This magnified image of type 2 muscle fibers shows denervation atrophy occurring at the white spaces at the top left and bottom center of the image. The white space represents a disruption of the nerve fibers, resulting in a loss of nerve supply to the muscle fibers.
Denervation is any loss of nerve supply regardless of the cause. If the nerves lost to denervation are part of the neuronal communication to a specific function in the body then altered or a loss of physiological functioning can occur.[1] Denervation can be caused by injury or be a symptom of a disorder like ALS,[2] post-polio syndrome,[3] or POTS.[4][5] Additionally, it can be a useful surgical technique to alleviate major negative symptoms, such as in renal denervation. Denervation can have many harmful side effects such as increased risk of infection and tissue dysfunction.[6]
