What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the spine. Dermatomes can help doctors to construct images of spinal cord that aid in the diagnosis. Two major maps are regarded as valid by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are often used. 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. 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 particular spinal nerves. If you feel discomfort or neurological issue involving the dermatome, you should consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin that is provided by a single spinal nerve. These nerves carry motor, sensory, and autonomic signals. They form part of the peripheral nervous system, which connects the brain with the other parts of the body. A dermatome may suffer from a spinal cord injury. When one of these dermatomes becomes injured, it can be easily treated with the use of a local anesthetic.

Dermatomes in the thoracic region have been labeled using letter-number sequences that demonstrate the connection between the region as well as the nerve that is responsible for that area. For instance C1 spinal nerve doesn’t possess a dermatome, however the other spinal nerves are labeled as C1-C8 and T9 is a reference to the belly button. Dermatomes are layered in vertically on the trunk while dermatomes in the extremities are usually long.

Dermatome Map

The dermatome map is one of the common features of textbooks that teach anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. Its name isn’t consistent and some textbooks include different maps on various pages. This is particularly problematic when the authors of multiple chapters are not unified in their choice of dermatome maps. Most textbooks use maps of Foerster, Keegan, and Garrett but do not include proper references. In addition, four textbooks utilize maps with no citations, and one of them is one that refers to only secondary sources.

The dermatome is the area of the skin that receives sensory information from the dorsal root of one 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. Furthermore dorsal spinal rootlets could contain intrathecal intersegmental connections with sensory neurons that originate from the dorsal limbs.
