LH leads to
Ovulation
Secondary oocyte is fertilized in
Fallopian tube
Corpus luteum releases
Progesterone
What triggers ovulation
LH surge
If you block effects of estrogen days 5-9 you block - feedback and have more
LH and FSH (to have ovulation)
If you block effects of estrogen days 10-13 you block + feedback but you don’t want to do this because you
Want more LH (don’t want to block)
Have more Na+
Outside
Have more K+
Inside
Cl- in action potential is
Equal on outside and inside
Amplitude vs frequency
You will not get higher action potential (amplitude) but more (frequency)
Calcium channels allow for release of
