1
hormones produced by basophils of anterior pituitary
FSH, LH, ACTH, TSH
("B-FLAT")
2
hormones produced by acidophils of anterior pituitary
GH, PRL
3
GLUT 1 found in
RBCs, brain, cornea, placenta
4
GLUT 2 found in
islet cells, liver, kidney, small intestine. it's bidirectional
5
GLUT 3 found in
brain, placenta
6
GLUT 4 found in
adipose tissue, striated muscle. This is the only one that is insulin dependent
7
GLUT 5 found in
spermatocytes, GI tract. used for fructose
8
insulin receptors are of which class
tyrosine kinase
9
effect of insulin on Na+
increases retention in kidneys
10
effect of TRH
increases TSH and prolactin
11
effect of somatostatin on pituitary
decreases GH and TSH
12
effect of dopamine on pituitary
decreases prolactin and TSH
13
effect of PRL on hormone release
decreases GnRH
14
ADH acts on vessels via which receptor
V1
15
ADH acts on kidneys via which receptor
V2
16
17-hydroxylase def: effects on BP, cortisol, and sex hormones
increased BP
decreased sex hormones and cortisol
17
21-hydroxylase def: effects on BP, cortisol, and sex hormones
increased sex hormones
decreased BP and cortisol
18
11-hydroxylase def: effects on BP, cortisol, and sex hormones
increased sex hormones and BP
decreased cortisol
19
labs 17-hydroxylase deficiency
decreased androstenedione
20
labs 21-hydroxylase deficiency
increased renin, increased 17-hydroxyprogresterone
21
labs 11-hydroxylase deficiency
decreased renin
22
ACTH activates
cholesterol desmolase to form pregnenolone
23
physiologic effects of vitamin D
increases gut absorption of Ca and phosphate
24
which cells produce PTH
chief cells of parathyroid
25
effect of moderately low Mg2+ on PTH release
increases
26
effect of extremely low Mg2+ on PTH release
decreases
27
which cells produce calcitonin
parafollicular (C cells) of thyroid
28
physiologic effects of calcitonin
mainly/only decreases bone resorption
29
BNP, ANP, EDRF (for NO) use this signaling pathway
cGMP
