Dermatomes Neurology Medbullets Step 1 – If you’ve ever wanted to know what the human dermatome map appears, then you’re at the right place. Before we move on to our map, we’ll talk about what a dermatome actually is. What are the various kinds? The most important thing is why is it essential to learn about dermatomes in order to better understand our body. Read on to find out 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 cord of the spinal. Dermatomes are important in allowing physicians to build maps of the spinal cord that are useful for diagnosis. Two major maps are recognized by medical experts. There is the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are widely utilized. The trigeminal nerve and the maxillary nerve are the largest dermatomes.
Dermatomes are skin-like areas which are connected to a particular nerve. In cases of spinal cord injury, pain may be experienced in a dermatome that is surrounded by the nerve. Similarly, the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you feel nerve pain or neurological problem affecting the dermatome area, you must visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is supplied by a single spinal nerve. The nerves transmit motor, sensory and autonomic signals. They form a part of the peripheral nerve system which connects the brain with the rest of the body. Dermatomes can suffer from a spinal cord injury. When one of these dermatomes becomes injured, it can be treated easily with an local anesthetic.
Dermatomes in the thoracic area are marked by letter-number combinations, which show the connection between the region in question and the sensory nerve that serves the area. For example C1 spinal nerve doesn’t have a dematome, however the other spinal nerves are identified as C1-C8, while T9 corresponds to belly button. Dermatomes are laid horizontally on the trunk however, dermatomes in the extremities are usually in a longitudinal.
Dermatome Map
The dermatome map is an integral part of textbooks teaching anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. The names are inconsistent, and some textbooks feature different maps on various pages. This is especially problematic when the authors of several chapters disagree on the choice of dermatome map. The majority of textbooks utilize the Maps of Foerster, Keegan, and Garrett however they don’t provide proper references. Moreover, four textbooks use maps with no citations, and one of them is one that refers to only secondary sources.
The dermatome is the area of the skin that receives sensory information from the dorsal branch of one spinal nerve. Dermatomes aren’t uniformly located, but they tend to dip less inferiorly than horizontally. This is a natural variation, and some tissues may be covered by multiple dermatomes. Additionally dorsal spinal rootlets could contain intrathecal intersegmental connections with sensory neurons from those limbs that are dorsal.
