What are the different types? The most important thing is why is it essential to be aware of dermatomes order to comprehend how the body works. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help doctors to create images of spinal cord that can be useful in diagnosing. Two major maps are accepted by medical experts. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and remain widely employed. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.

Dermatomes are skin areas that are attached to a specific nerve bundle. In cases of spinal injury, pain may be experienced in a dermatome that is surrounded by the nerve. The same is true for the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you feel neurologic condition or pain that involves the dermatome, it is recommended that you visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin that is provided by the spinal nerve. The nerves transmit sensory, motor, and autonomic signals. They form a part of the peripheral nerve system, that connects the brain to the rest of the body. A dermatome may get affected because of a spinal injury. When one of these dermatomes becomes injured, it can be treated easily with the use of a local anesthetic.

The dermatomes of the thoracic region are labeled by letter-number combinations, which show the relationship between the area as well as the nerve that serves the area. For instance, the C1 spinal nerve doesn’t have a dermatome. However, others spinal nerves have been labeled C1-C8 and T9 is a reference to the belly button. Dermatomes are layered in vertically on the trunk those on the extremities tend to be longitudinal.

Dermatome Map

The dermatome map is one of the common features of textbooks that cover anatomy. But, the map is inconsistency both within and inter-textbook. Its name isn’t consistent as are some textbooks that have different maps on different pages. This is especially problematic when the authors of several chapters are not unified in their choice of dermatome maps. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide the proper references. Additionally, four textbooks employ maps that do not have citations, such as one that cites only secondary sources.

Dermatomes are the regions of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. Dermatomes aren’t always evenly situated, but they tend to dip more inferiorly than horizontally. This is a normal variation and certain tissue types are covered with more than one. Also dorsal spinal nerve roots may contain intrathecal intersegmental connections with sensory neurons of Dorsal limbs.
