S2 Dermatome Map – If you’ve ever wanted to know how the human dermatome map is, you’ve come to the right place. Before we look at an image, it’s important to talk about what a dermatome actually is. What are the various types? And, most importantly, why is it important to know about dermatomes in order to comprehend the human body. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes are important in allowing doctors to develop diagrams of the spine that are useful for diagnosis. Two major maps are recognized by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s and are frequently used. The trigeminal and maxillary nerve are among the most extensive dermatomes.

Dermatomes are skin regions that are attached to a particular nerve. In cases of spinal cord injuries, pain may be felt in a dermatome which is controlled by the nerve. Similar to the pain that is caused by an outbreak of shingles is felt by specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome, you should consult with a physician.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin supplied by the spinal nerve. These nerves relay sensory, motor, and autonomic signals. They form a part of the peripheral nerve system which connects brain and all the body. Dermatomes can get affected because of a spinal lesion. When one of these dermatomes becomes injured, it could be treated easily with local anesthetic.

The dermatomes of the thoracic region are labeled with letter-number combinations that show how the region is connected and the sensory nerve that serves that region. For example, the C1 spinal nerve doesn’t have a dematome, however those spinal nerves that are labeled C1 – C8 and T9 refers to belly button. Dermatomes are layered in horizontally on the trunk, however, dermatomes in the extremities are usually linear.

Dermatome Map

The dermatome map is an integral part of textbooks teaching anatomy. But, the map is inconsistent both intra and inter-textbook. The name is not consistent and some textbooks include distinct maps on different pages. This can be particularly challenging when the authors of multiple chapters do not agree on the selection of dermatome map. Most textbooks use Maps of Foerster, Keegan, and Garrett but do not include adequate references. Additionally, four textbooks employ maps with no citations, and one of them is one that cites only secondary sources.

Dermatomes are the regions of the skin that receives sensory information from the dorsal roots of one spinal nerve. Dermatomes aren’t uniformly situated, but they tend to dip less inferiorly than horizontally. This is a normal variation and some tissue types are covered with more than one. Additionally, dorsal spinal rootlets may have intrathecal intersegmental anastomoses with sensory neurons from the dorsal parts of the limbs.
