What is a Dermatome?

The term “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes can help doctors to construct models of the cord that are useful for diagnosis. Two major maps are recognized by medical professionals. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still frequently used. The trigeminal nerve as well as the maxillary nerve are the biggest dermatomes.

Dermatomes are skin areas that are attached to a specific nerve bundle. In cases of spinal injury, pain can be felt in a dermatome that is controlled by the nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in specific spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin that is supplied by only one spinal nerve. These nerves provide sensory, motor and autonomic signals. They form a part of the peripheral nerve system which connects brain and other parts of the body. Dermatomes can get affected because of a spinal injury. If one of these becomes injured, it could be treated easily with the use of a local anesthetic.

The dermatomes of the thoracic region are labeled with letter-number combinations that show the connection between the area and the sensory nerve that serves that region. For example C1 spinal nerve does not possess a dermatome, however all spinal nerves in the region are labeled as C1-C8 and T9 is a reference with the belly button. Dermatomes are layered horizontally on the trunk, while dermatomes that are located on the extremities are generally linear.

Dermatome Map

The dermatome map is a common feature of textbooks teaching anatomy. However, the dermatome map is not consistent both within and inter-textbook. Its naming is inconsistent, and some textbooks feature distinct maps on different pages. This can be particularly challenging in the event that the authors of various chapters differ in their choice of dermatome maps. Many textbooks use the diagrams drawn by Foerster, Keegan, and Garrett but do not include appropriate references. Moreover, four textbooks use maps with no citations. This includes one that refers to only secondary sources.

Dermatomes are the areas of skin that receives sensory stimulation from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly situated, but they tend to be more inferior than horizontally. This is a natural variation and some tissue types are covered with more than one. Furthermore, dorsal spinal rootlets may contain intrathecal intersegmental connections with sensory neurons in the dorsal limbs.
