In support of this view Honore points out that there are no indications of degeneration or destruction of the follicular epithelial cells of the ripe foUicles during oestrus, and moreover, that these cells are retained in the foUicle at the time of ovula- tion, giving rise subsequently to the luteal cells of the corpus luteum. It would appear possible, however, that the liquor folhcuh is formed partly by the secretory activity, and partly. Fig. 30.—Young human Graafian follicle. The cavity contains the liquor fol

(From Sellheim.) by destruction of the folhcle cells, just as, according to one view, milk is derived from both the secretion and the disintegra- tion of the cells of the mammary gland (see p. 560). Heape ^ states that during the growth of the ovum nour- ishment is supphed to it by the aid of the discus proUgerus, for fine protoplasmic processes may be seen passing from the cells of this layer and projecting into radiating canals in the zona which encloses the ovum, being in contact with the vitelhne membrane.
