Pin On DERMATOMES – If you’ve ever wondered what the human dermatome map appears, then you’re at the right spot. Before we look at this map, lets look at what a dermatome is. What are the various types? Most importantly, why is it necessary to know about dermatomes in order to better understand your 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 are important in allowing doctors to develop diagrams of the spine, which help in diagnosing. Two major maps are accepted by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are commonly used. The trigeminal and maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin areas that are attached to a specific nerve bundle. In cases of spinal injury, pain can be felt in a dermatome, which is innervated by that nerve. Similarly, the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you suffer from discomfort or neurological issue involving the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by the spinal nerve. These nerves provide sensory, motor, and autonomic signals. They form an element of the peripheral nerve system that connects the brain to the rest of the body. A dermatome may become affected due to a spinal cord injury. If one of these dermatomes is injured, it can be easily treated with the use of a local anesthetic.
The dermatomes of the thoracic region are identified using letter-number sequences that demonstrate how the region is connected and the sensory nerve which supplies the area. For example the C1 spinal nerve doesn’t have a dematome, however all spinal nerves in the region are identified as C1-C8 T9, which corresponds to the belly button. Dermatomes are laid horizontally on the trunk while dermatomes on the extremities are typically longitudinal.
Dermatome Map
Dermatome maps are a common feature of textbooks that cover anatomy. The dermatome map is inconsistency both within and inter-textbook. The name is not consistent and certain textbooks have distinct maps on different pages. This can be particularly challenging in the event that the authors of various chapters disagree on the choice of dermatome map. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett but don’t include appropriate references. Moreover, four textbooks use maps without citations, including one that refers to only secondary sources.
Dermatomes are the regions of the skin that receives sensory information from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip less inferiorly than horizontally. This is an inherent variation and some tissues are covered by more than one dermatome. Furthermore dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons that originate from those limbs that are dorsal.
