a. norepinephrine secretion
b. epinephrine secretion
c. testosterone secretion

hormone (TSH) would indicate that
a. the negative feedback mechanism is not working
b. the negative feedback mechanism is working
c. too much thyroxine is being secreted
d. none of the above
How does testosterone secretion affect luteinizing hormone (LH) secretion?

9 / 10

10. Question 2)
c. Too much thyroxine is being secreted
this occurs because an agonist is sitting in the receptor that stimulates thyroxine secretion..
Thus it is being over activated!!
Question 3)
LH stimulates the secretion of testosterone from the leydig cells
