Dermatome Map Shingles Leg – If you have ever wondered what the human dermatome’s map is, you’ve come to the right place. Before we go to this map, lets look at what a dermatome is. What are the various types? And, most importantly, why is it important to know about dermatomes in order to better understand our body. Read on to find out more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes help doctors to develop diagrams of the spine, which aid in the diagnosis. Two major maps are recognized by medical experts. They are the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and are often utilized. The trigeminal nerve , as well as the maxillary nerve are the biggest dermatomes.
Dermatomes are skin areas that are linked to a specific nerve. In cases of spinal cord injury, pain can be experienced in a dermatome that is innervated by that nerve. Similar to the pain that is caused by an outbreak of shingles can be felt in specific spinal nerves. If you suffer from neurologic condition or pain that involves the dermatome area, you must visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin that is provided by a single spinal nerve. The nerves transmit motor, sensory, and autonomic information. They form an element of the peripheral nervous system that connects the brain to the all the body. Dermatomes can get affected because of a spinal injury. If one of these is injured, it can be treated easily with an local anesthetic.
The dermatomes of the thoracic area are marked with letter-number combinations that show how the region is connected as well as the nerve which supplies that area. For instance C1’s spinal nerve does not possess a dermatome, however those spinal nerves that are labeled C1 – C8 and T9 is a reference to the belly button. Dermatomes are layered vertically on the trunk while dermatomes on the extremities tend to be in a longitudinal.
Dermatome Map
The dermatome map is a common feature of textbooks that cover anatomy. However, the dermatome map is inconsistent both intra and inter-textbook. Its name isn’t consistent and certain textbooks have different maps on various pages. This is particularly problematic when the authors of multiple chapters differ in their choice of dermatome map. A majority of textbooks employ the Maps of Foerster, Keegan, and Garrett however they don’t provide the proper references. Additionally, four textbooks employ maps that do not have citations, such as one that only cites secondary sources.
Dermatomes are the parts of skin that receives sensory stimulation from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly placed, however they tend to dip lower than horizontally. This is a normal variation and certain tissue types are covered with more than one. Additionally dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons that originate from those limbs that are dorsal.
