A
This is the portion of the endometrium that lies between the embryo and the stratum basalis. A. decidua basalis B. decidua capsularis C. decidua parietalis D. lamina propria
A
This will become the primary structure for exchange of material between the mother and the fetus. A. chorionic villi of the placenta B. amnion C. amnionic fluid D. embryonic disc

What are the functions of Sertoli cells and Leydig cells? Sertoli cells nourish sperm and Leydig cells produce testosterone. Leydig cells create the blood-testes barrier and Sertoli cells produce androgens. Sertoli cells make up the epididymis and Leydig cells are sperm cells. Leydig cells join seminiferous tubules and Sertoli cells secrete lubrication.
A
All of the following locations for the epididymis, ductus deferens, and ejaculatory duct are correct except: the epididymis is the site of sperm maturation the ejaculatory duct is in the penis the ductus deferens is in the spermatic cord the ductus deferens is the same as the vas deferens
B
All of the following must occur for a sperm cell to fertilize the ovum, except: A. stimulation of uterine motility by sperm progesterone B. acrosomal release of enzymes must be suppressed C. sperm must undergo capacitation D. zona pellucida must be penetrated
B
During which phase of the female reproductive cycle does the endometrial thickness double? A. menstrual phase B. preovulatory phase C. ovulation D. postovulatory phase
B
Uterine contractions during labor are stimulated by a positive feedback loop involving a pituitary hormone called A. vasopressin. B. oxytocin. C. prolactin. D. relaxin
B
What causes follicles to start growing again in a new ovarian cycle? A. decrease in GnRH B. elevation of LH and FSH C. progesterone release D. development of the corpus hemorrhagicum
B
What is "reduced" during meiosis I? the size of the daughter cells the number of chromosomes the growth of nuclei the length of sperm
B
All of the following features are located in the endometrium except: A. stratum functionalis B. stratum basale C. stratum spinosum D. endometrial glands
C
How many days AFTER the first day of a woman's menstrual cycle (her "period") does she ovulate? 0 = It occurs on the same day 7 days 14 days 21 days 28 days
C
This is the connection between the placenta and the embryo. A. amnion B. chorion C. umbilical cord D. placenta
C
What is a function of relaxin? causes sloughing of the endometrium stimulates myometrial contraction inhibits myometrial contraction causes dilation of the cervix
C
Which of the following would indicate false labor? painful contractions contractions increasing in intensity no dilation of the cervix blood-containing mucus in the cervical canal
C
___ hormone, secreted by the ___, controls the ovarian and uterine cycles. A. FSH, anterior pituitary B. LH, anterior pituitary C. GnRH, hypothalamus D. HGH, hypothalamus
C
This is a series of functional changes that sperm go through when they are in the female reproductive tract. acrosomal reaction maturation fertilization capacitation
Capacitation
This develops from the epiblast and carries a protective fluid. A. cytotrophoblast B. yolk sac C. exocoelomic membrane D. amnion
D
What is the source of progesterone and estrogens during early pregnancy? What is the source of progesterone and estrogens during late pregnancy? A. zona pellucida early; corpus luteum late B. corpus luteum early; zona pellucida late C. zona pellucida early; placenta late D. corpus luteum early; placenta late
D
Which of the following does not cover and protect the testes? dartos muscle hypodermis tunica vaginalis tunica cremasteria
D
Which of the following is NOT part of the external genitalia? Vulva Mons pubis Labia majora Labia minora Endometrium
D
Which of the following is released during ovulation? A. primary oocyte B. primary follicle C. secondary follicle D. secondary oocyte
D
what stage is 6 days after fertilization?

This hormone stimulates Leydig cells to secrete testosterone. GnRH LH FSH DHT
LH
What stage is 3-4 days after fertilization

Which of the following is a skeletal muscle component of the scrotum? dartos muscle cremaster muscle internal oblique detrusor muscle
cremaster muscle
Spermatids are the result of two mitotic divisions. mature sperm cells. haploid cells. added to the semen by the prostate gland
haploid
This hormone peaks only after ovulation estrogen. LH. FSH. progesterone.
