TRH produced in what nuclei?
Somatostatin produced in what nuclei?
Name 2 hypothalamic releasing hormones manufactured in the PVN
CRH and TRH
Does prolactin have a hypothalamic releasing factor?
No. It's under tonic inhibitory control of dopamine.
Under pathological conditions, excessive TRH can stimulate
Prolactin is a potent inhibitor of

AVP-secreting magnocellular neurons are derived from what brain nuclei?
SON and PVN
AVP-secreting parvocellular neurons are derived from what brain nucleus?
What are the two divisions of the PVN?
Magnocellular and parvocellular
AVP-secreting magnocellular neurons regulate

What happens to the zona fasciulata under exogenous corticosteroid treatment (long-term)
What's the precursor gene for ACTH and alpha-MSH
Small cell lung carcinomas can secrete
Kd refers to hormone affinity or specificity to receptor?
Receptor kinases versus receptor linked kinases
Receptor kinases have intrinsic kinase activity; linked don't.
Name hormones that bind receptor-linked kinases (3)
Name hormones that bind regular receptor kinases (3)
Recite the melatonin synthesis pathway
Tryptophan to 5-HTP via tryptophan hydroxylase (RLS). 5-HTP to 5HT. 5HT to melatonin through N-acetyltransferase (RLS for melatonin, in PINEAL gland).
Recite the dopamine synthesis pathway
...tyrosine hydroxylase (RLS)....
2. X-Dopa (L-Dopa is active)
...dopamine B-hydroxylase (ACTH promotes)...
...PMNT (cortisol promotes)...
