6. which pituitary communicates w hypothalamus with Hormones transported via axons of hypothalamic neurons and then stored in posterior pituitary
posterior
anterior
7. ACTH release from anterior pituitary going to adrenal cortex and stimulating adrenal cortex which releases glucocorticoids which have an array of functions: select INCORRECT one
increase rate of protein catabolism & lipolysis
decreases glucose levels
anti-inflammatory effects reduced
help regulate metabolism
conversion of amino acids to glucose
8. WHAT stimulates release of GHRH from hypothalamus
anterior pituitary releases more hGH, more glycogen broken down into glucose by liver cells
low blood sugar
high blood sugar
9. 2 large classes of hormones are lipid-soluble and water-soluble, one uses transport proteins and the other circulates in its 'free' form. which is the first (transport proteins)
lipid soluble
water soluble
10. nervous and endocrine system, one has slow responses effects last longer, broader influence. and the other Faster responses, briefer effects, acts on specific target. which is the latter (faster)
nervous
endocrine
11. two types of control of hormone secretion: negative and positive feedback control. which one's effect prevents any further hormone secretion
13. Endocrine glands include pituitary and hypothalamus. which of the two entails thymus, pancreas, ovaries, testes, kidneys, stomach, liver, small intestine, skin, heart, adipose tissue, and placenta not exclusively endocrine glands
hypothalamus
pituitary
14. the 2 hormones of POSTERIOR PITUITARY are Oxytocin and ADH. Oxytocin's main Two target tissues both involved in neuroendocrine reflexes are WHAT?
uterus AND mammary glands
Ovary and testis
Liver, adipose tissue
15. water soluble hormones (here hormone receptors are integral membrane proteins acting as FIRST MESSENGERS): select CORRECT sequence
Adenylate cyclase converts ATP into cyclic AMP which activates protein kinases.
Protein kinases phosphorylate enzymes which catalyze reactions that produce the physiological response.
The activated receptor activates a membrane G-protein which turns on adenylate cyclase.
The activated receptor activates a membrane G-protein which turns on adenylate cyclase.
The hormone binds to the membrane receptor.
enylate cyclase converts ATP into cyclic AMP which activates protein kinases.
Protein kinases phosphorylate enzymes which catalyze reactions that produce the physiological response.
The hormone binds to the membrane receptor.
The activated receptor activates a membrane G-protein which turns on adenylate cyclase.
Adenylate cyclase converts ATP into cyclic AMP which activates protein kinases.
Protein kinases phosphorylate enzymes which
The activated receptor activates a membrane G-protein which turns on adenylate cyclase.

16. major target organs for Luteinizing hormone and Follicle-stimulating hormone
Uterus and mammary glands
Liver, adipose tissue
ovary and testis
Mammary gland
17. autocrine works on what
act on the same cell that secreted them
act on neighbouring cells
18. It acts indirectly on tissues (liver, skeletal muscle, cartilage and bone) by promoting the synthesis and secretion of small protein hormones called what?
insulin-like growth factors (IGFs)
Adrenocorticotrophic Hormone
19. overactivity of growth hormone- Somatostatin analogue. More potent that SOM in terms of inhibiting GH release
Somatropin
Octreotide
Mercasermin
Somatostatin
20. all hormones come from pituitary, but related by what what control
