Leg Dermatomes – If you’ve ever thought about what the human dermatome’s map will look, you’re in the right spot. Before we move on to this map, lets talk about what a dermatome actually is. What are the different types? The most important thing is why is it important to understand dermatomes in order to understand how the body works. Continue reading to learn 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 your spinal cord. Dermatomes help physicians to build maps of the spinal cord that help in diagnosing. Two major maps are regarded as valid by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are widely used. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin areas that are attached to a specific nerve bundle. When there is a spinal cord injury, pain may be felt in a dermatome that is controlled by the nerve. Similarly, the pain caused by an outbreak of shingles is felt by specific spinal nerves. If you suffer from nerve pain or neurological problem affecting the dermatome, you should see a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin supplied by a single spinal nerve. These nerves relay sensory, motor, and autonomic information. They form part of the peripheral nervous system which connects the brain and all the body. A dermatome may become affected due to a spinal lesion. When one of these dermatomes becomes injured, it can be easily treated using the use of a local anesthetic.
The dermatomes of the thoracic area are marked using letter-number sequences that demonstrate how the region is connected along with the sensor nerve that serves that area. For instance C1’s spinal nerve does not have a dematome, however the other spinal nerves are labeled C1-C8 and T9 refers with the belly button. Dermatomes are layered vertically on the trunk while dermatomes on the extremities are typically long.
Dermatome Map
Dermatome maps are an integral part of textbooks that teach anatomy. But, the map is not uniform both inside and inter-textbook. Its naming is inconsistent and certain textbooks have distinct maps on different pages. This can be particularly challenging when the authors of different chapters do not agree on the selection of dermatome map. A majority of textbooks employ the maps of Foerster, Keegan, and Garrett however they don’t provide appropriate references. Additionally, four textbooks employ maps with no citations. This includes one that uses only secondary sources.
The dermatome is the area of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly located, but they tend to dip lower than horizontally. This is a natural variation and some tissues have more than one. Furthermore, dorsal spinal rootlets may have intrathecal intersegmental anastomoses to sensory neurons that originate from the dorsal parts of the limbs.
