The presence/ absence of this hormone is used in antibody based pregnancy tests.
hcG
100
Progesterone is secreted by the ______ cells in the _____ ____.
Granulosa cells, Corpus luteum
100
FSH/ LH secretion is directly stimulated by what hormone?
GnRH
100
 Prostaglandin secretion from the endometrium in response to progesterone affects what tissue?
Corpus Luteum
100
Suckling initiates oxytocin release, what then does oxytocin do? Be specific.
Milk let down by contraction of myoepithelial layer of alveoli in mammaries.
200
This hormone is responsible for maintaining the endometrium.
Progesterone
200
Estrogen is partly made in the thecal cells and then secreted from what type of cells?
Granulosa Cells
200
GnRH secretion is directly stimulated by neuronal mechanisms and what else?
Kisspeptin neurons from AVPV and Arcuate nuclei
200
Release of NO from endothelial cells and NANC neurons cause relaxation of _______ in _______.
arteriolar smooth muscle, gential vasculature
200
LH surge and the progesterone bump do what?
Activates proteases in the follicle to eat away at the exit allowing the primary oocyte to ovulate.
300
In males, the pulsatile secretion of this hormone causes a constant secretion of testosterone.
LH
300
hcG is secreted from ________?
Syncytiotrophoblast cells
300
A rise in estrogen during cyclic recruitment is caused by three things what are they?
FSH induced proliferation of numbers of granulosa cells, Activin and inhibin stimulating Estrogen synthesis by granulosa cells, and estrogen induced estrogen release from granulosa cells.
300
_______ activates the JAK STAT pathway in alveolar cells of _______.
Prolactin, Mammary epithelium
300
Secretion of fetal cortisol produces a reduction in local activity of this hormone, also what does this allow to happen?
Progesterone, onset of labor (progesterone quiets the uterine smooth muscle)
400
This hormone binds to a GPCR, and is mainly responsible for the large increase in size of the follicle during cyclic recruitment.
FSH
400
Oxytocin is a peptide hormone secreted from where? Is it synthesized in this location?
Posterior Pituitary, no
400
What action stimulates prolactin secretion via hypothalamic neural pathways?
Suckling
400
 With the onset of labor, high levels of estrogen increase the expression of ______ receptors in what tissue?
Oxytocin, uterine smooth muscle
400
 PLC is released from sperm that just fused with an egg. What happens?
An Influx of Calcium changes the egg's membrane to be impermeable to sperm cells. Resume meiosis 2 from being paused in metaphase 2.
500
 This hormone has to major roles, it binds to a Gq GPCR and results in the activation of Pip2, IP3, and DAG pathway. IP3 causes the release of Ca from the Sarcoplasmic reticulum, and DAG goes on to activate PKC which then activates PLA2 releasing Arachidonic acid which is then converted to _________. What is the hormone and what word goes in the blank?
Oxytocin, prostaglandins
500
Name four possible locations in which prostaglandins can be found.
Endometrium, uterus, placenta, fetal membranes
500
What structure acts as a mechano receptor stimulating the secretion of oxytocin through a reflex? What is the name of the that reflex?
Cervix, Ferguson Reflex
500
Prostaglandins promote the formation of gap junctions in what tissue? Why is this important?
Uterine smooth muscle, contraction teamwork
500
 What is the proposed mechanism of the contraceptive, "Mirena" (progestin).
Premature capacitation of sperm through Catsper channel.
