Cervical Dermatome Map Physical Therapy Massage Therapy Hand Therapy – If you’ve ever wondered how the human dermatome chart will look, you’re in the right place. Before we look at our map, we’ll discuss what a dermatome actually is. What are the various types? The most important thing is why is it important to learn about dermatomes in order to know more about how the body works. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the spinal cord. Dermatomes help doctors to develop diagrams of the spine, which can be useful 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 often employed. The trigeminal nerve , as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are skin regions that are linked to a specific nerve bundle. In the case of spinal cord injury, pain can be felt in a dermatome which is connected to that nerve. In the same way, the pain triggered by an outbreak of shingles is felt by specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome area, you must see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by only one spinal nerve. The nerves transmit sensory, motor and autonomic signals. They form an element of the peripheral nerve system, which connects the brain with the rest of the body. A dermatome may become affected due to a spinal cord injury. When one of these dermatomes is injured, it can be easily treated using the use of a local anesthetic.
Dermatomes in the thoracic region are labeled using letter-number sequences that demonstrate the connection between the area in question and the sensory nerve which supplies that region. For instance C1 spinal nerve doesn’t have a dematome, however those spinal nerves that are identified as C1-C8, while T9 corresponds to the belly button. Dermatomes are laid horizontally on the trunk, those in the extremities are usually in a longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks that cover anatomy. However, the dermatome maps is not consistent both within and inter-textbook. The names are inconsistent and certain textbooks have different maps on various pages. This is especially problematic when the authors of several chapters disagree on the choice of dermatome maps. The majority of textbooks utilize the maps of Foerster, Keegan, and Garrett however they don’t provide proper references. Additionally, four textbooks employ maps that do not have citations, such as one that only cites secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly situated, but they tend to dip lower than horizontally. This is an inherent variation and some tissue types are covered with more than one. Also dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons in the dorsal parts of the limbs.
