What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes play a crucial role in allowing doctors to develop images of spinal cord that aid in the diagnosis. Two major maps are accepted by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are frequently used. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.

Dermatomes are skin-like areas that are attached to a particular nerve. When there is a spinal cord injury, pain may be felt in a dermatome, which is controlled by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt in specific spinal nerves. If you are experiencing pain or neurological condition involving the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin supplied by a single spinal nerve. These nerves relay sensory, motor, as well as autonomic information. They form a part of the peripheral nervous system which connects the brain with the other parts of the body. A dermatome may get affected because of a spinal lesion. When one of these dermatomes gets injured, it is able to be easily treated with local anesthetic.

The dermatomes of the thoracic region are identified using letter-number sequences that demonstrate the relationship between the area along with the sensor nerve that supplies that area. For instance C1’s spinal nerve does not have a dermatome. However, all spinal nerves in the region are labeled as C1-C8 and T9 is a reference to the belly button. Dermatomes are laid vertically on the trunk however, dermatomes that are located on the extremities are generally linear.

The dermatome map is a common feature of textbooks that cover anatomy. The dermatome map is not uniform both inside and inter-textbook. Its naming is inconsistent and some textbooks include different maps on different pages. This can be particularly challenging when the authors of several chapters are not unified in their choice of dermatome map. Many textbooks use the Maps of Foerster, Keegan, and Garrett however, they do not provide proper references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that cites only secondary sources.

The dermatome is the area of skin that receives sensory innervation from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip less inferiorly than horizontally. This is a normal variation and certain tissues may be covered by multiple dermatomes. Additionally dorsal spinal rootlets could have intrathecal intersegmental anastomoses to sensory neurons from the dorsal limbs.
