Dermatomes Neurology Medbullets Step 1 – If you’ve ever wondered how the human dermatome chart looks, you’ve come to the right spot. Before we look at this map, lets look at what a dermatome is. What are the different types? Most importantly, why is it essential to be aware of dermatomes order to comprehend our body. 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 your spinal cord. Dermatomes can help doctors to create models of the cord that are useful for diagnosis. Two maps are widely accepted by medical professionals. 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 among the most extensive dermatomes.
Dermatomes are skin regions that are attached to a particular nerve. When there is a spinal cord injuries, pain may be felt in a dermatome which is surrounded by the nerve. The same is true for the pain caused by shingles outbreaks can be felt on specific spinal nerves. If you feel nerve pain or neurological problem affecting the dermatome, it is recommended that you visit a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is supplied by the spinal nerve. These nerves relay sensory, motor, and autonomic messages. They form a part of the peripheral nerve system, which connects the brain and rest of the body. Dermatomes can get affected because of a spinal injury. If one of these is injured, it can be easily treated with a local anesthetic.
The dermatomes of the thoracic region are identified using letter-number sequences that demonstrate the connection between the region and the sensory nerve that supplies that region. For instance, the C1 spinal nerve does not have a dermatome, but others spinal nerves have been labeled C1 – C8, while T9 corresponds to the belly button. Dermatomes are layered in vertically on the trunk however, dermatomes on the extremities are typically longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks that cover anatomy. The dermatome map is inconsistent both intra and inter-textbook. The name is not consistent as are some textbooks that have various maps on different pages. This is especially problematic when the authors of multiple chapters are not unified in their choice of dermatome maps. A majority of textbooks employ the Maps of Foerster, Keegan, and Garrett but don’t include the proper references. Moreover, four textbooks use maps with no citations, and one of them is one that refers to only secondary sources.
Dermatomes are the parts of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly located, but they tend to dip lower than horizontally. This is a natural variation and some tissues are covered by more than one dermatome. Additionally dorsal spinal rootlets could have intrathecal intersegmental anastomoses with sensory neurons of Dorsal limbs.
