Question 1
pts
Explain two reasons why a woman with low levels of LH would not be able to
become pregnant.
(1) LH acts on the ovary to cause ovulation to occur.
(2) LH causes progesterone release to facilitate potential fertilization
of the egg and pregnancy. Progesterone is a key hormone for the
maintenance of pregnancy.
*Luteinizing hormone (LH), ovary, ovulation
Question 2
pts
Would you expect a female to have testosterone in their bloodstream? Explain why or why not.
(1) Yes. Both male and female bodies produce “all” the sex hormones. However,
the ratios are different.
(2) The adrenal glands are largely responsible for producing this “opposite”
hormone that the ovaries would not.
Would you expect a male to have estrogen in their bloodstream? Explain why or why not.
Yes because male and female bodies produce all the sex hormones their ratios
are just different. The adrenal glands are largely responsible for producing this
opposite hormone that the testis wouldn't
Question 4
pts
Explain the concept of negative feedback and how it helps to maintain homeostasis.
1- The effect or increased level of the hormone acts to shut down the continued
release of the hormone.
2- The brain is constantly monitoring hormone levels to keep levels
within a certain range or set-point (homeostasis). Negative feedback is a way of
“turning off” hormone production when the desired level is achieved
Explain the concept of positive feedback. Give an example of a hormone that works
through positive feedback.
Positive feedback is the action of a hormone increasing the production of that
hormone. 2- One example is the action of oxytocin causing the uterus to
contract during labor. Oxytocin enhances the effect of the uterus
contractions, causing more oxytocin to be released. The positive feedback
loop is stopped once the baby is born and the uterus no longer needs to
contract, stopping the production of oxytocin.
