Schematic representation of muscle multiscale hierarchical structure. Most of the physiological muscle functions are related to its hierarchical organization and components. Physical inactivity causes a decrease in muscle mass and an increase in fat mass, but a chronic high fat diet also increases muscle fat, limiting full muscle function. Muscles quality is often related to skeletal tissue quality. Parameters that quantify the craniofacial muscles quality of an orthodontic patient should constitute the data set to be collected for planning treatment. Adapted from references ⁴⁰ , ⁴¹
