What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that is a part of the spine. Dermatomes are important in allowing doctors to create maps of the spinal cord, which are useful for diagnosis. Two major maps are regarded as valid by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are still frequently utilized. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.

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

What are Some Examples of Dermatomes?

Dermatomes are segments of skin supplied by the spinal nerve. These nerves relay sensory, motor and autonomic information. They form an element of the peripheral nerve system which connects the brain with the rest of the body. Dermatomes can get affected because of a spinal lesion. If one of these becomes injured, it could be easily treated with local anesthetic.

Dermatomes in the thoracic region are identified using letter-number sequences that demonstrate how the region is connected and the sensory nerve that supplies this area. For instance C1 spinal nerve does not possess a dermatome, however all spinal nerves in the region are labeled as C1-C8 T9, which corresponds to belly button. Dermatomes are layered in horizontally along the trunk, those that are located on the extremities are generally in a longitudinal.

Dermatome Map

The dermatome map is a common feature of textbooks that teach anatomy. However, the dermatome map is not uniform both inside and inter-textbook. The names are inconsistent as are some textbooks that have distinct maps on different pages. This can be particularly challenging in the event that the authors of various chapters do not agree on the selection of dermatome map. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett but do not include appropriate references. In addition, four textbooks utilize maps with no citations. This includes one that uses only secondary sources.

Dermatomes are the regions of skin that receives sensory innervation from the dorsal root of one spinal nerve. Dermatomes aren’t always evenly situated, but they tend to be more inferior than horizontally. This is a normal variation and some tissues are covered by more than one dermatome. Additionally dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons from those limbs that are dorsal.
