Chronology of Different Systems

The study of cellular communication within the framework of biodynamic osteopathy reveals a chronology essential for understanding embryological development. The first form of communication, autocrine communication, allows a cell to self-inform by ejecting a fluid and reabsorbing it via specific receptors, the glycocalyx. This process highlights the importance of self-knowledge before any interaction with the external environment. Subsequently, paracrine communication emerges, facilitating rapid exchanges between neighboring cells, a crucial mechanism for maintaining homeostasis.

The evolution of cellular communication systems is intrinsically linked to the search for nourishment and the organization of cells into groups. This leads to the formation of structures such as the primitive digestive tube, the connective system, and, later, the circulatory system and the endocrine system. These developments allow for efficient distribution of information and nutrients. The emergence of more complex systems, such as the neuro-enteric system and the first organs, like the primitive heart, illustrates the progression towards sophisticated biological organization. This chronology, which echoes phylogenesis and ontogenesis, is crucial for practitioners, particularly in the evaluation of motor development disorders, where it is often necessary to go back to fundamental systems to understand dysfunctions.
