![M ^ ' / muscular fibres. According to Rouget^ and His,^ the muscular structure forms the greater part of the ovarian stroma. The latter describes it as consisting essentially of interwoven muscular fibres, which he terms the fusiform tissue, and which he believes to be continuous with the muscular layers of the ovarian vessels. The former believes that the muscular fasciculi accompany the vessels in the form of sheaths, as in erectile tissues. Both attribute to the muscular tissues an important influence in the expulsion of the ovules and in the rupture of the Graafian fol- FiG. 36.

Waldeyer and other writers, however, do not consider it to be so extensively developed as Rouget and His believe. The cortical sub-1 stance is the more important, as that in which the Graafian follicles and I ovules are formed. It consists of interlaced fibres of connective tissue, containing a large number of nuclei. The muscular fibres of the medul- lary substance do not seem to penetrate into it in the human female. In it are fi)und the Graafian follicles, Avhich exist in enormous numbers from the earliest periods of life, and in all stages of development (Fig. 36.) TIie^m(if/m -Fo/^'c/eg.^r-According to the researches of Pfliiger, Waldeyer, and other German writers, the Graafian follicles are formed in early foetal life by (cylindrical inflections of the epithelial, covering of the ovary, which di]) into the substance of the gland.
