What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes help doctors to construct maps of the spinal cord, which aid in the diagnosis. Two major maps are accepted by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are often utilized. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.

Dermatomes are skin-like areas that connect to a specific nerve. In the case of spinal cord injuries, pain may be experienced in a dermatome that is connected to that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in specific spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are segments of skin supplied by the spinal nerve. These nerves carry sensory, motor, as well as autonomic information. They form a part of the peripheral nervous system which connects brain and all the body. A dermatome may become affected due to a spinal lesion. If one of these dermatomes is injured, it can be treated easily with a local anesthetic.

Dermatomes in the thoracic region are labeled by letter-number combinations, which show the connection between the area and the sensory nerve that serves the area. For instance, the C1 spinal nerve doesn’t have a dermatome. However, all spinal nerves in the region are labeled as C1-C8 and T9 is a reference to belly button. Dermatomes are laid vertically on the trunk those 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 inconsistent both intra and inter-textbook. The names are inconsistent, and some textbooks feature different maps on different pages. This is especially problematic when the authors of several chapters are not unified in their choice of dermatome map. The majority of textbooks utilize the diagrams drawn by Foerster, Keegan, and Garrett but do not include proper references. Moreover, four textbooks use maps without citations, including one that only cites secondary sources.

The dermatome is the area of the skin that receives sensory information from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip less 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 those limbs that are dorsal.
