Lumbar Disc Herniation – If you’ve ever wondered how the human dermatome map is, you’ve come to the right place. Before we look at this map, lets look at the definition of a dermatome. What are the various kinds? Most importantly, why is it essential to learn about dermatomes in order to know more about your body. Read on to find out more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?
The term “dermatome” refers to a tissue that covers the cord of the spinal. Dermatomes are important in allowing doctors to construct maps of the spinal cord that aid in the diagnosis. Two major maps are accepted by medical professionals. The Keegan and Garret map and the Foerster map. The maps were designed in the 1930s, and are widely employed. The trigeminal and maxillary nerve are the largest dermatomes.
Dermatomes are skin areas that are linked to a particular nerve bundle. When there is a spinal cord injury, pain can be experienced in a dermatome that is controlled by the nerve. In the same way, the pain triggered by shingles outbreaks is felt by specific spinal nerves. If you suffer from pain or neurological condition involving the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?
Dermatomes are segments of skin supplied by only one spinal nerve. These nerves carry sensory, motor, and autonomic signals. They form part of the peripheral nervous system which connects brain and rest of the body. A dermatome may suffer from a spinal cord lesion. When one of these dermatomes becomes injured, it could be treated easily with a local anesthetic.
The dermatomes of the thoracic region are labeled by letter-number combinations, which show the relationship between the area in question and the sensory nerve which supplies that region. For example C1 spinal nerve does not have a dermatome, but the other spinal nerves are labeled C1-C8, while T9 corresponds to the belly button. Dermatomes are layered in horizontally along the trunk, however, dermatomes that are located on the extremities are generally longitudinal.
Dermatome Map
Dermatome maps are one of the common features of textbooks that cover anatomy. However, the dermatome maps is inconsistent both intra and inter-textbook. The names are inconsistent as are some textbooks that have distinct maps on different pages. This is especially problematic in the event that the authors of various chapters are not unified in their choice of dermatome maps. Many textbooks use the map of Foerster, Keegan, and Garrett however, they do not provide the proper references. Additionally, four textbooks employ maps with no citations. This includes one that uses only secondary sources.
Dermatomes are the areas of skin that receives sensory input from the dorsal roots of one spinal nerve. Dermatomes aren’t evenly located, but they tend to dip lower than horizontally. This is a natural variation, and some tissue types are covered with more than one. Also dorsal spinal nerve roots may contain intrathecal intersegmental connections with sensory neurons that originate from the dorsal limbs.
