Fig. 1. Two stages illustrating the development of the ovarian ovum and Graafian follicle in the cat

A shows an early stage, before the complete development of the zona pellucida. It will be observed that the cytoplasm of the follicle cells is. continuous, not only with that of the ovum, but a so with that of the adjacent cells of the same layer, and of the ovarian stroma.

B, later stage, in which it will be noted that the zona pellucida now forms a distinct boundary zone, but does not completely separate the ovum from the cells of the corona radiate. Processes from those cells pass through the zona pellucida, and are continuous with the cyto-reticulum of the ooplasm.
