Female Reproductive HW
Place the following terms in order of the ovarian cycle
- Primordial follicle - Primary follicle - Secondary follicle - Mature follicle - Ovulation - Corpus Luteum - Corpus Albicans
Check all that are normal functions of the uterine tubes - site for implantation of the pre-embryo - transport the oocyte to the uterus - site for fertilization - provide nourishment to the developing embryo
- transport the oocyte to the uterus - Site for fertilization
Put the stages of follicle development into the correct order, beginning with the earliest structure that develops
1. Primordial follicle 2. Primary follicle 3. Secondary follicle 4. Antral follicle 5. Mature follicle 6. Corpus luteum 7. Corpus albicans
Match each hormone with its associated event in the ovarian cycle Produced by growing follicle
Estrogen
Match the hormone with its effect on the ovary, uterus, or oogenesis Causes development of functional layer of uterus
Estrogen
Match the hormone with the anatomical structure that releases the hormone Released by developing ovarian follicle
Estrogen
The hormone prolactin is released from the posterior pituitary gland to cause milk ejection following birth or parturition. TRUE OR FALSE
FALSE
The secretory phase of the uterine cycle occurs at the same time as the follicular phase of the ovarian cycle TRUE OR FALSE
FALSE
During the follicular stage, local growth factors and _______ from the anterior pituitary stimulate development of an ovarian follicle, which produces estrogen and a small amount of progesterone.
FSH
Match each hormone with its associated event in the ovarian cycle Aids in follicular development, along with local growth factors
FSH
Match the hormone with the anatomical structure that releases the hormone Released from anterior pituitary
FSH/LH
Along with local factors, growth of follicles and resulting secretion of estradiol are dependent on ___________ , while the surge in ____________ at the end of the follicular phase is responsible for ovulation.
FSH; LH
Match the phases of the ovarian cycle with their descriptions Primary follicles develop into secondary follicles; one follicle becomes a mature follicle
Follicular phase
Match the hormone with the anatomical structure that releases the hormone Released from hypothalamus
GnRH
A spike in estrogen levels also causes a sudden secretion of a large amount of _________ from the hypothalamus, leading to a surge of LH, which causes __________ at about the 14th day of a 28-day cycle.
GnRH; ovulation
Match the hormone with its effect on the ovary, uterus, or oogenesis Causes inhibition of FSH production
Inhibin
3. Sloughing off of the stratum functionale of the endometrium occurs
Menstrual phase
Match the phases of the ovarian cycle with their descriptions A secondary oocyte is released from the ovary and enters the uterine tube
Ovulation
Match each hormone with its associated event in the ovarian cycle Produced uniquely by corpus luteum
Progesterone
Match the hormone with its effect on the ovary, uterus, or oogenesis Involved in secretory phase of uterine cycle
Progesterone
Match the hormone with the anatomical structure that releases the hormone Released by corpus luteum after ovulation
Progesterone
Occurs while the ovary is in its follicular phase; estradiol stimulates growth of the stratum functionale of the endometrium
Proliferative
2. Occurs while the ovary is in its luteal phase; the endometrium becomes thick and more vascularized
Secretory phase
Ovaries and testes produce gametes TRUE OR FALSE
TRUE
The uterus serves as the site of implantation for the embryo, supports the developing embryo, and contracts during birth to expel the fetus. TRUE OR FALSE
TRUE
If fertilization does not occur, the corpus luteum becomes a
corpus albicans
During the luteal phase, LH promotes the development of the _____________, which secretes estrogen and progesterone.
corpus luteum
During ovulation, the ________ ruptures and the oocyte enters the uterine tube; later, the empty follicle undergoes structural and biochemical changes and a __________ is formed.
follicle; corpus luteum
Gonadotropin releasing hormone is released by the
hypothalamus
Trace the path of an egg would take through the female reproductive tract
ovary, uterine tube, uterus, vagina
A female is born with approximately 1.5 million _____ follicles, and these are the only follicle type that develops before puberty.
primordial
Decreasing levels of ____________ lead to sloughing, or shedding, of the endometrial lining.
progesterone
Milk production is controlled by the hormone ____ while milk ejection is controlled by the hormone ____.
prolactin; oxytocin
Ovulation involves the release of the _____________ from a mature follicle.
secondary oocyte
In females, the ovaries are paired, oval organs located within the pelvic cavity lateral to the
uterus
Which are produced by male and female gonads? Select all that apply. - Gametes - Sex hormones - Accessory reproductive organs - Coitus
- Gametes - Sex hormones
Place the following layers of the uterus in order from superficial to deep (outside to inside)
- Perimetrium - Myometrium - Endometrium - Uterine Cavity
Drag each of the terms or statements in the proper category to identify whether the given label refers to an item or process that occurs prior to or after ovulation. Assume fertilization was successful - Second meiotic division completion - Second meiotic division begins - Second polar body formation - Corpus Luteum - Primordial follicless - Mature follicle - First polar body formation - First meiotic division
BEFORE OVULATION - Primordial follicles - First polar body formation - Mature follicle - First meiotic division - Second meiotic division begins AFTER OVULATION - Corpus Luteum - Second polar body formation - Second meiotic division completion
Drag each of the terms or statements in the proper category to identify whether the given label refers to an item or process that occurs prior to or after ovulation. Assume that the ovulation occurs on day 14 and unless specifically stated, assume fertilization was unsuccessful.
BEFORE OVULATION - proliferative phase of uterine cycle - rapidly rising LH - estrogen low - rapidly rising FSH AFTER OVULATION - progesterone peak - rapidly declining gonadotropins - secretory phase of uterine cycle - menses
Match each hormone with its associated event in the ovarian cycle Induces ovulation
LH
Match the hormone with its effect on the ovary, uterus, or oogenesis Causes ovulation of the mature follicle
LH
The increasing amount of progesterone in the blood inhibits secretion of ________ by the anterior pituitary, and the luteal phase comes to an end.
LH
Match the phases of the ovarian cycle with their descriptions 3. The empty follicle becomes a corpus luteum, which secretes estradiol and progesterone
Luteal phase
What structure is highlighted?
endometrium
As the levels of progesterone and estrogen in the body are reduced, _______________ begins.
menstruation
The __________ ovarian cycle can be divided into follicular and luteal phases.
monthly
High levels of estrogen in the blood exert ___________ feedback control over the anterior pituitary to stop the release of FSH and to halt the follicular phase of the ovarian cycle.
negative
