Morphologic Studies on Human and Rodent Facial Muscles
Denervation of skeletal muscle fibers results in their atrophy. Early morphologic consequences of acutely denervated human muscle fibers are largely unknown. Conversely, morphologic features of human denervated and neurogenically atrophic muscle fibers have been amply established in chronic disorders such as spinal muscular atrophies and neuropathies. The dynamics of these denervating disorders, which include precise onset, velocity of evolution, and completion of denervation and thereby the nerve-supplied metabolic and electrophysiological inputs from the nerve to the corresponding muscle fibre, are morphologically unexplored.
