ovary; luteinizing hormone
Corpus luteum; Progesterone
The development of the corpus luteum occurs during the __________ cycle.
Uterine
Ovarian

Ovarian
When do the oogonia undergo mitosis?
before birth
at puberty
at the beginning of each menstrual cycle
during fertilization
Before Birth
From what structure does the corpus luteum originate?
uterine corpus
dominant follicle
Fallopian tube
corpus albicans
Dominant Follicle
Why do estrogen levels fall after menopause?
The ovaries degrade.
There are no follicles left to produce estrogen.
The pituitary secretes a menopause-specific hormone.
The cells of the endometrium degenerate
There are no follicles left to produce estrogen.
The vulva includes the ________.
lactiferous duct, rugae, and hymen
lactiferous duct, endometrium, and bulbourethral glands
mons pubis, endometrium, and hymen
mons pubis, labia majora, and Bartholin’s glands
mons pubis, labia majora, and Bartholin’s glands
In what part of the ovary contains a large number of primordial follicles?
Cortex
Hilum
Medulla
Cortex
What is the main hormone that helps primordial follicles develop into primary follicles?
Luteinizing hormone
Estrogen
Follicle-stimulating hormone (FSH)
Estriol
FSH
The surge in LH that occurs during the middle of the ovarian cycle triggers ???
Uterine-lining secretion Activation of primordial follicles FSH release Menstruation Ovulation
Ovulation
The basic difference between spermatogenesis and oogenesis is that ?
One mature ovum is produced in oogenesis, and four mature sperm are produced in spermatogenesis.
The organ that makes estrogen and progesterone is the __________.
The ovaries, which make estrogen and progesterone, are the primary sex organs of the female.
The surge in LH that occurs during the middle of the ovarian cycle triggers __________.
The surge in LH that occurs during the middle of the ovarian cycle triggers ovulation, which occurs, on average, at day 14 of the monthly cycle.
Which cell type is actually ovulated from the ovary?
Secondary oocytes are ovulated from the ovary. Females do NOT ovulate true egg cells.
Within the ovary, progesterone is produced by the __________.?
Within the ovary, progesterone is produced by the corpus luteum.
What hormone is responsible for the secondary sex characteristics found in women?
Estrogen is responsible for the secondary sex characteristics in women.
The muscular wall of the uterus is called the __________.
The muscular wall of the uterus is the myometrium
Theca Cells work with Granulosa cells to create what hormone?
They are Estrogen producing cells in a maturing ovarian follicle
After the mature follicle has ovulated the secondary oocyte, the follicle turns into a corpus luteum. The change in structure, alter what hormone the Theca & Granulosa cells produce.
Which is it?
a. Estrogen
b. FSH
c. Progestrone
d. LH
C. Progesterone
Instead of estrogen, granulosa and theca cells produce large amounts of progesterone.
Progesterone triggers negative feedback at the hypothalamus and pituitary, which keeps GnRH, LH, and FSH secretions low, so no new dominant follicles develop at this time.
Post-Ovulation progesterone ‘luteal phase’ maintains a thick stratum functionalis (Endometrial lining Uterus). As long as a functional corpus luteum is present, the endometrial lining is prepared for implantation. If an embryo is not implanted on the wall, what follows next?
If an embryo does not implant = no signal sent to corpus luteum = degrades = ceasing progesterone production = ending luteal phase.
W/O progesterone, the endometrium thins and prostaglandins cause the arteries to constrict and rupture, preventing oxygenated blood from reaching the endometrial tissue = death (menses)
During the days 0 - 3 in the follicular phase of the ovarian cycle. Progesterone, FHS and LH are
High or Low?
Early days of the follicular phase of the ovarian cycle = progesterone, FSH, and LH levels are low.
Recall that progesterone concentrations decline as a result of the degradation of the corpus luteum, marking the end of the luteal phase. This decline in progesterone triggers the shedding of the stratum functionalis of the endometrium
What marks the beginning of the proliferative phase of the menstrual cycle?
a. Granulosa and theca cells increase estrogen serum levels which stimulate the rebuilding of the endometrial lining
b. Granulosa and theca cells increase progesterone serum levels which stimulate the rebuilding of the endometrial lining
a. It occurs when the granulosa and theca cells of the tertiary follicles begin to produce increased amounts of estrogen. These rising estrogen concentrations stimulate the endometrial lining to rebuild.
.
What marks the end of the proliferative cycle?
a. ovulation
b. Menstruation
c. Follicular phase
d. A mature zygote binding to endothelium
In a typical 28-day menstrual cycle, ovulation occurs on day 14. Ovulation marks the end of the proliferative phase as well as the end of the follicular phase
What are the 3 functions of the Vagina?
As found in the required readings for revision
- Penetrative Sex
- A channel for the elimination of vaginal secretions and menstrual flow
- Birth Passage
