Which of the following rows identifies the site of fertilization and the area in which a fertilized egg implants, respectively? Select one: a. Site of Fertilization Site of Implantation Fallopian tube Endometrium b. Site of Fertilization Site of Implantation Uterus Placenta c. Site of Fertilization Site of Implantation Uterus Endometrium d. Site of Fertilization Site of Implantation Fallopian tube Placenta
Which of the following rows correctly identifies the locations of fertilization and the development of the fertilized ovum? Select one: a. Fertilization Development of the fertilized ovum Fallopian tube Uterus b. Fertilization Development of the fertilized ovum Ovary Uterus c. Fertilization Development of the fertilized ovum Fimbriae Endometrium d. Fertilization Development of the fertilized ovum Uterus Endometrium
Which of the following rows identifies structures responsible for maintaining the endometrium before and after implantation? Select one: a. Before Implantation After Implantation Corpus luteum Placenta b. Before Implantation After Implantation Maturing follicle Placenta c. Before Implantation After Implantation Corpus luteum Trophoblast d. Before Implantation After Implantation Maturing follicle Trophoblast
There are 6 major events in fertilization. Discuss the process of fertilization or conception, with emphasis on the sperm-egg interaction. Proteins on the sperm plasma membrane bind to ZP3 molecules within the zona pellucida of the egg. Why is this event important? Zona binding triggers the acrosome reaction, in which the sperm plasma membrane fuses with the outer acrosomal membrane, causing exocytosis of acrosomal contents. What is in the "acrosomal content"? Acrosomal enzymes begin to dissolve a hole in the zona pellucida. This enzymatic degradation, accompanied by rapid sperm tail beating, moves the sperm through the zona. Where does the sperm intend to reach?
Which of the following rows identifies structures responsible for maintaining the endometrium before and immediately after implantation? Select one: A. Before Implantation After Implantation Corpus Luteum Placenta B. Before Implantation After Implantation Maturing Follicle Placenta C. Before Implantation After Implantation Corpus Luteum Trophoblast D. Before Implantation After Implantation Maturing Follicle Trophoblast
ARRANGE THE FOLLOWING EVENTS IN CORRECT SEQUENCE from 1-13: Penetration of the zona pellucida Cortical reaction 1st cleavage Acrosomal membranes rupture, and release their enzyme contents Penetration of the corona radiata Depolarization of egg membranes Migration of cortical cytoplasm to form gray crescent Sperm attach loosely on the zona pellucida Zona reaction Oocyte completes meiotic division ZP3 tenaciously binds acrosome-intact sperm Release of Ca+2 in egg cytoplasm from its bound state Amphimixis
Which row correctly identifies the function and source of hCG, respectively? Select one: a. Function Source Stimulates FSH Anterior pituitary b. Function Source Aids implantation Uterus c. Function Source Maintains corpus luteum Trophoblast and placenta d. Function Source Stimulates estrogen Ovary
Which of the following statements does NOT correctly describe the events following fertilization? Select one: a. Only the inner cell mass cells in a blastocyst are pluripotent. b. The trophoblast has an important role in maintaining the pregnancy, as it prevents the endometrium from shedding. c. As hCG takes over maintaining the endometrium immediately after implantation, the corpus luteum degenerates into the corpus albican. d. All 16 cells in a morula are truly totipotent, meaning that they can become any cells in the human body.
Superovulation is when women take hormones in order to release more eggs for fertilization. Which of the following rows contains hormones that are involved in developing the follicles and releasing them from the ovary, respectively? What could be the unintended consequence of this process? Select one: a. Hormone Unintended Consequence FSH and LH The formation of twins or multiple births b. Hormone Unintended Consequence FSH and LH A tubal ligation c. Hormone Unintended Consequence FSH and LH Scar tissue on the Fallopian tubes d. Hormone Unintended Consequence LH and FSH Ovarian Cancer
Which of the following statement does NOT correctly describe the event of the following fertilization? Select one: A. As hCG takes over maintaining the endometrium immediately after implantation, the corpus luteum degenerates into the corpus albican. B. All 16 cells in a morula are truly totipotent, meaning that they can become any cells in the human body. C. The trophoblast has important in maintaining the pregnancy, as it prevents the endometrium from shedding. D. Only inner cells mass in a blastocyst is pluripotent.
For each hormone, select whether the hormone is increasing or decreasing at the beginning of parturition. In addition, select the correct effect that the change in hormone secretion causes. Hormone Levels Resulting Effect Increasing Decreasing Causes the endometrial layer to break away from the uterus Causes the endometrial layer to be maintained Increases uterine contractions Decreases uterine contractions Increases milk production in the mother's breasts Decrease milk production in the mother's breasts Hormone Hormone Levels Resulting Effect Estrogen Progesterone Oxytocin Prostaglandins Prolactin
