What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes play a crucial role in allowing doctors to create images of spinal cord that are useful for diagnosis. Two major maps are recognized by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are often used. The trigeminal nerve and the maxillary nerve are the largest dermatomes.

Dermatomes are skin regions which are connected to a particular nerve bundle. In cases of spinal injuries, pain may be experienced in a dermatome that is innervated by that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt on specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin that is provided by a single spinal nerve. These nerves relay motor, sensory and autonomic information. They form an element of the peripheral nerve system, which connects the brain and other parts of the body. Dermatomes can get affected because of a spinal lesion. If one of these dermatomes gets injured, it is able to be easily treated with local anesthetic.

Dermatomes in the thoracic region have been labeled with letter-number combinations that show how the region is connected in question and the sensory nerve that supplies the area. For example the C1 spinal nerve doesn’t have a dermatome. However, all spinal nerves in the region are labeled C1 – C8 and T9 is a reference to belly button. Dermatomes are layered vertically on the trunk while dermatomes on the extremities are typically in a longitudinal.

Dermatome Map

The dermatome map is one of the common features of textbooks that cover anatomy. However, the dermatome map is not consistent both within and inter-textbook. Its naming is inconsistent as are some textbooks that have different maps on various pages. This can be particularly challenging when the authors of different chapters disagree on the choice of dermatome map. Most textbooks use maps of Foerster, Keegan, and Garrett however, they do not provide appropriate references. In addition, four textbooks utilize maps with no citations, and one of them is one that refers to only secondary sources.

Dermatomes are the parts of the skin that receives sensory information from the dorsal root of a spinal nerve. The dermatomes are not uniformly found, but they tend to dip lower than horizontally. This is a natural variation and some tissue types are covered with more than one. Furthermore dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons in those limbs that are dorsal.
