Dermatomes Development Maps TeachMeAnatomy – If you’ve ever thought about what the human dermatome map is, you’ve come to the right place. Before we get to this map, lets discuss the definition of a dermatome. What are the different kinds? Most importantly, why is it essential to understand dermatomes in order to know more about the human body. Continue reading to learn more. You might 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 physicians to build images of spinal cord, which aid in the diagnosis. Two maps are widely accepted by medical specialists. The Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are still commonly employed. The trigeminal nerve and the maxillary nerve are the biggest dermatomes.
Dermatomes are skin areas which are connected to a particular nerve bundle. In the case of spinal cord injuries, pain may be felt in a dermatome, which is surrounded by the nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in particular spinal nerves. If you are experiencing nerve pain or neurological problem affecting the dermatome, it is recommended that you consult a physician.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is supplied by a single spinal nerve. These nerves provide motor, sensory and autonomic information. They form a part of the peripheral nervous system which connects brain and other parts of the body. Dermatomes can suffer from a spinal lesion. If one of these dermatomes becomes injured, it could be easily treated with a local anesthetic.
The dermatomes of the thoracic region are identified using letter-number sequences that demonstrate the relationship between the area as well as the nerve that serves the area. For instance the C1 spinal nerve doesn’t possess a dermatome, however all spinal nerves in the region are labeled as C1-C8 and T9 refers to belly button. Dermatomes are laid horizontally along the trunk, however, dermatomes on the extremities tend to be in a longitudinal.
Dermatome Map
Dermatome maps are an integral part of textbooks that teach anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. The names are inconsistent and some textbooks include different maps on different pages. This is particularly problematic when the authors of several chapters do not agree on the selection of dermatome maps. Most textbooks use diagrams drawn by Foerster, Keegan, and Garrett but don’t include adequate references. Furthermore, four textbooks make use of maps with no citations, and one of them is one that cites only secondary sources.
Dermatomes are the areas of skin that receives sensory innervation from the dorsal root of one spinal nerve. Dermatomes aren’t uniformly found, but they tend to be more inferior than horizontally. This is a natural variation, and some tissues may be covered by multiple dermatomes. Additionally dorsal spinal roots could be anastomosed with intrathecal intersegmental sensory neurons in Dorsal limbs.
