[The problem of structural modules of the anterior part of the adenohypophysis]

Insufficiency of analytic approach in examination of the structure of adenohypophysis distal part caused the necessity to consider its construction in the aspect of living systems. Compartmentalization, polymeria and multilevelness as fundamental signs of organ level of the gland organization were demonstrated. Markers of different levels compartments and criteria of structural and functional units identification were described. Perspectives of the conception of the gland module organization are connected with consideration mechanisms of hormone production and excretion as well as those of intraorgan structural homeostasis:maintenance of integrity, immune surveillance and autoregulation.
