What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help doctors to create models of the cord, which aid in the diagnosis. Two maps are widely accepted by medical specialists. There is the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are frequently employed. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.

Dermatomes are areas of skin which are connected to a specific nerve bundle. In the case of spinal cord injury, pain may be experienced in a dermatome that is surrounded by the nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in specific spinal nerves. If you experience a neurologic condition or pain that involves the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is supplied by a single spinal nerve. These nerves relay sensory, motor, as well as autonomic information. They form part of the peripheral nerve system, which connects the brain and all the body. A dermatome may suffer from a spinal cord lesion. When one of these dermatomes is injured, it can be easily treated using an local anesthetic.

Dermatomes in the thoracic region are identified with letters-numbers that illustrate the connection between the region as well as the nerve which supplies that area. For instance C1’s spinal nerve does not have a dematome, however the other spinal nerves are identified as C1-C8, while T9 corresponds with the belly button. Dermatomes are layered in horizontally along the trunk, and dermatomes located that are located on the extremities are generally long.

Dermatome maps are one of the common features of textbooks that teach anatomy. The dermatome map is not uniform both inside and inter-textbook. The names are inconsistent and some textbooks include different maps on various pages. This is especially problematic when the authors of different chapters do not agree on the selection of dermatome maps. Most textbooks use map of Foerster, Keegan, and Garrett however they don’t provide appropriate references. Additionally, four textbooks employ maps with no citations. This includes one that only cites secondary sources.

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