Figure 3–1b Each spermatogonium produces four haploid spermatozoa. Figure 3–5 Formation of primary germ layers. A, Implantation of a 71⁄2-day blastocyst in which the cells of the embryonic disc are separated from the amnion by a fluid-filled space. The erosion of the endometrium by the syncytiotrophoblast is ongoing. B, Implantation is completed by day 9, and extraembryonic mesoderm is beginning to form a discrete layer beneath the cytotrophoblast. C, By day 16 the embryo shows all three germ layers, a yolk sac, and an allantois (an outpouching of the yolk sac that forms the structural basis of the body stalk, or umbilical cord). The cytotrophoblast and associated mesoderm have become the chorion, and chorionic villi are developing. Source: Adapted from Marieb, E. N. (1998). Figure 3–4 During ovulation, the ovum leaves the ovary and enters the fallopian tube. Fertilization generally occurs in the outer third of the fallopian tube. Subsequent changes in the fertilized ovum from conception to implantation are depicted.

Arrows indicate the direction of blood flow. Maternal blood flows through the uterine arteries to the intervillous spaces of the placenta and returns through the uterine veins to maternal circulation. Fetal blood flows through the umbilical arteries into the villous capillaries of the placenta and returns through the umbilical vein to the fetal circulation. Figure 3–7 Early development of primary embryonic membranes. At 41⁄2 weeks, the decidua capsularis (placental portion enclosing the embryo on the uterine surface) and decidua basalis (placental portion encompassing the elaborate chorionic villi and maternal endometrium) are well formed. The chorionic villi lie in blood-filled intervillous spaces within the endometrium. The amnion and yolk sac are well developed. Source: Adapted from Marieb, E. N. (1998).
