Example Questions
Example Question #393 : Systems Physiology
Which of the following hormones is not involved in the menstrual cycle?
Estrogen
Prolactin
Follicle-stimulating hormone (FSH)
Luteinizing hormone (LH)
Progesterone
Prolactin
Prolactin is a hormone responsible for the production of milk in the mammary glands of mammals. It is not involved in the menstrual cycle, which is controlled by fluctuating levels of the hormones estrogen, progesterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH).
Example Question #394 : Systems Physiology
Which of the following can be defined as the process by which sperm is discharged from the male body?
None of these
menstruation
Oogenesis
Spermatogenesis
Ejaculation
Ejaculation
Ejaculation is defined as the process by which sperm is discharged from the male body through the urethra. This process typically occurs during the male orgasm.
Example Question #394 : Systems Physiology
Which of the following correctly identifies the typical—average—length of a single female menstrual cycle?
One average, one menstrual cycle typically lasts for about 28 days; however, this time length can range anywhere from 21 to 35 days depending on the individual.
Example Question #395 : Systems Physiology
What hormone causes ovulation to occur during the menstrual cycle?
Luteinizing hormone
Thyroid-stimulating hormone
Growth hormone
Prolactin
Follicle-stimulating hormone
Luteinizing hormone
An increase in estrogen causes an increase in the luteinizing hormone. It is the luteinizing hormone that causes ovulation. Ovulation is the process of releasing an ovum.
Growth hormone creates growth in the body. Follicle-stimulating hormone helps follicles mature, and promotes spermatogenesis in males. Prolactin causes the mammary glands to create milk. Thyroid-stimulating hormone helps release thyroxine and triiodothyronine (thyroid hormones).
Example Question #396 : Systems Physiology
Which of the following is true regarding the association between intercurrent diseases and pregnancy?
These diseases do not impact the pregnancy
The diseases can worsen as a result of the pregnancy
They are not pre-existing
Drugs taken to treat the disease have no impact on the fetus
None of these
The diseases can worsen as a result of the pregnancy
Intercurrent diseases are diseases that are not related to being pregnant (they were pre-existing) but may worsen during pregnancy. These diseases pose a risk to the developing fetus and special attention needs to be given to the drugs taken to treat the exiting illness because they may negatively impact the fetus. In the case of infections, there is a risk of vertical transmission to the fetus.
