What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes play a crucial role in allowing physicians to build diagrams of the spine, which help in diagnosing. Two major maps are recognized by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain frequently utilized. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.

Dermatomes are areas of skin which are connected to a particular nerve bundle. When there is a spinal cord injury, the pain could be felt in a dermatome, which is controlled by the nerve. The same is true for the pain caused by an outbreak of shingles is felt by specific spinal nerves. If you are experiencing neurologic condition or pain that involves the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is provided by one spinal nerve. These nerves relay sensory, motor, as well as autonomic information. They form a part of the peripheral nervous system, which connects the brain and other parts of the body. Dermatomes can become affected due to a spinal lesion. If one of these gets injured, it is able to be easily treated with a local anesthetic.

Dermatomes in the thoracic region have been labeled with letter-number combinations that show the connection between the area along with the sensor nerve that serves that area. For instance C1 spinal nerve does not have a dermatome, but the other spinal nerves are labeled C1-C8 and T9 is a reference to belly button. Dermatomes are layered in horizontally on the trunk, while dermatomes on the extremities are typically in a 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. The name is not consistent and some textbooks include various maps on different pages. This is especially problematic when the authors of multiple chapters are not unified in their choice of dermatome map. Most textbooks use Maps of Foerster, Keegan, and Garrett but don’t include adequate references. Moreover, four textbooks use maps with no citations, and one of them is one that cites only secondary sources.

The dermatome is the area of skin that receives sensory input from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly found, but they tend to dip lower than horizontally. This is a natural variation, and certain tissues may be covered by multiple dermatomes. Also dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons in the dorsal limbs.
