Anatomy Dermatomes Of The Face Image – If you’ve ever thought about how the human dermatome map is, you’ve come to the right place. Before we move on to an image, it’s important to look at what a dermatome is. What are the various kinds? And most importantly, why is it essential to learn about dermatomes in 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 covers the cord of the spinal. Dermatomes play a crucial role in allowing physicians to build models of the cord that are useful for diagnosis. Two maps are widely accepted by medical professionals. There is the Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are widely used. The trigeminal nerve as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are skin-like areas which are connected to a specific nerve bundle. In cases of spinal cord injury, pain may be felt in a dermatome which is connected to that nerve. Similar to the pain that is caused by shingles outbreaks can be felt in specific spinal nerves. If you experience a nerve pain or neurological problem affecting the dermatome area, you must consult a physician.

What are Some Examples of Dermatomes?
A dermatome is a segment of skin supplied by only one spinal nerve. The nerves transmit motor, sensory, and autonomic signals. They form part of the peripheral nervous system which connects the brain and rest of the body. A dermatome may suffer from a spinal cord injury. When one of these dermatomes becomes injured, it could be treated easily with an local anesthetic.
The dermatomes of the thoracic region are identified by letter-number combinations, which show the connection between the region and the sensory nerve that supplies the area. For example C1 spinal nerve does not possess a dermatome, however the other spinal nerves are labeled C1 – C8 and T9 refers to belly button. Dermatomes are layered in horizontally 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. However, the dermatome maps is inconsistency both within and inter-textbook. Its name isn’t consistent and certain textbooks have different maps on different pages. This can be particularly challenging when the authors of multiple chapters differ in their choice of dermatome maps. Most textbooks use map of Foerster, Keegan, and Garrett however they don’t provide proper references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that refers to only secondary sources.
Dermatomes are the regions of the skin that receives sensory information from the dorsal root of a spinal nerve. The dermatomes are not uniformly found, but they tend to dip more inferiorly than horizontally. This is a natural variation and certain tissues are covered by more than one dermatome. Also dorsal spinal nerve roots may contain intrathecal intersegmental connections with sensory neurons in the dorsal limbs.
