What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes are important in allowing doctors to develop maps of the spinal cord that aid in the diagnosis. Two maps are widely accepted by medical specialists. These are: the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and remain often utilized. The trigeminal and maxillary nerves are the two largest dermatomes.

Dermatomes are skin areas that are linked to a particular nerve bundle. When there is a spinal cord injury, pain can be felt in a dermatome, which is controlled by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you are experiencing nerve pain or neurological problem affecting the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?

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

The dermatomes of the thoracic region are identified using letter-number sequences that demonstrate the relationship between the area along with the sensor nerve which supplies the area. For example C1’s spinal nerve does not possess a dermatome, however others spinal nerves have been labeled C1 – C8 and T9 is a reference to the belly button. Dermatomes are laid horizontally on the trunk, however, dermatomes that are located on the extremities are generally long.

Dermatome Map

Dermatome maps are a common feature of textbooks that teach anatomy. But, the map is inconsistent both intra and inter-textbook. The name is not consistent and certain textbooks have different maps on different pages. This is particularly problematic when the authors of different chapters are not unified in their choice of dermatome maps. Most textbooks use map of Foerster, Keegan, and Garrett but do not include the proper references. Furthermore, four textbooks make use of maps that do not have citations, such as one that refers to only secondary sources.

Dermatomes are the areas of skin that receives sensory stimulation from the dorsal root of one spinal nerve. Dermatomes aren’t evenly located, but they tend to be more inferior than horizontally. This is a normal variation and certain tissues may be covered by multiple dermatomes. In addition to this, dorsal spinal rootlets may contain intrathecal intersegmental connections with sensory neurons that originate from those limbs that are dorsal.
