What are the different kinds? And, most importantly, why is it essential to understand dermatomes in order to comprehend our body. Read on to find out more. You might be surprised!

What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes help doctors to create models of the cord that aid in the diagnosis. Two major maps are regarded as valid by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are commonly used. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.

Dermatomes are skin-like areas that are linked to a specific nerve. When there is a spinal cord injury, pain can be felt in a dermatome which is innervated by that nerve. The same is true for the pain caused by shingles outbreaks is felt by specific spinal nerves. If you experience a pain or neurological condition involving the dermatome, you should consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is supplied by the spinal nerve. These nerves provide motor, sensory, and autonomic messages. They form an element of the peripheral nervous system, which connects the brain with the all the body. Dermatomes can become affected due to a spinal cord injury. If one of these becomes injured, it could be easily treated using local anesthetic.

Dermatomes in the thoracic area are marked by letter-number combinations, which show the relationship between the area as well as the nerve that is responsible for that region. For example, the C1 spinal nerve does not have a dermatome. However, those spinal nerves that are identified as C1-C8 and T9 refers with the belly button. Dermatomes are layered in vertically on the trunk however, dermatomes in the extremities are usually long.

Dermatome Map

The dermatome map is one of the common features of textbooks that cover anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. Its naming is inconsistent and certain textbooks have various maps on different pages. This is especially problematic when the authors of several chapters differ in their choice of dermatome map. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett however, they do not provide appropriate references. Moreover, four textbooks use maps that do not have citations, such as one that only cites secondary sources.

Dermatomes are the regions of the skin that receives sensory information from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly found, but they tend to dip more inferiorly than horizontally. This is a natural variation and certain tissues have more than one. Also, dorsal spinal rootlets may have intrathecal intersegmental anastomoses with sensory neurons in those limbs that are dorsal.
