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

30

FSH, LH, TSH, hCG, CRH, ADH (V2), MSH, PTH use this signaling pathway

cAMP
