Physiology Flashcards
1
Q
what are the two parts to the pituitary?
A
anterior
posterior
2
Q
hormones produced by the anterior pituitary
A
ACTH TSH GH PRL FSH/LH MSH
3
Q
hormones produced in the posterior pituitary
A
ADH
oxytocin
4
Q
where are the two portal systems in the body?
A
liver
pituitary
5
Q
two categories of hypothalamic hormones
A
releasing inhibiting (somatostatin-GH and dopamine- PRL) all are peptides, except dopamine
6
Q
three potential reasons for an endocrine presentation
A
too much hormone
too little hormone
gland is too big
7
Q
how can hormone amounts by diagnosed?
A
blood tests
8
Q
how can gland size by diagnosed
A
imaging e.g. MRI/USS
9
Q
in embryology what is the anterior pituitary derived from?
A
Rathke’s pouch
10
Q
steroid (cortisol) axis
A
hypothalamus= CRH pituitary= ACTH peripheral= cortisol
11
Q
thyroid axis
A
hypothalamus= TRH pituitary= TSH peripheral= thyroxine
12
Q
sex hormone axis
A
hypothalamus= GnRH pituitary= LH/FSH peripheral= E2/TEST
13
Q
growth hormone axis
A
hypothalamus= GHRH pituitary= GH
14
Q
prolactin axis
A
hypothalamus= Dopamine (inhibitory) pituitary= reduced prolactin
15
Q
are the two hormones in the posterior pituitary (ADH and oxytocin) stored?
A
yes
