What is an appropriate definition of attaining puberty in female domestic animals (more than one answer)
- hypothalamus surge centre responds to high estradoil levels with LH pulses of amplitude and frequency capable of inducing ovulation
- ovulation of a fertilizable oocyte
- formation of a viable corpus luteum
- attainment of a threshold body size of half the predicted mature body weight
- hypothalamus surge centre responds to high estradoil levels with LH pulses of amplitude and frequency capable of inducing ovulation
- ovulation of a fertilizable oocyte
- formation of a viable corpus luteum
which of the following statements concerning the uterine tubes are correct?
- the ampulia has a very convoluted lumen
- they have ciliated and secretory cells whose number and activity are infleunced by the stage of the oestrous cycle
- they consist of only 2 sections: infundibulum and isthmus
- they are suspended by the mesoalpinx
- the ampulia has a very convoluted lumen
- they have ciliated and secretory cells whose number and activity are infleunced by the stage of the oestrous cycle
- they are suspended by the mesoalpinx

- it contains the broad ligament
- it contains variable amounts of fat
- it contains the ovarian artery
- it contains the ovarian vein
- it contains variable amounts of fat
- it contains the ovarian artery
- it contains the ovarian vein
corona radiata comprised of granulosa (also called cumulus) cells
what is F and its function
uterine horn - support and nourish the foetus
what is C
the uterine body
Prostaglandin F has general action on ___ muscle cells and a specific action within the reproductive tract in cells in the ___ and ____
- Smooth muscle cells (involuntary)
- uterus
- ovary (corpus luteum, endometrium etc.)
What receptors on the endometrial cell membranes enable release of prostaglandin F from endometrial cells?
- oxytocin receptors
in high producing dairy cows, luteal insufficiency is known to be associated with lower pregnancy rates. which of the following would be most significant contributor to those lower pregnancy rates?
- reduced numbers of GnRH receptors in the pituitary
- reduced numbers of endometrial oxytocin receptors
- reduced endometrial gland secretion
- reduced myometrial contractility
- reduced endometrial gland secretion
which of the following is most essential to create an environment suitable for folliculogenesis?
- FSH stimulates aromatase activity in growing follicles to increase estradiol levels within the follicle antrum
- upregulation of FSH receptors on granulosa cells to convert dihydrotestosterone into estradiol
- similar concentrations of progesterone within the follicle antrum and in systemic circulation
- downregulation of LH receptors on granulosa cells
FSH stimulates aromatase activity in growing follicles to increase estradiol levels within the follicle antrum
What is required for an animal to enter puberty?
increased GnRH pulse frequency from the hypothalamus, stimulates the anterior pituitary to release high levels of FSh and LH
Follicle stimulating hormone FSH is used as a fertility drug to ‘super ovulate’ adult females. what would be the most likely result i FSH was administered to a 6 week old lamb?
- stimulation of follicle development and growth of multiple large antral follicles
What species are these from
Cow, ewe and then mare - ewe has extensive cervical rings - cow has deep folds - mare had loose mucosal folds and easy passage
