Explain two reasons why a woman with low levels of LH would not be able to become pregnant.
-correct answers (1) LH acts on the ovary to cause ovula on to occur. (2) LH causes
progesterone release to facilitate poten al fer liza on of the egg and pregnancy. Progesterone
is a key hormone for the maintenance of pregnancy.
Would you expect a female to have testosterone in their bloodstream? Explain why or why not.
-correct answers (1) Yes. Both male and female bodies produce "all" the sex hormones.
However, the ra os are different. (2) The adrenal glands are largely responsible for producing
this "opposite" hormone that the ovaries would not.
Label the endocrine glands (A-D) A: ______________ B: ______________ C: ______________
D: ______________ -correct answers A: Thyroid gland B: Adrenal gland C: Kidney D: Pancreas
3. Label the endocrine glands (A-C) -correct answers A: Pineal gland B: Hypothalamus C:
Pituitary gland
Explain the concept of nega ve feedback and how it helps to maintain homeostasis. -correct
answers 1- The effect or increased level of the hormone acts to shut down the con!nued release
of the hormone. 2- The brain is constantly monitoring hormone levels to keep levels within a
certain range or set-point (homeostasis). Nega!ve feedback is a way of "turning off" hormone
produc!on when the desired level is achieved
4. Explain the concept of posi ve feedback. Give an example of a hormone that works through
posi ve feedback. -correct answers 1- Posi ve feedback is the ac on of a hormone increasing
the produc on of that hormone. (This is the opposite of nega ve feedback). 2- One example is
the ac on of oxytocin causing the uterus to contract during labor. Oxytocin enhances the effect
, of the uterus contrac ons, causing more oxytocin to be released. The posi ve feedback loop is
stopped once the baby is born and the uterus no longer needs to contract, stopping the
produc on of oxytocin.
