Before we look at an image, it’s important to discuss what a dermatome actually is. What are the different kinds? And most importantly, what is the reason to know about dermatomes in order to know more about the human body. 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 play a crucial role in allowing doctors to develop images of spinal cord that are useful for diagnosis. Two major maps are regarded as valid by medical experts. These are: the Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are often utilized. The trigeminal nerve as well as the maxillary nerves are the two largest dermatomes.
Dermatomes are areas of skin that are linked to a specific nerve. In cases of spinal cord injuries, pain may be felt in a dermatome that is innervated by that nerve. The same is true for the pain caused by an outbreak of shingles can be felt in specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome, it is recommended that you consult with a physician.

What are Some Examples of Dermatomes?
Dermatomes are a part of skin supplied by the spinal nerve. The nerves transmit motor, sensory and autonomic signals. They form part of the peripheral nervous system which connects the brain and other parts of the body. A dermatome may get affected because of a spinal lesion. If one of these dermatomes becomes injured, it could be easily treated using the use of a local anesthetic.
The dermatomes of the thoracic region are labeled using letter-number sequences that demonstrate the connection between the area along with the sensor nerve that is responsible for this area. For instance the C1 spinal nerve doesn’t have a dermatome. However, those spinal nerves that are labeled C1 – C8 and T9 is a reference to the belly button. Dermatomes are layered vertically on the trunk however, dermatomes in the extremities are usually linear.
Dermatome Map
Dermatome maps are the most common element in textbooks that teach anatomy. However, the dermatome map is not uniform both inside and inter-textbook. Its naming is inconsistent as are some textbooks that have distinct maps on different pages. This can be particularly challenging when the authors of several chapters are not unified in their choice of dermatome map. Most textbooks use maps of Foerster, Keegan, and Garrett but do not include appropriate references. In addition, four textbooks utilize maps with no citations, and one of them is one that only cites secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal root of a spinal nerve. Dermatomes aren’t evenly found, but they tend to be more inferior than horizontally. This is a natural variation and certain tissue types are covered with more than one. Furthermore, dorsal spinal rootlets may contain intrathecal intersegmental connections with sensory neurons from those limbs that are dorsal.
