Example Question #41 : Understanding Other Reproductive Physiology
Which of the following characteristics is true regarding follicle development in the ovaries?
Only one follicle develops per menstrual cycle
Multiple follicles develop and release oocytes each menstrual cycle
Genetic damage causes all other follicles to arrest development, allowing the dominant follicle to form
There are competing follicles and hormones that promote the development of the dominant follicle
There are competing follicles and hormones that promote the development of the dominant follicle
During the follicular phase of the menstrual cycle, follicle-stimulating hormone (FSH) stimulates the development of multiple follicles. The follicles compete with each other and the most developed follicle becomes the dominant follicle. The dominant follicle will release an oocyte during ovulation.
Example Question #42 : Understanding Other Reproductive Physiology
Which of the following best describes what happens to an egg cell if it does not get fertilized by a sperm cell in humans?
It implants and is eventually expelled from the body
It disintegrates and is expelled from the body
It returns to the ovary
It remains in the fallopian tube
It disintegrates and is expelled from the body
Oocytes are released from the dominant follicle and travel down the fallopian tube. If the oocyte is not fertilized, it will disintegrate and be expelled from the body by way of menstruation.
Example Question #43 : Understanding Other Reproductive Physiology
Which of the following best describes what the corpus luteum develops from in female humans?
The dominant follicle
An unfertilized oocyte
The fimbria of the fallopian tube
The non-dominant follicles
The dominant follicle
The corpus luteum is a structure in female humans that develops from the dominant follicle after ovulation. The corpus luteum is involved in the endocrine system and it secretes progesterone to maintain the endometrial lining if the released oocyte is fertilized. If the oocyte is not fertilized, it stops secreting progesterone, causing the shedding of the endometrial lining and degeneration of the corpus luteum.
Example Question #44 : Understanding Other Reproductive Physiology
Which of the following hormones is secreted by the corpus luteum and helps to build up the endometrial lining?
Luteinizing hormone (LH)
Estrogen
Follicle-stimulating hormone (FSH)
Progesterone
Progesterone
The corpus luteum develops from the dominant follicle after ovulation. It secretes progesterone to build up the endometrial lining and promote oocyte implantation. If the oocyte does not get fertilized, then the corpus luteum stops secreting progesterone. This causes the degeneration of the corpus luteum and menstruation.
Example Question #45 : Understanding Other Reproductive Physiology
Which of the following best describes the correct order of stages in the ovarian cycle of the menstrual cycle?
Luteal phase, ovulation, and follicular phase
Follicular phase, ovulation, and luteal phase
Follicular phase, luteal phase, and ovulation
Ovulation, luteal phase, and follicular phase
Follicular phase, ovulation, and luteal phase
The menstrual cycle is the development of the female reproductive system for potential pregnancy. The cycle can be divided into two parts—the ovarian cycle and the uterine cycle. The ovarian cycle has three phases—the follicular phase, ovulation, and the luteal phase.
Example Question #46 : Understanding Other Reproductive Physiology
Which of the following is true regarding female women post menopause?
They ovulate once per month
They exhibit increased fertility due to a higher oocyte release rate
There is a cessation of ovulation and fertility
They have a thick endometrial lining
There is a cessation of ovulation and fertility
Menopause is a stage when female humans stop ovulating and menstruating; therefore, they can no longer have children. Menopause typically occurs between 45 to 55 years. Common symptoms include hot flashes, vaginal dryness, and mood changes. Menopause occurs due to the end of estradiol and progesterone production by the ovaries.
Example Question #47 : Understanding Other Reproductive Physiology
Which of the following is not an example of surgical menopause?
Removal of the fallopian tube(s)
Removal of the ovaries
Removal of the uterus
Removal of the breasts
Removal of the breasts
Surgical menopause is a process in which a surgical procedure induces menopause. The procedures that do this are an oophorectomy (removal of the ovaries), hysterectomy (removal of the uterus), and salpingo-oophorectomy (removal of the fallopian tubes). These surgeries create a decrease in hormone levels that bring about menopausal symptoms.
Example Question #48 : Understanding Other Reproductive Physiology
Which of the following is not true regarding the role of progesterone in the luteal phase?
A drop in the concentration of progesterone leads to menstruation
High concentrations of progesterone stimulate FSH and LH secretion
It is secreted by the corpus luteum
High concentrations of progesterone inhibit FSH and LH secretion
High concentrations of progesterone stimulate FSH and LH secretion
During the luteal phase of the ovarian cycle during the menstrual cycle, progesterone levels can either maintain pregnancy or prepare the female human for menstruation. High FSH (follicle-stimulating hormone) and LH (luteinizing hormone) levels stimulate the formation of the corpus luteum from the follicle. The corpus luteum then secretes progesterone. In a negative feedback loop, the high levels of progesterone inhibit FSH and LH production, degrading the corpus luteum. The drop in progesterone levels leads to menstruation.
Example Question #131 : Reproductive System
Which of the following best describes what happens to the corpus luteum when the oocyte is fertilized?
It degrades into the corpus albicans
It is maintained by estrogen
It travels down the fallopian tube
It is maintained by human chorionic gonadotropin (hCG)
It is maintained by human chorionic gonadotropin (hCG)
After the oocyte is fertilized, the outer layers of the blastocyst secrete human chorionic gonadotropin (hCG). The hCG stimulates the corpus luteum to keep secreting progesterone in order to maintain a thick endometrial lining to support the developing embryo.
Example Question #1325 : Ap Biology
Which of the following symptoms accompanies ovulation in some women?
Nausea
Abdominal cramps
Vomiting
Hot flashes
Abdominal cramps
In some women, ovulation is accompanied by abdominal cramping. The pain is typically sudden and lasts no more than a few days.
