Dermatomes And Myotomes Anatomy Geeky Medics – If you have ever wondered what the human dermatome map is, you’ve come to the right place. Before we get to an image, it’s important to talk about the definition of a dermatome. What are the various types? And, most importantly, why is it important to learn about dermatomes in order to know more about how the body works. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the spine. Dermatomes are important in allowing doctors to construct models of the cord, which are useful for diagnosis. Two maps are widely accepted by medical specialists. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are frequently used. The trigeminal and maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that are linked to a specific nerve. In cases of spinal injury, pain may be felt in a dermatome that is controlled by the 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, you should consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by only one spinal nerve. The nerves transmit sensory, motor and autonomic information. They form an element of the peripheral nerve system which connects brain and rest of the body. A dermatome may become affected due to a spinal cord lesion. When one of these dermatomes gets injured, it is able to be easily treated with an local anesthetic.
The dermatomes of the thoracic region are labeled by letter-number combinations, which show the connection between the region as well as the nerve which supplies that area. For instance the C1 spinal nerve doesn’t possess a dermatome, however the other spinal nerves are labeled as C1-C8 and T9 is a reference with the belly button. Dermatomes are laid horizontally on the trunk, and dermatomes located on the extremities tend to be in a longitudinal.
Dermatome Map
The dermatome map is a common feature of textbooks teaching anatomy. But, the map is inconsistency both within and inter-textbook. The name is not consistent and certain textbooks have different maps on different pages. This can be particularly challenging when the authors of different chapters are not unified in their choice of dermatome map. A majority of textbooks employ the Maps of Foerster, Keegan, and Garrett but do not include proper references. In addition, four textbooks utilize maps without citations, including one that uses only secondary sources.
Dermatomes are the regions of skin that receives sensory input from the dorsal branch of one spinal nerve. Dermatomes aren’t uniformly located, but they tend to dip more inferiorly than horizontally. This is a natural variation and some tissues have more than one. Furthermore dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons that originate from Dorsal limbs.
