What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes are important in allowing doctors to develop diagrams of the spine, which are useful for diagnosis. Two maps are widely accepted by medical professionals. These are: the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still commonly utilized. The trigeminal nerve and the maxillary nerve are the largest dermatomes.

Dermatomes are skin-like areas that are linked to a specific nerve bundle. In cases of spinal cord injuries, pain may be felt in a dermatome, which 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 experience a nerve pain or neurological problem affecting the dermatome region, you need to consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin that is provided by only one spinal nerve. These nerves provide motor, sensory and autonomic messages. They form an element of the peripheral nervous system that connects the brain to the all the body. Dermatomes can become affected due to a spinal cord injury. If one of these becomes injured, it could be treated easily with an local anesthetic.

The dermatomes of the thoracic area are marked using letter-number sequences that demonstrate the relationship between the area and the sensory nerve that supplies that area. For instance C1 spinal nerve does not possess a dermatome, however those spinal nerves that are labeled C1 – C8 T9, which corresponds with the belly button. Dermatomes are laid horizontally along the trunk, however, dermatomes on the extremities are typically in a longitudinal.

Dermatome Map

Dermatome maps are an integral part of textbooks that cover anatomy. However, the dermatome map is inconsistency both within and inter-textbook. Its naming is inconsistent as are some textbooks that have distinct maps on different pages. This is especially problematic when the authors of different chapters are not unified in their choice of dermatome map. Many textbooks use the Maps of Foerster, Keegan, and Garrett but don’t include adequate references. In addition, four textbooks utilize maps with no citations, and one of them is one that uses only secondary sources.

Dermatomes are the areas of skin that receives sensory input from the dorsal root of one spinal nerve. The dermatomes are not uniformly situated, but they tend to dip more inferiorly than horizontally. This is a normal variation and certain tissues have more than one. Furthermore dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal limbs.
