Unit 15
Luteal phase of menstruation
Corpus luteum is formed, secretion of estrogen continues and a large amount of progesterone is secreted
The granulosa cells of developing follicles work with thecal cells to produce
Estrogens
What is not produced by the ovary? estrogen ova progesterone FSH inhibin
FSH
A rise in the blood levels of follicle-stimulating hormone at the beginning of the ovarian cycle is responsible for
Follicle maturation
Rupture of the mature follicle results in
Ovulation
The surge in luteinizing hormone that occurs during the middle of the ovarian cycle triggers
Ovulation
Which ovarian structure remains in a state of suspended development until the individual reaches puberty?
Primary oocyte
Menstruation is triggered by a drop in the levels of
Progesterone
Which is the resulting event if fertilization does not occur?
The corpus albicans is formed.
following ovulation, the remnants of the ovulated follicle enlarge and become a
corpus luteum
secondary oocyte does NOT occur unless
fertilization occurs
Fimbrae
finger-like projections that accept the egg from the ovary to the Fallopian tubes
menses (menstruation)
functional layer of endometrium of uterus is destroyed and expelled
the female reproduction cycle is regulated by
hypothalamus-pituitary-ovarian axis
Secretion of Progesterone
prepares endometrium for possible implantation
mature follicle
primary oocyte matures and develops into a secondary oocyte prior to ovulation
The primary follicle develops from the
primordial follicle
The principal hormone secreted by the corpus luteum is
progesterone
the corpus luteum will resume estrogen secretion and begin secreting
progesterone (controls second half of menstrual cycle)
During the luteal phase of the ovarian cycle, __________.
progesterone secretion by the corpus luteum stimulates endometrial growth and secretion
The secretion of estrogen causes
regrowth of the functional layer of the endometrium
Follicular phase of menstruation
rise in FSH causes maturation of follicles in ovarian cortex
perimetrium
serosa continuous with broad ligament
functional layer of endometrium
sloughed off during menses
If fertilization of the secondary oocyte occurs,
the embryo begins development within the uterine tube and then implants into the endometrium
menarche
the first menstrual period
Fertilization of an ovum usually takes place in the
uterine tube
basal layer of endometrium
where endometrium rethickens
The embryo secretes ____________ ___________, and analog of LH that maintains the corpus luteum
Chorionic Gonadotropin
Which is true regarding menses?
It marks the beginning of the uterine cycle
Rupture of the mature follicle is triggered by
a feedback mechanism causing a large surge of luteinizing hormone
oogonia are the germ cells that by the time of birth,
differentiate into primary oocytes that will undergo meiosis
Theca of the secondary follicle is involved in
endocrine signaling and once matured, secretes inhibin
primary follicle
enlarged primary oocyte surrounded by 1 or more layers of granulosa cells
Maturing follicle increases secretion of
estrogen
developing oocytes are housed in
ovarian follicles
endometrium
inner lining of the uterus
myometrium
involved in parturition; undergoes cell growth and cell division during pregnancy
The thick muscular layer of the uterus is the
myometrium
