front 1 The primary function of the uterus is to: | back 1 receive, retain, and nourish a fertilized ovum. |
front 2 Human egg and sperm are similar in that | back 2 they have the same number of chromosomes |
front 3 All of the following can be considered male secondary sex characteristics except the | back 3 development of testes as opposed to ovaries. |
front 4 Effects of estrogen include: | back 4 growth of the breasts at puberty. |
front 5 Which of the following occurs as a result of undescended testes? | back 5 Inadequate or nonviable sperm will be produced |
front 6 Normally menstruation occurs when: | back 6 blood levels of estrogen and progesterone decrease. |
front 7 Which of the following will occur after ovulation? | back 7 The endometrium enters its secretory phase |
front 8 Which of the following is a correct statement about uterine tubes | back 8 The infundibulum is the funnel-shaped region near the ovary |
front 9 All of the following statements referring to the uterine cycle are true except: | back 9 FSH and LH directly promote development of the uterine endometrium. |
front 10 The sperm's acrosome ____________________. | back 10 contains enzymes .The enzymes allow the sperm to penetrate the egg. |
front 11 Which cell type is actually ovulated from the ovary | back 11 Secondary oocyte |
front 12 Ovulation in a typical or "average" cycle usually occurs on day ____________________. | back 12 14 |
front 13 Milk ejection or let-down reflex is stimulated by which of the following hormones associated with pregnancy? | back 13 oxytocin |
front 14 Which of the following is a highly unlikely method of producing a child? | back 14 ectopic implantation |
front 15 The umbilical arteries carry: | back 15 waste products to the placenta. |
front 16 Select the correct statement about fertilization | back 16 millions of sperm cells are destroyed by the vagina's acidic environment. |
front 17 Following fertilization the zygote goes through a rapid period of cell divisions called ____________________. | back 17 cleavage/This results in the blastocyst, which has many smaller cells. |
front 18 The hormone that induces labor and controls labor via a positive feedback mechanism is ____________________. | back 18 oxytocin/This hormone is produced in the mother's hypothalamus |
front 19 Implantation of the blastocyst begins ____________________. | back 19 6-7 days after ovulation. |
front 20 Match the reproductive hormone with the correct characteristic. | back 20 Testosterone – Produced by interstitial cells GnRH – Produced in the hypothalamus FSH – Stimulates oogenesis directly on follicle cells Progesterone – Produced during the second half of ovarian cycle LH – Directly stimulates interstitial cells in males, |
front 21 Correctly match the following. | back 21 LH surge – Causes ovulation Estrogen – Causes growth spurt at puberty Testosterone – Responsible for sex drive in females Progesterone – Promotes secretory phase of uterine cycle |
front 22 Match the structures with their functions | back 22 Oxytocin – Causes contraction of uterus near the end of pregnancy Estrogen – Rises throughout pregnancy Relaxin – Causes pelvic ligaments and pubic symphysis to become more flexible hCG (human chorionic gonadotropin) – Lets the corpus luteum know you are pregnant Progesterone – Quiets the uterus during pregnancy |
front 23 Explain the function of the myometrium and endometrium. | back 23 The myometrium plays an active role during childbirth when it contracts rhythmically to force the baby out of the mother's body. The endometrium is the innermost lining of the uterus where the embryo implants and stays for the rest of its development. |
front 24 What signals the corpus luteum to continue producing hormones if the oocyte is fertilized | back 24 Once the embryo has implanted, it sends out its own hormone, human chorionic gonadotropin, which stimulates the corpus luteum to maintain and even increase its hormone production. |
front 25 What is the physiological importance of the fact that the male testes descend to reside in the scrotal sac? | back 25 The male testes descend into the scrotal sac so that a fairly constant intrascrotal temperature is maintained. Failure of the testes to descend results in sterility, because production of viable spermatozoa requires a temperature several degrees lower than normal body temperature. |
