All of the following are functions of the ovaries except:
A. Production of eggs
B. Maintaining the development of a fetus
C. Production of estrogen
D. Development of the corpus luteum
Correct answer: B
Rationale: The ovaries produce ova and secrete hormones such as estrogen and
progesterone and are involved in corpus luteum formation. Maintaining fetal development
occurs in the uterus, not the ovaries.
Which of the following statements is true concerning oogenesis?
A. It begins at the time of puberty.
B. The primary oocyte divides to produce a secondary oocyte.
C. Each primary oocyte produces two to three mature ova.
D. The first polar body maintains all the cytoplasm.
E. B and C are true
Correct answer: B
Rationale: During oogenesis, a primary oocyte undergoes meiosis to form a secondary
oocyte and a polar body. Oogenesis begins before birth, produces one mature ovum, and
most cytoplasm is retained in the secondary oocyte.
Ovulation occurs when an egg is released from the:
Correct answer: Ovarian follicle
,Rationale: Ovulation is the release of a mature oocyte from a ruptured ovarian follicle.
Name the specific region of the female reproductive system highlighted in blue and
indicated by the arrow.
Correct answer: Fimbriae (infundibulum)
Rationale: The fimbriae are finger-like projections of the infundibulum that help guide the
ovulated egg into the fallopian tube.
Which layer of the uterus contracts during labor?
A. Endometrium
B. Mucosal coat
C. Perimetrium
D. Myometrium
E. Serous coat
Correct answer: D
Rationale: The myometrium is the thick smooth muscle layer of the uterus responsible for
uterine contractions during labor.
Which of the following statements is false concerning the vagina?
A. The fundus is made of elastic fibers, blood vessels, lymph vessels, and nerves.
B. Vaginal moisture is achieved by mucus from the cervix.
C. Elastic fibers give the vaginal wall elasticity.
D. The mucosal lining can extend.
Correct answer: A
Rationale: The vagina does not have a fundus; the fundus is a part of the uterus. The
remaining statements accurately describe vaginal structure and function.
Describe the purpose of the cervix prior to ovulation.
Correct answer: Just prior to ovulation, the cervix softens, swells, and secretes thin mucus
that facilitates sperm entry into the uterus and improves sperm survival.
Rationale: Hormonal changes around ovulation make cervical mucus more permeable to
sperm.
, Label the regions of the female external reproductive system.
Correct answer:
A: Prepuce
B: Urethral orifice
C: Vestibule
Rationale: These structures are components of the vulva and serve protective and functional
roles in urination and reproduction.
True or False: Each mammary gland contains 12–24 lobules.
Correct answer: True
Rationale: Mammary glands are composed of multiple lobules that contain alveoli
responsible for milk production.
True or False: Milk is not produced during pregnancy because of elevated estrogen and
progesterone levels.
Correct answer: True
Rationale: Estrogen and progesterone inhibit milk secretion during pregnancy despite
mammary gland development. Milk production begins after hormone levels drop
postpartum.
Blood tests indicate that progesterone and estrogen levels are both increased. The patient is
most likely in which phase of the uterine cycle?
A. Menstrual phase
B. Proliferative phase
C. Secretory phase
D. Luteal phase
E. Follicular phase
Correct answer: C
Rationale: The secretory phase is characterized by elevated progesterone and estrogen,
preparing the endometrium for possible implantation.
