What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes are important in allowing doctors to create images of spinal cord that help in diagnosing. Two maps are widely accepted by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain commonly employed. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.

Dermatomes are skin areas that connect to a specific nerve bundle. In cases of spinal injury, pain can be felt in a dermatome, which is connected to that nerve. Similarly, the pain caused by an outbreak of shingles is felt by specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome, you should consult a physician.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is supplied by one spinal nerve. These nerves relay motor, sensory, and autonomic messages. They form a part of the peripheral nerve system, which connects the brain and all the body. A dermatome may become affected due to a spinal cord lesion. If one of these becomes injured, it can be easily treated using the use of a local anesthetic.

The dermatomes of the thoracic region are identified with letter-number combinations that show the relationship between the area as well as the nerve that serves that area. For instance C1 spinal nerve doesn’t possess a dermatome, however those spinal nerves that are labeled C1 – C8 and T9 is a reference with the belly button. Dermatomes are laid horizontally on the trunk while dermatomes on the extremities are typically in a longitudinal.

The dermatome map is one of the common features of textbooks that teach anatomy. However, the dermatome maps is not consistent both within and inter-textbook. The name is not consistent and certain textbooks have distinct maps on different pages. This is especially problematic in the event that the authors of various chapters disagree on the choice of dermatome map. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett but don’t include proper references. Additionally, four textbooks employ maps with no citations. This includes one that cites only secondary sources.

Dermatomes are the areas of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly placed, however they tend to be more inferior than horizontally. This is a natural variation and certain tissue types are covered with more than one. Additionally, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons in Dorsal limbs.
