Evaluation And Goals – If you have ever wondered what the human dermatome map looks, you’ve come to the right spot. Before we go to the map, let’s take a look at the definition of a dermatome. What are the different types? Most importantly, why is it essential to understand dermatomes in order to comprehend how the body works. Read on to find out more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
“dermatome,” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes are important in allowing doctors to create images of spinal cord, which aid in the diagnosis. Two major maps are recognized by medical professionals. There is the Keegan and Garret map and the Foerster map. These maps were created in the 1930s, and are often employed. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.
Dermatomes are skin-like areas that connect to a specific nerve bundle. When there is a 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 is felt by specific spinal nerves. If you feel neurologic condition or pain that involves the dermatome region, you need to see a doctor.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin that is supplied by the spinal nerve. These nerves carry sensory, motor and autonomic messages. They form a part of the peripheral nervous system which connects brain and other parts of the body. A dermatome may get affected because of a spinal cord injury. If one of these dermatomes gets injured, it is able to be easily treated using an local anesthetic.
The dermatomes of the thoracic area are marked using letter-number sequences that demonstrate the relationship between the area along with the sensor nerve that is responsible for that area. For instance the C1 spinal nerve doesn’t have a dermatome, but all spinal nerves in the region are identified as C1-C8 and T9 refers to belly button. Dermatomes are layered horizontally on the trunk while dermatomes in the extremities are usually linear.
Dermatome Map
Dermatome maps are an integral part of textbooks teaching anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. The name is not consistent, and some textbooks feature different maps on various pages. This is especially problematic in the event that the authors of various chapters are not unified in their choice of dermatome map. A majority of textbooks employ the diagrams drawn by Foerster, Keegan, and Garrett but don’t include proper references. Additionally, four textbooks employ maps with no citations, and one of them is one that only cites secondary sources.
Dermatomes are the areas of skin that receives sensory innervation from the dorsal root of a spinal nerve. Dermatomes aren’t evenly found, but they tend to dip less inferiorly than horizontally. This is a natural variation and some tissue types are covered with more than one. Additionally dorsal spinal roots could have intrathecal intersegmental anastomoses to sensory neurons of the dorsal limbs.
