Before we go to our map, we’ll discuss the definition of a dermatome. What are the different types? The most important thing is what is the reason to be aware of dermatomes order to know more about the human body. Read on to find out more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the spine. Dermatomes help doctors to construct images of spinal cord, which aid in the diagnosis. Two maps are widely accepted by medical specialists. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are commonly used. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.
Dermatomes are areas of skin that connect to a particular nerve. In cases of spinal cord injury, pain may be felt in a dermatome which is innervated by that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in specific spinal nerves. If you feel discomfort or neurological issue involving the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin that is supplied by a single spinal nerve. The nerves transmit motor, sensory and autonomic messages. They form a part of the peripheral nervous system which connects the brain with the other parts of the body. A dermatome may become affected due to a spinal injury. If one of these dermatomes is injured, it can be easily treated with local anesthetic.
Dermatomes in the thoracic region are identified using letter-number sequences that demonstrate the connection between the region in question and the sensory nerve that supplies that area. For instance C1’s spinal nerve doesn’t have a dermatome. However, others spinal nerves have been identified as C1-C8, while T9 corresponds to belly button. Dermatomes are layered in horizontally on the trunk, however, dermatomes that are located on the extremities are generally linear.
Dermatome Map
The dermatome map is a common feature of textbooks teaching anatomy. However, the dermatome maps is not uniform both inside and inter-textbook. Its naming is inconsistent and certain textbooks have different maps on different pages. This is particularly problematic when the authors of multiple chapters do not agree on the selection of dermatome map. The majority of textbooks utilize the map of Foerster, Keegan, and Garrett but do not include the proper references. Moreover, four textbooks use maps with no citations. This includes one that refers to only secondary sources.
Dermatomes are the areas of skin that receives sensory innervation from the dorsal branch of one spinal nerve. The dermatomes are not uniformly located, but they tend to dip less inferiorly than horizontally. This is a normal variation and certain tissues are covered by more than one dermatome. Also dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons that originate from the dorsal limbs.
