extra Flashcards
how is hormone availability controlled
- secretino
- activation
- bidnding of lipophilic hormones in plasma
- inactivation
is phosphorylatino for peptide or lipid hormones
peptide
when is signal amplification used
in CAMP second messenger systems
where are neurosecretory neuronal cell bodies
in hypothalamus (PVN and SO)
preprooxyphysin and preprovasopressin
the things produced from the large precursor by PVN and SO
what cuases vasocnonstriction in vascular smooth muscle to maintian blood pressure
vasopressin
secretion stimuli for ADH
hyperosmolarity
hypovolemia
low blood pressure in arteries
where are osmoeceptor neurons outside BBB
OVLT and SFO
WHERE are blood volume receptors for ADH
easily stretchable low pressure areas
large veins
heart atria
what does alcohol inhibit
ADH secretion
where do hormones enter circulatino into blood from the brain
hypothalamic- hypophyseal portal system
what do somatotropes produce
growth hormone
what do thyrotropes produce
TSH
what do corticotropes produce
ACTH
what do lactotropes procuce
prolactin
waht do gonadotropes produce
LH and FSH
three classes of homrones
amines
peptide
steroid
what part of the pituitary is hypothalic hypophysela portal system for
anteriro pituitary
where are peptide hormones produced
in rough ER
where are catecholaminse produced
in cytosol
where are thyroid hormones produced
in colloid
wehre are steroid hormones produced
from choleterol stepwise in various compartments
what hormones are stored in secretory granules
peptide
where are catecholamines stored
in choromaffin granules
