Dermatomes Development Maps TeachMeAnatomy – If you have ever wondered what the human dermatome’s map looks, you’ve come to the right place. Before we move on to the map, let’s talk about the definition of a dermatome. What are the different kinds? And, most importantly, why is it important to be aware of dermatomes order to comprehend our body. Read on to find out more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes play a crucial role in allowing doctors to create diagrams of the spine that are useful for diagnosis. Two major maps are accepted by medical specialists. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s, and are widely employed. The trigeminal and maxillary nerve are the biggest dermatomes.
Dermatomes are skin regions that are attached to a specific nerve. When there is a spinal cord injuries, pain may be felt in a dermatome which is controlled by the nerve. Similarly, the pain caused by shingles outbreaks can be felt in particular 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?
A dermatome is a segment of skin that is provided by the spinal nerve. These nerves carry sensory, motor, as well as autonomic information. They form part of the peripheral nervous system which connects the brain and all the body. Dermatomes can get affected because of a spinal injury. If one of these dermatomes is injured, it can be easily treated using a local anesthetic.
Dermatomes in the thoracic region are identified using letter-number sequences that demonstrate the connection between the area along with the sensor nerve which supplies that region. For instance, the C1 spinal nerve does not possess a dermatome, however those spinal nerves that are labeled C1-C8 and T9 is a reference with the belly button. Dermatomes are layered horizontally on the trunk those on the extremities are typically longitudinal.
Dermatome Map
The dermatome map is an integral part of textbooks that teach anatomy. However, the dermatome maps is inconsistency both within and inter-textbook. Its name isn’t consistent, and some textbooks feature various maps on different pages. This can be particularly challenging when the authors of several chapters are not unified in their choice of dermatome map. The majority of textbooks utilize the map of Foerster, Keegan, and Garrett however they don’t provide proper references. In addition, four textbooks utilize maps with no citations. This includes one that refers to only secondary sources.
Dermatomes are the parts of skin that receives sensory input from the dorsal root of one spinal nerve. Dermatomes aren’t evenly placed, however they tend to dip more inferiorly than horizontally. This is an inherent variation and some tissue types are covered with more than one. In addition to this dorsal spinal nerve roots may have intrathecal intersegmental anastomoses with sensory neurons of the dorsal limbs.
