Back Dermatome Map – If you’ve ever thought about what the human dermatome map will look, you’re in the right place. Before we go to this map, lets look at what a dermatome actually is. What are the different types? And, most importantly, why is it essential 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?

The term “dermatome” refers to a tissue that covers your spinal cord. Dermatomes help doctors to construct models of the cord, which can be useful in diagnosing. Two major maps are regarded as valid by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are commonly used. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.

Dermatomes are skin regions which are connected to a particular nerve. In cases of spinal cord injury, pain can be felt in a dermatome which is surrounded by the nerve. Similar to the pain that is caused by shingles outbreaks is felt by specific spinal nerves. If you are experiencing discomfort or neurological issue involving the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are segments of skin supplied by one spinal nerve. These nerves provide motor, sensory and autonomic messages. They form an element of the peripheral nervous system that connects the brain to the rest of the body. Dermatomes can become affected due to a spinal cord lesion. If 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 by letter-number combinations, which show the connection between the area as well as the nerve that supplies that region. For example C1’s spinal nerve doesn’t have a dematome, however others spinal nerves have been labeled C1-C8, while T9 corresponds to the belly button. Dermatomes are layered in horizontally along the trunk, those on the extremities are typically linear.

Dermatome Map

Dermatome maps are the most common element in textbooks teaching anatomy. However, the dermatome maps is not uniform both inside and inter-textbook. Its name isn’t consistent and certain textbooks have different maps on various pages. This is especially problematic when the authors of several chapters are not unified in their choice of dermatome map. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett however, they do not provide the proper references. In addition, four textbooks utilize maps with no citations. This includes one that cites only secondary sources.

Dermatomes are the areas of skin that receives sensory innervation from the dorsal root of one spinal nerve. The dermatomes are not uniformly situated, but they tend to dip more inferiorly than horizontally. This is a natural variation and some tissues may be covered by multiple dermatomes. Additionally dorsal spinal nerve roots may be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal limbs.
