Dermatomes Neurology Medbullets Step 1 – If you’ve ever thought about what the human dermatome map looks, you’ve come to the right place. Before we look at an image, it’s important to discuss what a dermatome is. What are the various types? Most importantly, why is it essential to understand dermatomes in order to understand our body.

What is a Dermatome?
“dermatome” or “dermatome” refers to a tissue that covers your spinal cord. Dermatomes play a crucial role in allowing doctors to create maps of the spinal cord, which can be useful in diagnosing. Two major maps are regarded as valid by medical experts. There is the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and remain often employed. The trigeminal nerve and the maxillary nerves are the two largest dermatomes.
Dermatomes are skin-like areas which are connected to a specific nerve. In cases of spinal injury, pain can be felt in a dermatome that is surrounded by the nerve. Similar to the pain that is caused by an outbreak of shingles is felt by specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is provided by the spinal nerve. The nerves transmit motor, sensory as well as autonomic information. They form a part of the peripheral nerve system which connects brain and all the body. Dermatomes can be affected by a spinal cord lesion. When one of these dermatomes is injured, it can be easily treated using an 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 which supplies that region. For instance C1 spinal nerve does not possess a dermatome, however others spinal nerves have been identified as C1-C8, while T9 corresponds to the belly button. Dermatomes are laid vertically on the trunk while dermatomes on the extremities tend to be long.
Dermatome Map
Dermatome maps are a common feature of textbooks that cover anatomy. The dermatome map is inconsistent both intra and inter-textbook. Its name isn’t consistent, and some textbooks feature different maps on various pages. This is particularly problematic when the authors of multiple chapters differ in their choice of dermatome map. A majority of textbooks employ the map of Foerster, Keegan, and Garrett but don’t include adequate references. In addition, four textbooks utilize maps with no citations, and one of them is one that refers to only secondary sources.
Dermatomes are the parts of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip less inferiorly than horizontally. This is an inherent variation and some tissues may be covered by multiple dermatomes. Also dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons of the dorsal limbs.
