senile atrophy the natural atrophy of tissues and organs occurring with advancing age.
spinal muscular atrophy progressive degeneration of the motor cells of the spinal cord, beginning usually in the small muscles of the hands, but in some cases (scapulohumeral type) in the upper arm and shoulder muscles, and progressing slowly to the leg muscles. Called also Aran-Duchenne disease, Cruveilhier's disease, and Duchenne's disease.
subacute yellow atrophy submassive necrosis of the liver associated with broad zones of necrosis, due to viral, toxic, or drug-induced hepatitis; it may have an acute course with death from liver failure occurring after several weeks, or clinical recovery may be associated with regeneration of the parenchymal cells.
