Oviduct- passageway from the ovaries to the outside of the body Labia majora-The outer lips that protect the vagina Uterus- the cavity which holds the baby during pregnancy 3) What are the complementary male sex organs that correspond to the following female organs: oviduct, vagina, labia majora, ovary, clitoris Oviduct- epididymis Vagina- passageway from the ovaries to the outside of the body Labia majora- scrotum Ovary-Teste Clitoris-Penis 4) How are ova and sperm similar? How are they different? They both have the same number of chromosomes, but they are produced in different numbers throughout the month. ) Identify the phases of the menstrual cycle, and what events occur in each stage. Menstrual- the lining of the uterus sheds Follicular-the ovary prepares to release the egg Luteal- the ovary releases the egg 6) What are gonadotropins? What gland secretes them? Provide examples. Hormones secreted by the anterior pituitary. LH and FSH 7) After fertilization, where does an embryo i mplant? In to the uterine wall. 8) How is the sex of a child determined? By the DNA pairs. It’s XX for female and XY for male. 9) What can happen to maternal and paternal genes during crossover of meiosis? They can either be handed down or lost. 0) Identify the role that each of these hormones plays in reproduction: LH, FSH, estrogen, progesterone, testosterone LH-triggers ovulation FSH- regulates the development and growth Estrogen-the primary female sex hormones Progesterone-supports gestation Testosterone-the primary male sex hormone 11) What is required for sperm activity? Seminal Fluid 12) What prevents polyspermy? The cortical reaction 13) What does amniotic fluid contain? What are the important functions that it performs? Made of electrolytes and water that protects the fetus in the womb. 14) What are the events of organogenesis, in order? ctoderm, endoderm, and mesoderm 15) What hormonal changes occur in the mother and fetus at the onset of labor? The baby uses estrogen, oxycotin, and other hormones to determine when and how fast the baby is born. 16) What are the male accessory sex structures? Semin al Vesicles 17) What is the biggest cause of cervical cancer? HPV’s 18) When does the first mitotic division of the zygote occur? Morula 19) Name 3 roles of the uterus. Protects the developing baby, gives it nutrients, and is the site for implantation 20) Identify the characteristics and location of the uterine cervix. assage between the vaginal cavity and the uterine cavity and 4 centimeters long 21) What is the pathway of spermatozoa? Gamete 22) What is the role of seminiferous tubules? Creates spermatoza 23) What organ produces mature sperm? Epidymis 24) What percent of sperm comes from accessory glands? 60 percent 25) How many sperm are in one ejaculate? 300 million 26) What are the 4 main organs of the female? Uterus, Fallopian tube, ovaries, and vagina. 27) What is oogenesis? Creation of the ovum 28-30)Complete the Venn Diagram Chart below. How do the male and female reproductive systems compare?
