Lumbar Dermatome Map – If you have ever wondered how the human dermatome map looks, you’ve come to the right place. Before we go to the map, let’s look at what is a dermatome. What are the different kinds? And, most importantly, what is the reason to understand dermatomes in order to know more about how the body works. Read on to find out more. You might 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 are important in allowing doctors to develop diagrams of the spine, which help in diagnosing. Two major maps are regarded as valid by medical specialists. There is the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and remain often used. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.

Dermatomes are areas of skin that connect to a particular nerve. In cases of spinal cord injuries, pain may be felt in a dermatome, which is connected to that nerve. The same is true for 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 region, you need to visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin supplied by only one spinal nerve. These nerves relay sensory, motor, and autonomic messages. They form part of the peripheral nerve system which connects the brain with the all the body. Dermatomes can become affected due to a spinal cord injury. If one of these dermatomes becomes injured, it could be easily treated using a local anesthetic.

The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate how the region is connected in question and the sensory nerve that serves this area. For example C1’s spinal nerve does not have a dematome, however those spinal nerves that are labeled C1 – C8 T9, which corresponds to the belly button. Dermatomes are laid vertically on the trunk those in the extremities are usually in a longitudinal.

Dermatome Map

The dermatome map is an integral part of textbooks that teach anatomy. However, the dermatome maps is not uniform both inside and inter-textbook. Its name isn’t consistent and some textbooks include distinct maps on different pages. This is particularly problematic when the authors of different chapters do not agree on the selection of dermatome map. Many textbooks use the maps of Foerster, Keegan, and Garrett but do not include proper references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that cites only secondary sources.

Dermatomes are the regions of skin that receives sensory innervation from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to be more inferior than horizontally. This is a natural variation and some tissues are covered by more than one dermatome. In addition to this dorsal spinal nerve roots may have intrathecal intersegmental anastomoses to sensory neurons in those limbs that are dorsal.
