What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes are important in allowing doctors to construct maps of the spinal cord, which can be useful in diagnosing. Two major maps are recognized by medical specialists. They are the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are still commonly used. The trigeminal and maxillary nerves are the two largest dermatomes.

Dermatomes are skin-like areas that connect to a particular nerve. In cases of spinal injuries, pain may be felt in a dermatome, which is surrounded by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt in particular spinal nerves. If you feel pain or neurological condition involving the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?

A dermatome is a segment of skin that is provided by the spinal nerve. The nerves transmit motor, sensory, and autonomic signals. They form part of the peripheral nerve system, which connects the brain and all the body. A dermatome may get affected because of a spinal injury. When one of these dermatomes becomes injured, it could be easily treated with the use of a local anesthetic.

The dermatomes of the thoracic region are identified using letter-number sequences that demonstrate the connection between the region along with the sensor nerve that serves the area. For instance C1 spinal nerve does not have a dermatome, but the other spinal nerves are labeled C1 – C8, while T9 corresponds to the belly button. Dermatomes are layered in horizontally on the trunk, while dermatomes that are located on the extremities are generally linear.

Dermatome Map

Dermatome maps are an integral part of textbooks teaching anatomy. However, the dermatome map is not consistent both within and inter-textbook. The name is not consistent 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 differ in their choice of dermatome map. Many textbooks use the maps of Foerster, Keegan, and Garrett but do not include appropriate references. Furthermore, four textbooks make use of maps with no citations. This includes one that uses only secondary sources.

The dermatome is the area of skin that receives sensory innervation from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip more inferiorly than horizontally. This is a natural variation, and certain tissues are covered by more than one dermatome. Additionally dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal parts of the limbs.
