Abstract
The microstructure and ultrastructure of the adrenal cortex of the rhesus monkey(Macaca mulatta) were studied by means of light and electron microscopy.The adrenal cortex was divided into the zona glomerulosa,the zona fasciculata and the zona reticularis.It had following characteristics:(1)The capsula was thicker,occasionally entered the zona glomerulosa and divided its cells into globoids.(2)Occasionally the finger-shaped structure of the zona glomerulosa entered the zona fasciculata and the zona reticularis,and had chromaffin cells in it;the zona glomerulosa cells could be classified into 2 types,i.e.light cells and dark cells,and they formed globoids,follicles,cords and irregular shapes.(3)The zona reticularis was thicker,some of them could be divided into outer zone and inner zone;occasionally the thorn-like structure of the zona reticularis entered the zona fasciculata;and the zona reticularis cells occurred in the subcapsula or in the medulla.(4)Occasionally the finger-shaped structure of the capsula with the cortex entered the medulla.(5)All the cortex cells contained abundant lysosomes,mitochondria and endoplasmic reticula,but the lipid droplets in different zone cells varied in number,size,shape and electron density.
