What are the various kinds? And most importantly, why is it essential to be aware of dermatomes order to better understand our body. 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 spine. Dermatomes can help doctors to develop maps of the spinal cord that are useful for diagnosis. Two major maps are regarded as valid by medical professionals. These are: the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s, and are widely used. The trigeminal nerve and the maxillary nerve are the largest dermatomes.

Dermatomes are skin regions that connect to a particular nerve. In cases of spinal injury, pain can be felt in a dermatome, which is connected to that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt on specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are segments of skin supplied by the spinal nerve. These nerves carry sensory, motor, as well as autonomic information. They form a part of the peripheral nerve system, which connects the brain with the all the body. A dermatome may get affected because of a spinal cord injury. If one of these becomes injured, it can be easily treated with local anesthetic.

Dermatomes in the thoracic region are identified by letter-number combinations, which show the connection between the region in question and the sensory nerve that serves that region. For instance the C1 spinal nerve doesn’t possess a dermatome, however those spinal nerves that are labeled C1-C8 T9, which corresponds to the belly button. Dermatomes are layered in horizontally on the trunk, those on the extremities tend to be in a longitudinal.

Dermatome Map

The dermatome map is an integral part of textbooks that teach anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. The names are inconsistent and some textbooks include different maps on various pages. This can be particularly challenging in the event that the authors of various chapters do not agree on the selection of dermatome map. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett however, they do not provide the proper references. Moreover, four textbooks use maps with no citations. This includes one that refers to only secondary sources.

Dermatomes are the parts of skin that receives sensory stimulation from the dorsal branch of one spinal nerve. Dermatomes aren’t evenly located, but they tend to be more inferior than horizontally. This is an inherent variation and certain tissues have more than one. Also, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons in Dorsal limbs.
