Dermatomes Of Lower Limb Great Toe L4 Reflexology Physical – If you have ever wondered how the human dermatome chart looks, you’ve come to the right place. Before we get to an image, it’s important to talk about what is a dermatome. What are the different kinds? And, most importantly, what is the reason to know about dermatomes in order to know more about the human body. Continue reading to learn more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers the spinal cord. Dermatomes can help doctors to construct maps of the spinal cord, which aid in the diagnosis. Two major maps are regarded as valid by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are often employed. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are areas of skin that are linked to a specific nerve bundle. In cases of spinal injury, pain can be felt in a dermatome, which is controlled by the nerve. Similar to the pain that is caused by shingles outbreaks can be felt on specific spinal nerves. If you suffer from nerve pain or neurological problem affecting the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is provided by one spinal nerve. These nerves relay sensory, motor, and autonomic signals. They form a part of the peripheral nerve system, that connects the brain to the other parts of the body. Dermatomes can become affected due to a spinal injury. If one of these dermatomes becomes injured, it can be easily treated with the use of a local anesthetic.
Dermatomes in the thoracic region are identified using letter-number sequences that demonstrate how the region is connected and the sensory nerve that is responsible for the area. For example the C1 spinal nerve doesn’t have a dermatome. However, others spinal nerves have been labeled C1 – C8 and T9 refers to the belly button. Dermatomes are laid horizontally on the trunk those on the extremities tend to be linear.
Dermatome Map
Dermatome maps are a common feature of textbooks that cover anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. Its name isn’t consistent as are some textbooks that have different maps on various pages. This is particularly problematic in the event that the authors of various chapters differ in their choice of dermatome map. Most textbooks use maps of Foerster, Keegan, and Garrett however they don’t provide proper references. Additionally, four textbooks employ maps with no citations, and one of them is one that refers to only secondary sources.
Dermatomes are the regions of skin that receives sensory innervation from the dorsal branch of one spinal nerve. The dermatomes are not uniformly placed, however they tend to be more inferior than horizontally. This is an inherent variation and some tissue types are covered with more than one. In addition to this dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons from Dorsal limbs.
