title: [Ultrastructure of the normal human adrenal cortex].
abstract: Electron-microscopic investigations on the human adrenal cortex have been carried out in order to elucidate ultrastructural differences in the various zones. These studies indicate that certain differences in the ultrastructure of the mitochondria may be particularly useful as criteria to differentiate the three cortical zones. In this regard, the appearance of two types of mitochondria in the zona glomerulosa as well as in the zona fasciculata is of obvious interest. The probability of a relationship between the activity of the different cortical zones and the predominant presence of one form of mitochondria has been suggested. In addition, ultrastructural transformations following stress situations as well as problems dealing with the so-called 'dark and light cells' and the basal membrane are discussed.
