Dermatome Map Chest – If you’ve ever thought about how the human dermatome chart will look, you’re in the right spot. Before we get to our map, we’ll take a look at what is a dermatome. What are the various types? Most importantly, why is it important to know about dermatomes in order to better understand how the body works. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes play a crucial role in allowing physicians to build images of spinal cord that help in diagnosing. Two major maps are accepted by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still commonly employed. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.

Dermatomes are skin-like areas that are linked to a specific nerve bundle. In the case of spinal cord injury, pain can be experienced in a dermatome that is controlled by the nerve. In the same way, the pain triggered by an outbreak of shingles can be felt in specific spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome area, you must 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 relay sensory, motor, and autonomic information. 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 cord injury. If one of these dermatomes becomes injured, it could be easily treated with a local anesthetic.

The dermatomes of the thoracic region are labeled by letter-number combinations, which show the relationship between the area along with the sensor nerve that supplies the area. For instance, the C1 spinal nerve doesn’t have a dematome, however others spinal nerves have been identified as C1-C8, while T9 corresponds to belly button. Dermatomes are laid horizontally along the trunk, while dermatomes on the extremities are typically linear.

Dermatome Map

Dermatome maps are a common feature of textbooks teaching anatomy. The dermatome map is not uniform both inside and inter-textbook. Its name isn’t consistent as are some textbooks that have distinct maps on different pages. This can be particularly challenging when the authors of multiple chapters do not agree on the selection of dermatome maps. A majority of textbooks employ the map of Foerster, Keegan, and Garrett however they don’t provide adequate references. Additionally, four textbooks employ maps that do not have citations, such as one that refers to only secondary sources.

Dermatomes are the areas of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. The dermatomes are not uniformly found, but they tend to dip lower than horizontally. This is a natural variation, and some tissues are covered by more than one dermatome. Additionally dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons in the dorsal limbs.
