Reproductive Endocrinology Flashcards
what are the 3 nuclei that directly influence reproduction
surge center
tonic center
PVN
what hormones are released by the surge center
GnRH
peptide
what does the surge center target
anterior pituitary gland
what does GnRH cause the release of
gonadotropins
what hormone is released by the tonic center
GnRH
what does the tonic center target
anterior pituitary
tonic center release pattern
basal
surge center release pattern
episodic
what hormones does the PVN produce
oxytocin
vasopressin
peptides
what location does PVN target
posterior pituitary
anterior pituitary
adenohypophysis
posterior pituitary
neurohypophysis
hypophysis
describes the location of the gland relative to the brain
brain tissue
infundibulum
esophagus tissue
Rathke’s pouch
what are the hormones of the anterior pituitary
prolactin (PRL)
growth hormone (GH)
adrenocorticotropic hormone (ACTH)
thyroid stimulating hormone (TSH)
follicle stimulating hormone (FSH)
luteinizing hormone (LH)
what hormones make up gonadotropins
FSH and LH
what do the gonadotropins target
gonads
what hormones of the anterior are peptides
PRL
GH
ACTH
TSH
which hormones of the anterior are glycoproteins
FSH
LH
what is the function of the posterior pituitary
- storage closet
- stores hormones produced in PVN
what tissue makes up the posterior
nervous
negative sign
inhibit or negative feedback
positive sign
- stimulate
- positive feedback
what hormone contains inhibin
glycoproteins
what hormones do steroids contain
progestogens
androgens
estrogen
what location synthesizes cholesterol
smooth ER
how many carbons does cholesterol have
27
where are steroids created
mitochondria
what is the carrier protein that carries cholesterol from smooth ER to mitochondria
StAR
how many carbons does the enzyme P450SCC remove off the cholesterol
6
what type of feedback is not good
positive
