Uterus Septus Bilocularis.—Complete union of the two filamentsof Muller has taken place, but the common wall, formed by their coa-lescence, persists. We have thus two distinct uterine cavities. Theseptum may extend the whole length of the vagina, and give rise to adouble vagina; or absorption of the vaginal septum and a portionof the uterine septum may have taken place, so that we may have adouble uterine cavity with a single cervix, uterus semi-par Fig. 28.—Uterus semi-partitus. (Gravel.) DEVELOPMENT OF THE OVUM. 35 PHYSIOLOGY OF THE OVUM, CHAPTER II. DEVELOPMENT OF THE OVUM. The Graafian follicles and the ovum.—Discharge of the ova from the ovary, and theformation of the corpus luteum.—The migration of the ovum.—Fecundation.—Changes taking place in the ovum subsequent to fecundation.—Nourishment of theembryo.—The allantois and chorion.—The deciduae.—The placenta; its developmentand structure.—Formation of the umbilical cord.—The amniotic fluid. The physiology of the ovum comprises its genesis, development,and discharge from the ovary, its fecundation, and the entire seriesof subsequent changes by which the simple structure of the germbecomes converted into a complex organism presenting the specificcharacteristics of the parent. • -WMlhi WK Wi^lMM CM \
