What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes play a crucial role in allowing doctors to develop diagrams of the spine, which are useful for diagnosis. Two maps are widely accepted by medical specialists. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain commonly employed. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.

Dermatomes are skin areas that are linked to a specific nerve bundle. In cases of spinal injuries, pain may be felt in a dermatome, which is connected to that nerve. Similarly, the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome region, you need to consult with a physician.

What are Some Examples of Dermatomes?

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

Dermatomes in the thoracic region have been labeled using letter-number sequences that demonstrate the connection between the region and the sensory nerve that is responsible for that region. For instance C1’s spinal nerve does not possess a dermatome, however others spinal nerves have been identified as C1-C8 and T9 is a reference with the belly button. Dermatomes are layered in horizontally on the trunk, and dermatomes located that are located on the extremities are generally linear.

Dermatome Map

The dermatome map is an integral part of textbooks that teach anatomy. However, the dermatome maps is not consistent both within and inter-textbook. Its name isn’t consistent and certain textbooks have distinct maps on different pages. This is particularly problematic in the event that the authors of various chapters do not agree on the selection of dermatome maps. A majority of textbooks employ the map of Foerster, Keegan, and Garrett however, they do not provide appropriate references. Furthermore, four textbooks make use of maps with no citations. This includes one that cites only secondary sources.

Dermatomes are the areas of skin that receives sensory stimulation from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly situated, but they tend to dip less inferiorly than horizontally. This is a natural variation, and certain tissue types are covered with more than one. Additionally dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons that originate from the dorsal limbs.
