What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help physicians to build models of the cord, which are useful for diagnosis. Two major maps are recognized by medical specialists. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and remain widely used. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.

Dermatomes are skin areas which are connected to a particular nerve bundle. In cases of spinal cord injuries, pain may be experienced in a dermatome that is controlled by the nerve. In the same way, the pain triggered by shingles outbreaks can be felt in particular spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin supplied by a single spinal nerve. These nerves relay motor, sensory as well as autonomic information. They form an element of the peripheral nerve system that connects the brain to the all the body. A dermatome may get affected because of a spinal cord injury. If one of these becomes injured, it could be easily treated with a local anesthetic.

The dermatomes of the thoracic region have been labeled using letter-number sequences that demonstrate the relationship between the area in question and the sensory nerve that serves the area. For example C1’s spinal nerve does not have a dermatome, but the other spinal nerves are labeled as C1-C8 and T9 refers to the belly button. Dermatomes are laid horizontally along the trunk, however, dermatomes in the extremities are usually longitudinal.

Dermatome Map

Dermatome maps are an integral part of textbooks teaching anatomy. 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 in the event that the authors of various chapters do not agree on the selection of dermatome map. A majority of textbooks employ the map of Foerster, Keegan, and Garrett however, they do not provide proper references. Furthermore, four textbooks make use of maps with no citations. This includes one that uses only secondary sources.

Dermatomes are the parts of skin that receives sensory input from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip more inferiorly than horizontally. This is a natural variation and some tissue types are covered with more than one. In addition to this, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons that originate from those limbs that are dorsal.
