Which of these hormonal axes coordinates human -female reproduction? a, anterior pituitary, posterior -pituatory ovaries.
00:10
B, hypothalamus anterior -pituatory uterus.
00:13
C, hyperthalamus posterior -poutuitary ovaries.
00:17
D, hyperthalmus anterior -pituatory ovaries.
00:20
Or e, hyperthalmus, posterior -pouturus.
00:25
Okay, so this is a particular axis, which is more generally called the hyperthalmus, pituitary gonadal axis.
00:37
So the hyperphalmus is first.
00:39
The hyperphalmus releases gonadotropin secreting hormone, releasing hormone.
00:50
So gnh, gnrh, is released from the hyperphalmus, and then it acts on the pituitary, and it specifically acts on the anterior vituatory.
01:04
So in response to gnh, gnrh, the anterior pituitary secretees luteinising hormone and follicle -stimulating hormone.
01:16
And those act on the gonads, and they produce estrogen in this case, because we're looking at the female reproductive system.
01:25
So from that, the answer is d, it's the hypothalamus, then the anterior pituitary, and then the ovaries, because those are the gonads in the females...
