Abstract
Changes in the mitochondrial compartment are the central element in the morphogenesis of musculoskeletal abnormalities in early aging OXYS rats. Compensatory hyperplasia and hypertrophy with enlargement of the working surface area are seen in these organelles at the age of 2 months. The mitochondria are characterized by polymorphism, compact packing of cristae. By the age of 9 months destructive changes and sharp reduction of the mitochondrial compartment are observed is many myocytes. Disorders in the mitochondrial structure and function and oxidative stress can be among the causes of degenerative changes in the myofibrillar system and other structures of muscle fibers, including those resultant from activation of apoptosis.
