Mechanics applied to skeletal ontogeny and phylogeny

摘要: The musculo-skeletal system serves the mechanical function of creating motion and transmitting loads. It is made up mainly four components: bone, cartilage, muscle fibrous connective tissue. These have evolved over millions years into complex diverse shapes animal skeleton. skeleton, however, not built to a static plan: it can adapt forces during growth, remodel if change, regenerate damaged. In this paper, regulation skeletal construction by analyzed from both ontogenetic phylogenetic standpoints. first part, models biomechanical processes that act ontogenesis – tissue differentiation bone remodeling are presented and, in second, evolution middle ear used as an example change phylogenesis. Because constitutive laws for tissues relatively well understood, because skeleton preserved fossil record, application mechanics seems present good opportunity explore relationships governing adaptations change.
