Dermatome Map Of Foot – If you’ve ever wanted to know what the human dermatome’s map looks, you’ve come to the right place. Before we get to our map, we’ll discuss the definition of a dermatome. What are the different kinds? And most importantly, what is the reason to understand dermatomes in order to comprehend our body. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that covers the spine. Dermatomes help physicians to build maps of the spinal cord that are useful for diagnosis. Two major maps are recognized by medical experts. They are the Keegan and Garret map and the Foerster map. The maps were designed in the 1930s and remain often employed. The trigeminal nerve and the maxillary nerve are the largest dermatomes.

Dermatomes are skin areas that are linked to a specific nerve. In the case of spinal cord injury, pain can be felt in a dermatome that is connected to that nerve. Similarly, the pain caused by an outbreak of shingles is felt by specific spinal nerves. If you feel pain or neurological condition involving the dermatome area, you must consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin that is provided by only one spinal nerve. These nerves provide motor, sensory, and autonomic information. They form part of the peripheral nerve system, that connects the brain to the other parts of the body. A dermatome may get affected because of a spinal cord lesion. When one of these dermatomes gets injured, it is able to be easily treated using an local anesthetic.

The dermatomes of the thoracic region have been labeled with letters-numbers that illustrate the relationship between the area in question and the sensory nerve that serves that region. For example the C1 spinal nerve doesn’t have a dermatome, but others spinal nerves have been identified as C1-C8 T9, which corresponds to belly button. Dermatomes are layered horizontally along the trunk, those that are located on the extremities are generally in a longitudinal.

Dermatome Map

The dermatome map is one of the common features of textbooks that teach anatomy. But, the map is inconsistent both intra and inter-textbook. Its name isn’t consistent as are some textbooks that have distinct maps on different pages. This can be particularly challenging in the event that the authors of various chapters differ in their choice of dermatome maps. Many textbooks use the Maps of Foerster, Keegan, and Garrett but do not include proper references. Moreover, four textbooks use maps that do not have citations, such as one that refers to only secondary sources.

Dermatomes are the areas of skin that receives sensory input from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly located, but they tend to dip less inferiorly than horizontally. This is an inherent variation and some tissue types are covered with more than one. Additionally dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons of Dorsal limbs.
