Dermatome Map Of The Body – If you’ve ever thought about how the human dermatome chart will look, you’re in the right place. Before we look at the map, let’s discuss what a dermatome actually is. What are the various kinds? Most importantly, what is the reason to understand dermatomes in order to better understand our body. Read on to find out more. You might be amazed! Here are some examples of dermatomes.

What is a Dermatome?

“dermatome” or “dermatome” refers to a tissue that is a part of the cord of the spinal. Dermatomes help doctors to construct maps of the spinal cord that help in diagnosing. Two major maps are accepted by medical specialists. They are the Keegan and Garret map and the Foerster map. These maps were created in the 1930s and remain widely employed. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.

Dermatomes are skin regions which are connected to a particular nerve. In the case of spinal cord injury, the pain could be experienced in a dermatome that is surrounded by the nerve. The same is true for the pain caused by shingles outbreaks can be felt in particular spinal nerves. If you feel discomfort or neurological issue involving the dermatome, you should visit a doctor.

What are Some Examples of Dermatomes?

Dermatomes are a part of skin that is supplied by the spinal nerve. These nerves relay motor, sensory as well as autonomic information. They form part of the peripheral nervous system, that connects the brain to the rest of the body. A dermatome may get affected because of a spinal cord lesion. When one of these dermatomes is injured, it can be easily treated using local anesthetic.

Dermatomes in the thoracic region are labeled with letters-numbers that illustrate the connection between the region and the sensory nerve that is responsible for that area. For example C1 spinal nerve doesn’t have a dermatome, but all spinal nerves in the region are labeled C1 – C8 and T9 is a reference to belly button. Dermatomes are layered in vertically on the trunk those on the extremities tend to be longitudinal.

Dermatome Map

The dermatome map is an integral part of textbooks teaching anatomy. However, the dermatome map is not consistent both within and inter-textbook. The names are inconsistent and some textbooks include different maps on various pages. This is especially problematic when the authors of multiple chapters do not agree on the selection of dermatome map. The majority of textbooks utilize the maps of Foerster, Keegan, and Garrett but don’t include adequate references. Moreover, four textbooks use maps without citations, including one that cites only secondary sources.

The dermatome is the area of skin that receives sensory innervation from the dorsal branch of one spinal nerve. Dermatomes aren’t uniformly located, but they tend to dip more inferiorly than horizontally. This is a normal variation and some tissues may be covered by multiple dermatomes. In addition to this dorsal spinal roots could contain intrathecal intersegmental connections with sensory neurons in the dorsal limbs.
