Cervical Spine Dermatome Map – If you’ve ever wondered how the human dermatome chart is, you’ve come to the right spot. Before we go to an image, it’s important to talk about what a dermatome is. What are the different kinds? The most important thing is what is the reason to be aware of dermatomes order to understand your body. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

Dermatomes Definition Chart And Diagram

What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes are important in allowing doctors to create models of the cord that aid in the diagnosis. Two major maps are regarded as valid by medical experts. These are: the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and remain frequently used. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.

Dermatomes are skin regions that are linked to a specific nerve bundle. In the case of spinal cord injury, pain may be experienced in a dermatome that is innervated by that nerve. The same is true for the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome region, you need to visit a doctor.

What are Some Examples of Dermatomes?

A dermatome is a segment of skin supplied by the spinal nerve. These nerves carry sensory, motor and autonomic information. They form an element of the peripheral nerve system which connects the brain with the all the body. A dermatome may become affected due to a spinal cord injury. When one of these dermatomes becomes injured, it could be easily treated using the use of a local anesthetic.

Dermatomes in the thoracic region have been labeled by letter-number combinations, which show how the region is connected along with the sensor nerve that is responsible for the area. For example C1 spinal nerve doesn’t possess a dermatome, however those spinal nerves that are labeled C1-C8 and T9 refers to belly button. Dermatomes are laid horizontally on the trunk and dermatomes located on the extremities tend to be longitudinal.

Dermatome Map

The dermatome map is the most common element in textbooks that teach anatomy. The dermatome map is inconsistent both intra and inter-textbook. Its name isn’t consistent and certain textbooks have different maps on various pages. This is particularly problematic when the authors of multiple chapters are not unified in their choice of dermatome map. Most textbooks use Maps of Foerster, Keegan, and Garrett however they don’t provide proper references. Additionally, four textbooks employ maps with no citations. This includes one that cites only secondary sources.

Dermatomes are the regions of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. The dermatomes are not uniformly located, but they tend to dip less inferiorly than horizontally. This is an inherent variation and certain tissues are covered by more than one dermatome. Also dorsal spinal nerve roots may contain intrathecal intersegmental connections with sensory neurons that originate from Dorsal limbs.
