What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that covers your spinal cord. Dermatomes play a crucial role in allowing physicians to build images of spinal cord, which help in diagnosing. Two maps are widely accepted by medical specialists. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are frequently employed. The trigeminal nerve , as well as the maxillary nerve are the biggest dermatomes.

Dermatomes are areas of skin which are connected to a particular nerve bundle. In the case of spinal cord injury, pain may be experienced in a dermatome that is surrounded by the nerve. Similar to the pain that is caused by an outbreak of shingles can be felt on specific spinal nerves. If you suffer from discomfort or neurological issue involving the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?

A dermatome is a segment of skin that is supplied by only one spinal nerve. These nerves provide motor, sensory and autonomic signals. They form an element of the peripheral nervous system, which connects brain and all the body. A dermatome may suffer from a spinal lesion. If one of these is injured, it can be easily treated with an local anesthetic.

The dermatomes of the thoracic area are marked by letter-number combinations, which show the connection between the region along with the sensor nerve that is responsible for the area. For instance the C1 spinal nerve doesn’t have a dermatome, but all spinal nerves in the region are labeled as C1-C8 and T9 is a reference to the belly button. Dermatomes are laid horizontally on the trunk those that are located on the extremities are generally longitudinal.

Dermatome Map

Dermatome maps are an integral part of textbooks that cover anatomy. But, the map is inconsistency both within and inter-textbook. Its name isn’t consistent, and some textbooks feature different maps on various pages. This is especially problematic in the event that the authors of various chapters differ in their choice of dermatome map. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett but don’t include appropriate references. Moreover, four textbooks use maps that do not have citations, such as one that cites only secondary sources.

Dermatomes are the parts of skin that receives sensory innervation from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to be more inferior than horizontally. This is a natural variation and certain tissues are covered by more than one dermatome. Furthermore, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons from those limbs that are dorsal.
