Food consistence as factor of the postnatal morphogenesis of mentohyoid muscle of white rats

The aim of the study was to establish the features of postnatal morphogenesis mentohyoid muscles of white rats based morphometry of its structural elements during prolonged power dispersed food. The paper shows that the change in the functional load on the muscles jaw apparatus caused by consumption of finely powdered food, causes a mixed reaction of different types of muscle fibers in the animals of the experimental group. Translation of animals on natural forage for rodents after long dispersed food supply does not restore muscle histology, indicating sustained irreversible changes myosymplasts mentohyoid muscle.
