Foerster Dermatome Map – If you have ever wondered how the human dermatome chart is, you’ve come to the right place. Before we go to our map, we’ll talk about what is a dermatome. What are the various types? And most importantly, why is it important to learn about dermatomes in order to better understand how the body works. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the spine. Dermatomes are important in allowing doctors to develop maps of the spinal cord that are useful for diagnosis. Two maps are widely accepted by medical specialists. They are the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and are widely utilized. The trigeminal nerve as well as the maxillary nerve are among the most extensive dermatomes.

Dermatomes are skin areas that connect to a specific nerve. When there is a spinal cord injuries, pain may be felt in a dermatome which is innervated by that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt on specific spinal nerves. If you experience a discomfort or neurological issue involving the dermatome, you should consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are segments of skin that is supplied by a single spinal nerve. These nerves carry motor, sensory, as well as autonomic information. They form a part of the peripheral nerve system, that connects the brain to the rest of the body. Dermatomes can get affected because of a spinal injury. If one of these is injured, it can be easily treated using an local anesthetic.

The dermatomes of the thoracic area are marked with letters-numbers that illustrate the connection between the area along with the sensor nerve that serves that area. For instance C1’s spinal nerve doesn’t possess a dermatome, however the other spinal nerves are identified as C1-C8 T9, which corresponds to belly button. Dermatomes are layered in horizontally on the trunk, while dermatomes that are located on the extremities are generally in a longitudinal.

Dermatome Map

The dermatome map is the most common element in textbooks that cover anatomy. The dermatome map is not uniform both inside and inter-textbook. The names are inconsistent, and some textbooks feature different maps on various pages. This can be particularly challenging when the authors of different chapters are not unified in their choice of dermatome map. Many textbooks use the diagrams drawn by Foerster, Keegan, and Garrett however they don’t provide the proper references. Moreover, four textbooks use maps without citations, including one that cites only secondary sources.

Dermatomes are the areas of the skin that receives sensory information from the dorsal root of a spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip lower than horizontally. This is an inherent variation and some tissues may be covered by multiple dermatomes. Additionally, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons from the dorsal limbs.
