Chapter 27: Self-Quiz All of the following are barrier contraceptive devices except: IUD contraceptive sponge caps that fit over the cervix diaphragm male condom In humans, spermatogenesis yields ______ sperm for each diploid germ cell, and oogenesis yields ______ secondary oocyte(s) for each germ cell. one, four two, one one, two four, one four, two Which structure adds the final secretions to semen as it moves out of the human reproductive tract? epididymis bulbourethral gland seminal vesicle prostate gland interstitial cells During fetal development, oogonia in human females halt meiosis at the secondary oocyte stage the polar body stage metaphase of meiosis II telophase of meiosis II prophase of meiosis I The primary hormone that inhibits GnRH is FSH LH progesterone acetylcholine a hypothalamic releasing factor The human male gonad is the _________ and the female is the ________. penis ... vagina penis ... uterus scrotum ... ovary testis ... ovary testis ... uterus The function of Sertoli cells is to secrete sex hormones regulate the menstrual cycle regulate spermatogenesis stimulate formation of the corpus luteum change into sperm Which of the following represents the correct path traveled by sperm on their way out of the male? epididymis -> urethra -> vas deferens -> seminiferous tubules seminiferous tubules -> vas deferens -> urethra -> epididymis epididymis -> seminiferous tubules -> vas deferens -> urethra urethra -> vas deferens -> seminiferous tubules -> epididymis seminiferous tubules -> epididymis -> vas deferens -> urethr Menstruation is triggered most directly by a decrease in endometrial thickness estrogen and progesterone the number of follicles FSH and LH FSH and estrogen Colostrum is secreted by the ovary endometrium placenta mammary glands umbilical cord The hormone most directly responsible for ovulation is LH FSH GnRH progesterone chorionic gonadotropin The endoderm gives rise to the lining of the digestive tract epidermis of skin skeletal system muscles nervous system In human development, ectoderm cells migrate through the primitive streak to form endoderm mesoderm the chorion the yolk sac the amnion At the blastula stage, the embryo consists of a mass of cells, each the size of the zygote three differentiated layers of cells a hollow ball of cells cells that have different DNA content a cluster of cells that are much larger than normal cells The brain is derived from mesoderm endoderm ectoderm partly from mesoderm and partly from endoderm partly from endoderm and partly from ectoderm Designed in cooperation with Andrew Stull and Steven Brunasso.
