GUARANTEED SUCCESS
An oogonium enters ____________ embryonically and is blocked at _____________ until
sexual maturity. Fill in the blanks. meiosis: diplotene I
In the ovary, oocytes are held at metaphase II of meiosis until fertilization. How is this block
released? A Ca2+ influx induces the activity of calmodulin, which induces Camodulin
dependent kinase (CAM PKII) and calpain and they degrade cystostatic factor (CSF).
If you have a defect that blocks the release of gonadotropin releasing hormone (GnRH) from
the pituitary, which of the following statements about folliculogenesis would be true? A lack
of GnRH would inhibit folliculogenesis.
During the menstrual cycle, there is an increase of __________ midcycle, which stimulates a
surge of __________ and induces the synthesis of progesterone by granulosa cells. Fill in the
blanks. estrogen; luteinizing hormone
Spermatozoa that are harvested directly from the epididymis for IVF in men with blockage of
their vas deferens are incompetent to fertilize eggs. What must first happen for successful
fertilization? capacitation
The acrosome reaction __________. Pick the best answer to finish the statement. releases
enzymes necessary for penetrating the zona pellucida
