Dermatome Chart Map Poster – If you’ve ever wondered what the human dermatome’s map appears, then you’re at the right place. Before we get to an image, it’s important to take a look at what is a dermatome. What are the various kinds? Most importantly, why is it essential to know about dermatomes in order to understand our body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes are important in allowing doctors to develop models of the cord that help in diagnosing. Two major maps are accepted by medical professionals. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still frequently used. The trigeminal nerve and the maxillary nerve are among the most extensive dermatomes.

Dermatomes are skin regions that are linked to a particular nerve. In cases of spinal cord injuries, pain may be felt 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 suffer from discomfort or neurological issue involving the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is supplied by the spinal nerve. The nerves transmit sensory, motor, and autonomic messages. They form a part of the peripheral nerve system which connects the brain and rest of the body. A dermatome may get affected because of a spinal cord injury. If one of these is injured, it can be easily treated with an local anesthetic.

Dermatomes in the thoracic region are identified with letter-number combinations that show how the region is connected as well as the nerve that serves that region. For example the C1 spinal nerve doesn’t have a dermatome. However, all spinal nerves in the region are labeled C1 – C8, while T9 corresponds with the belly button. Dermatomes are layered horizontally on the trunk, while dermatomes on the extremities tend to be linear.

Dermatome Map

Dermatome maps are one of the common features of textbooks teaching anatomy. But, the map is inconsistency both within and inter-textbook. Its naming is inconsistent, and some textbooks feature various maps on different pages. This can be particularly challenging when the authors of multiple chapters are not unified in their choice of dermatome maps. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett however, they do not provide the proper references. Additionally, four textbooks employ maps without citations, including one that refers to only secondary sources.

Dermatomes are the regions of skin that receives sensory stimulation from the dorsal root of one spinal nerve. Dermatomes aren’t evenly situated, but they tend to be more inferior than horizontally. This is a natural variation, and certain tissue types are covered with more than one. In addition to this dorsal spinal rootlets could contain intrathecal intersegmental connections with sensory neurons from Dorsal limbs.
