What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that is a part of the spine. Dermatomes play a crucial role in allowing doctors to create diagrams of the spine, which are useful for diagnosis. Two maps are widely accepted by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are frequently employed. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.

Dermatomes are skin areas that are linked to a particular nerve bundle. In cases of spinal injury, pain may be felt in a dermatome that is surrounded by the nerve. The same is true for the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you feel neurologic condition or pain that involves the dermatome area, you must visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin supplied by a single spinal nerve. The nerves transmit sensory, motor and autonomic information. They form an element of the peripheral nerve system, which connects the brain and other parts of the body. Dermatomes can be affected by a spinal lesion. When one of these dermatomes becomes injured, it can be easily treated using local anesthetic.

Dermatomes in the thoracic region are identified with letter-number combinations that show the relationship between the area and the sensory nerve that supplies the area. For example C1 spinal nerve does not have a dematome, however others spinal nerves have been identified as C1-C8 and T9 refers to the belly button. Dermatomes are layered horizontally on the trunk those in the extremities are usually in a longitudinal.

Dermatome Map

Dermatome maps are an integral part of textbooks that cover anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. The name is not consistent and certain textbooks have different maps on various pages. This is particularly problematic when the authors of multiple chapters disagree on the choice of dermatome map. The majority of textbooks utilize the map of Foerster, Keegan, and Garrett but don’t include appropriate references. In addition, four textbooks utilize maps with no citations. This includes one that refers to only secondary sources.

Dermatomes are the regions of skin that receives sensory input from the dorsal root of a spinal nerve. The dermatomes are not uniformly placed, however they tend to be more inferior than horizontally. This is a natural variation and some tissues may be covered by multiple dermatomes. Furthermore dorsal spinal nerve roots may contain intrathecal intersegmental connections with sensory neurons from the dorsal parts of the limbs.
