What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes can help physicians to build images of spinal cord that help in diagnosing. Two major maps are recognized by medical experts. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and remain often employed. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.

Dermatomes are skin-like areas that are linked to a particular nerve bundle. In the case of spinal cord injury, pain can be felt in a dermatome which is surrounded by the nerve. Similarly, the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?

Dermatomes are segments of skin that is provided by one spinal nerve. These nerves relay sensory, motor and autonomic information. They form part of the peripheral nerve system, that connects the brain to the other parts of the body. A dermatome may suffer from a spinal cord injury. When one of these dermatomes gets injured, it is able to be easily treated using the use of a local anesthetic.

Dermatomes in the thoracic region are labeled using letter-number sequences that demonstrate the connection between the area as well as the nerve which supplies this area. For instance the C1 spinal nerve doesn’t possess a dermatome, however others spinal nerves have been labeled C1 – C8 T9, which corresponds with the belly button. Dermatomes are layered in horizontally on the trunk while dermatomes in the extremities are usually in a longitudinal.

Dermatome Map

The dermatome map is a common feature of textbooks that cover anatomy. The dermatome map is not consistent both within and inter-textbook. The names are inconsistent as are some textbooks that have various maps on different pages. This is especially problematic when the authors of several chapters are not unified in their choice of dermatome maps. Many textbooks use the map of Foerster, Keegan, and Garrett however, they do not provide proper references. Additionally, four textbooks employ maps with no citations. This includes one that uses only secondary sources.

The dermatome is the area of skin that receives sensory input from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly located, but they tend to be more inferior than horizontally. This is a normal variation and some tissues have more than one. Furthermore, dorsal spinal rootlets may contain intrathecal intersegmental connections with sensory neurons of those limbs that are dorsal.
