Question 2
As described in Chapter 4, the various brain structures and other biological factors operate according to a feedback loop in order to regulate the menstrual cycle. Which of the following students provides the best description of this feedback loop?
a. Dakwan: When the level of a hormone is too high, a structure in the brain is signaled to inhibit hormone production; when the level is too low, the brain structure is signaled to produce more hormones..
b. Angus: When the hypothalamus is signaled, a follicle in the hypothalamus releases an egg; when the hypothalamus is not signaled, the follicle does not release the egg..
c. Sandi: When a female reaches puberty, her endometrium signals the pituitary gland, which varies in size, depending on the menstrual cycle; for instance, the pituitary gland is largest at the time of ovulation..
d. Adriana: When a female has her period, the menstrual flow signals the hypothalamus, which inhibits the development of the follicle..
