What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes help doctors to construct images of spinal cord that can be useful in diagnosing. Two maps are widely accepted by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still commonly employed. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.

Dermatomes are areas of skin that connect to a particular nerve. In cases of spinal cord injury, pain may be felt in a dermatome, which is innervated by that nerve. The same is true for the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you feel pain or neurological condition involving the dermatome, it is recommended that you visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin supplied by only one spinal nerve. These nerves carry motor, sensory and autonomic signals. They form an element of the peripheral nerve system which connects the brain and rest of the body. A dermatome may suffer from a spinal cord injury. If one of these is injured, it can be easily treated with an local anesthetic.

The dermatomes of the thoracic region are labeled with letter-number combinations that show the connection between the region and the sensory nerve that supplies that region. For example the C1 spinal nerve does not have a dematome, however those spinal nerves that are labeled C1 – C8 and T9 is a reference to belly button. Dermatomes are layered in horizontally on the trunk, and dermatomes located that are located on the extremities are generally long.

Dermatome Map

The dermatome map is one of the common features of textbooks that teach anatomy. However, the dermatome map is inconsistency both within and inter-textbook. Its name isn’t consistent and some textbooks include different maps on different pages. This can be particularly challenging when the authors of multiple chapters differ in their choice of dermatome maps. Most textbooks use map 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 only cites secondary sources.

The dermatome is the area of skin that receives sensory input from the dorsal branch of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip more inferiorly than horizontally. This is an inherent variation and some tissues are covered by more than one dermatome. In addition to this dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal parts of the limbs.
