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 are important in allowing doctors to construct diagrams of the spine that help in diagnosing. Two major maps are accepted by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are widely used. The trigeminal nerve , as well as the maxillary nerve are the biggest dermatomes.

Dermatomes are skin areas which are connected to a specific nerve bundle. When there is a spinal cord injuries, pain may be felt in a dermatome that is connected to that nerve. The same is true for the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you suffer from discomfort or neurological issue involving the dermatome region, you need to consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is provided by only one spinal nerve. These nerves carry sensory, motor, and autonomic messages. They form an element of the peripheral nerve system, that connects the brain to the other parts of the body. Dermatomes can suffer from a spinal lesion. If one of these dermatomes becomes injured, it could be treated easily with local anesthetic.

The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate the relationship between the area as well as the nerve that is responsible for that area. For instance C1’s spinal nerve doesn’t have a dermatome. However, others spinal nerves have been labeled C1 – C8 and T9 refers to the belly button. Dermatomes are laid horizontally on the trunk, and dermatomes located on the extremities tend to be longitudinal.

Dermatome Map

The dermatome map is a common feature of textbooks teaching anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. Its name isn’t consistent, and some textbooks feature various maps on different pages. This can be particularly challenging when the authors of several chapters do not agree on the selection of dermatome map. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett however they don’t provide the proper references. Additionally, four textbooks employ maps with no citations, and one of them is one that only cites secondary sources.

Dermatomes are the regions of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip more inferiorly than horizontally. This is a natural variation, and some tissues may be covered by multiple dermatomes. Also dorsal spinal rootlets could have intrathecal intersegmental anastomoses with sensory neurons that originate from the dorsal limbs.
