[The contribution of molecular biology to the progress of the physiological sciences]

Life science, physiology have an important improvement on cell sciences, by seeing cell through a complex integrative concept. So, the notion of homeostatic equilibrium for the whole body is applied at the cellular level. Also, molecular biology techniques can facilitate the answer for a lot of the physiological and pathological questions. This paper mention only some of the many examples which justify both the importance of molecular biology for the cognitive progress of physiological and biomedical sciences and the role of physiological notions for the complexity view of molecular sciences.
