory innervation from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip lower than horizontally. This is a natural variation, and certain tissue types are covered with more than one. Additionally, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons in the dorsal parts of the limbs.
