FIGURE 1 Mid—polar section through an oocyte in a primordial follicle. Closely applied to the spherical vesicular nucleus is the crescent—shaped Balbiani’s vitelline body (between asterisks at lower right against nucleus) formed by peripheral dense granules (mitochondria) and a central paler area (cytoeentrum) surrounding a dense body. H 48, H —l— 14}. X 560.


FIGURE 2 Note that the cytoplasm of these three oocytes in primordial follicles is strongly reactive for glucose—6—phosphate dehydrogenase. II 54; paraformaldehyde fixative. x 350.


FIGURE 3 The cortical cells and the periphery of the cells in the Wall of the primitive follicles at right are reactive for adenosine~Inonophosphatase. The pronounced activity at the oocyte—follicle cell junction apparently is located in the numerous projections of the follicle cells present in this intereellula.r space. The activity of the enzyme is not maintained at the periphery of differentiating follicular cells of the multilaminous primary follicle at left. H 53; paraformaldehyde fixative. X 350.


FIGURE 4 A low—power survey micrograph through the mid-polar axis of an oocyte in a primordial follicle. Note that most of the organelles are concentrated in one pole of the oocyte; compare with Fig. 9.5. II 44-1; Karnovsky fixative; uranyl and lead stain. X 2700.
