Lumbar Disc Herniation – If you have ever wondered what the human dermatome’s map is, you’ve come to the right place. Before we move on to this map, lets talk about what a dermatome is. What are the different kinds? And most importantly, what is the reason to understand dermatomes in order to comprehend your body. Continue reading to learn more. You might be surprised!

What is a Dermatome?
” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes are important in allowing physicians to build models of the cord that help in diagnosing. Two maps are widely accepted by medical specialists. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are frequently used. The trigeminal nerve , as well as the maxillary nerve are the largest dermatomes.
Dermatomes are skin areas which are connected to a particular nerve. In the case of spinal cord injury, pain may be felt in a dermatome, which is innervated by that nerve. The same is true for the pain caused by an outbreak of shingles can be felt on specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are the segments of skin that is supplied by only one spinal nerve. The nerves transmit motor, sensory, and autonomic information. They form part of the peripheral nervous system which connects brain and all the body. Dermatomes can get affected because of a spinal cord lesion. If one of these is injured, it can be treated easily with an local anesthetic.
Dermatomes in the thoracic region are labeled with letters-numbers that illustrate the relationship between the area as well as the nerve that is responsible for the area. For example the C1 spinal nerve doesn’t have a dermatome, but all spinal nerves in the region are labeled C1 – C8 and T9 is a reference with the belly button. Dermatomes are layered in vertically on the trunk and dermatomes located in the extremities are usually in a longitudinal.
Dermatome Map
Dermatome maps are an integral part of textbooks teaching anatomy. But, the map is not consistent both within and inter-textbook. Its naming is inconsistent and some textbooks include distinct maps on different pages. This is particularly problematic in the event that the authors of various chapters are not unified in their choice of dermatome maps. The majority of textbooks utilize the map of Foerster, Keegan, and Garrett but don’t include the proper references. Additionally, four textbooks employ maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the regions of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly placed, however they tend to dip less inferiorly than horizontally. This is a natural variation and some tissues have more than one. In addition to this dorsal spinal rootlets could contain intrathecal intersegmental connections with sensory neurons from those limbs that are dorsal.
