Abstract

For some time the anterior lobe of the pituitary gland has been known to occupy a commanding position in the hierarchy of the endocrine system, and consequently has been the focus of intensive investigation. Subsequent to progress in the cytological identification of cell types in the anterior lobe, and with the knowledge that various hormones are released by the anterior lobe, it became the ambition of investigators to determine the cellular site of each hormone. The concensus was that the physiology of the gland could not be fully understood unless a relation was established between its cellular morphology and the distribution of its hormonal functions. In 1938, Severinghaus (40) stated that "to assign a specific cell the actual production of a certain hormone is the ultimate goal of the endocrine cytologist." Studies on the cellular level, though indicative, were undecisive.
