What is the primary function of the ovaries?
To produce female gametes (oocytes) and hormones
Which structure in the ovary is responsible for the final stage of oocyte maturation?
Ovarian cortex
What is the primary role of estrogen secreted by the ovaries?
To stimulate the growth of the uterine lining
What is the function of the corpus luteum?
To produce progesterone and inhibin
Which hormone is responsible for triggering ovulation?
Luteinizing hormone (LH)
What is the role of the follicles in the ovary?
To support the development and maturation of the oocytes
What is the first stage of follicular development?
Primordial follicle
What triggers the final division of chromosomal material in the secondary oocyte, leading to the formation of a zygote?
Fertilization
What is the function of the corpus luteum?
To secrete progesterone
During which stage of the menstrual cycle does the corpus luteum form?
Ovulatory phase
What is the primary function of estrogen during the menstrual cycle?
To stimulate the growth of follicles
What is the main difference between oogonia and primary oocytes?
Oogonia are the precursors to primary oocytes, which develop during oogenesis
What is the primary function of the granulosa cells in the mature follicle?
To provide a blood supply to the follicular cells and deliver hormones
Which of the following is the correct sequence of events during oogenesis?
Primordial follicle > Primary oocyte > Secondary oocyte > Ovum
What is the primary role of the corpus luteum during the reproductive cycle?
To secrete progesterone and maintain the uterine lining
What is the main function of the zona pellucida surrounding the primary oocyte?
To allow sperm entry and fertilization
What is the primary function of the theca cells in the mature follicle?
To secrete estrogen in response to FSH
How do the levels of estrogen change during the menstrual cycle?
Estrogen levels increase during the follicular phase and decrease during the luteal phase
What is the primary function of the fimbriae at the end of the fallopian tube?
To sweep the secondary oocyte into the fallopian tube after ovulation
What is the primary role of the uterine tube (fallopian tube) in the reproductive process?
To transport the secondary oocyte from the ovary to the uterus
What is the main function of the corpus luteum after ovulation?
To secrete progesterone and maintain the uterine lining
How does the presence of the corpus luteum affect the levels of estrogen and progesterone during the menstrual cycle?
The corpus luteum increases the level of progesterone and decreases the level of estrogen
Learn about the process of ovulation and fertilization, including the formation of secondary oocytes, completion of meiosis, and the formation of a zygote upon fertilization. Understand how primary oocytes develop into mature eggs during the reproductive cycle.
