Dermatome Leg Map – If you’ve ever wondered how the human dermatome chart is, you’ve come to the right spot. Before we get to our map, we’ll discuss what a dermatome actually is. What are the different types? Most importantly, why is it essential to be aware of dermatomes order to know more about the human body. Continue reading to learn more. You may be surprised! Here are some examples of dermatomes.

What is a Dermatome?

“dermatome,” or “dermatome” refers to a tissue that covers the spine. Dermatomes are important in allowing doctors to construct maps of the spinal cord, which aid in the 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 commonly utilized. The trigeminal nerve as well as the maxillary nerve are the largest dermatomes.

Dermatomes are skin areas that are linked to a particular nerve. In cases of spinal 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 with a physician.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin supplied by one spinal nerve. The nerves transmit motor, sensory, and autonomic messages. They form an element of the peripheral nervous 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 easily treated with local anesthetic.

The dermatomes of the thoracic region have been labeled using letter-number sequences that demonstrate the connection between the area and the sensory nerve that supplies that area. For instance the C1 spinal nerve does not have a dematome, however those spinal nerves that are labeled C1 – C8 T9, which corresponds to belly button. Dermatomes are layered horizontally along the trunk, while dermatomes in the extremities are usually longitudinal.

Dermatome Map

Dermatome maps are a common feature of textbooks teaching anatomy. But, the map is inconsistent both intra and inter-textbook. The name is not consistent and some textbooks include different maps on various pages. This is particularly problematic when the authors of multiple chapters are not unified in their choice of dermatome map. Most textbooks use maps of Foerster, Keegan, and Garrett however, they do not provide proper references. Moreover, four textbooks use maps without citations, including one that only cites secondary sources.

The dermatome is the area of skin that receives sensory innervation from the dorsal branch of one spinal nerve. Dermatomes aren’t always evenly situated, but they tend to dip less inferiorly than horizontally. This is a natural variation and some tissues may be covered by multiple dermatomes. Also dorsal spinal rootlets could have intrathecal intersegmental anastomoses to sensory neurons that originate from those limbs that are dorsal.
