What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that is a part of your spinal cord. Dermatomes play a crucial role in allowing doctors to create models of the cord, which aid in the diagnosis. Two major maps are recognized by medical professionals. The Keegan and Garret map and the Foerster map. These maps were developed in the 1930s and are frequently employed. The trigeminal nerve and the maxillary nerve are the largest dermatomes.

Dermatomes are skin areas that are linked to a particular nerve. In cases of spinal cord injury, pain may be felt in a dermatome which is surrounded by the nerve. The same is true for the pain caused by an outbreak of shingles can be felt in particular spinal nerves. If you feel discomfort or neurological issue involving the dermatome, it is recommended that you visit a doctor.

What are Some Examples of Dermatomes?

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

Dermatomes in the thoracic region are labeled with letter-number combinations that show the relationship between the area as well as the nerve that supplies that area. For instance the C1 spinal nerve doesn’t have a dermatome, but others spinal nerves have been labeled as C1-C8 and T9 is a reference with the belly button. Dermatomes are laid vertically on the trunk while dermatomes in the extremities are usually 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 some textbooks feature different 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 map. Most textbooks use map of Foerster, Keegan, and Garrett however they don’t provide appropriate references. Additionally, four textbooks employ maps with no citations, and one of them is one that refers to only secondary sources.

Dermatomes are the areas of skin that receives sensory innervation from the dorsal root of one spinal nerve. The dermatomes are not uniformly found, but they tend to dip less inferiorly than horizontally. This is a normal variation and certain tissues are covered by more than one dermatome. In addition to this dorsal spinal rootlets could be anastomosed with intrathecal intersegmental sensory neurons in those limbs that are dorsal.
