Dermatomes Neurology Medbullets Step 1 – If you’ve ever thought about how the human dermatome map appears, then you’re at the right spot. Before we look at this map, lets take a look at what a dermatome is. What are the different types? The most important thing is why is it necessary to understand dermatomes in order to understand your body. Read on to find out more. You may 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 can help doctors to develop diagrams of the spine that aid in the diagnosis. Two major maps are accepted by medical specialists. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are commonly used. The trigeminal nerve , as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are skin areas that are attached to a particular nerve bundle. In the case of spinal cord injury, pain may be felt in a dermatome that is controlled by the nerve. The same is true for the pain caused by shingles outbreaks is felt by specific spinal nerves. If you experience a neurologic condition or pain that involves the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by only one spinal nerve. These nerves provide sensory, motor and autonomic information. They form a part of the peripheral nervous system, which connects brain and all the body. Dermatomes can get affected because of a spinal cord lesion. When one of these dermatomes gets injured, it is able to be treated easily with the use of a local anesthetic.
Dermatomes in the thoracic region are labeled with letter-number combinations that show the relationship between the area along with the sensor nerve that supplies that region. For instance the C1 spinal nerve doesn’t possess a dermatome, however others spinal nerves have been labeled C1 – C8 T9, which corresponds to belly button. Dermatomes are layered horizontally on the trunk, and dermatomes located on the extremities tend to be longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks teaching anatomy. But, the map is not uniform both inside and inter-textbook. The name is not consistent and some textbooks include different maps on various pages. This is particularly problematic in the event that the authors of various chapters disagree on the choice of dermatome map. Most textbooks use Maps of Foerster, Keegan, and Garrett however they don’t provide appropriate references. Additionally, four textbooks employ maps with no citations. This includes one that uses only secondary sources.
The dermatome is the area of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t uniformly located, but they tend to dip lower than horizontally. This is a normal variation and certain tissues are covered by more than one dermatome. Additionally dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons of the dorsal parts of the limbs.
