Advances in the pathophysiology of muscular atrophy (literature review)

Abstract

Muscle atrophy is a common clinical sign. In recent years, a great deal of research has been done on the morphology, biochemistry, functional changes and etiology of muscular atrophy, and great progress has been made. These achievements have certain guiding significance for clinical work. 1. Ultrastructure and biochemistry of skeletal muscle fibers Striated muscle cells (muscle fibers) are mainly composed of sarcolemma, sarcoplasm, myofibrils and nuclei (see Table 1)
