Dermatome Map Of Head By Annie Campbell Medical Tech Campbell – If you’ve ever wanted to know what the human dermatome map looks, you’ve come to the right spot. Before we get to this map, lets take a look at the definition of a dermatome. What are the various types? The most important thing is why is it important to learn about dermatomes in order to understand your 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 covers the spinal cord. Dermatomes play a crucial role in allowing doctors to construct models of the cord that help in diagnosing. Two maps are widely accepted 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 as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are skin-like areas that are attached to a particular nerve bundle. In cases of spinal injuries, pain may be felt in a dermatome, which is surrounded by the nerve. The same is true for the pain caused by an outbreak of shingles is felt by specific spinal nerves. If you are experiencing pain or neurological condition involving 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 carry sensory, motor, and autonomic information. They form part of the peripheral nervous system, which connects brain and all the body. Dermatomes can become affected due to a spinal injury. If one of these dermatomes becomes injured, it can be easily treated with a local anesthetic.
Dermatomes in the thoracic area are marked with letter-number combinations that show the connection between the area and the sensory nerve that is responsible for that area. For instance, the C1 spinal nerve does not possess a dermatome, however those spinal nerves that are labeled C1-C8 and T9 refers to belly button. Dermatomes are layered horizontally along the trunk, however, dermatomes that are located on the extremities are generally linear.
Dermatome Map
The dermatome map is an integral part of textbooks that teach anatomy. However, the dermatome map is not consistent both within and inter-textbook. The name is not consistent and certain textbooks have distinct maps on different pages. This is especially problematic in the event that the authors of various chapters are not unified in their choice of dermatome map. Many textbooks use the Maps of Foerster, Keegan, and Garrett however, they do not provide adequate references. Furthermore, four textbooks make use of maps that do not have citations, such as one that uses only secondary sources.
The dermatome is the area of skin that receives sensory stimulation from the dorsal roots of one spinal nerve. The dermatomes are not uniformly placed, however they tend to dip lower than horizontally. This is a natural variation, and some tissues may be covered by multiple dermatomes. Additionally dorsal spinal rootlets could have intrathecal intersegmental anastomoses to sensory neurons that originate from the dorsal parts of the limbs.
