18
Q

example of non trophic

A

nerual hormes produe ni hypothalus travel to te to posterio pituatry though axons to release a chemical into blodd

19
Q

examples o ftropic hormoens

A

nueroal hormes secrete into capillarei travell to antiero pituary

20
Q

type of neruon in posterior pituatry

A

magnocelluar neurons

21
Q

role of magnocelluar hromes

A

release Peptie neuro hormones - vasopressing - anti diurectic hrome adh
oxytocin - stimalres uterine corntioact (during labour) and adis in exression of milk in locating brest

22
Q

role of oxytoicn and vasopressin in postieor prituatry

A

act like peptide hormes to pacakage and store the visible allowing its release

23
Q

how are postioer pituar hroemes transprt from hypotha

A

as veiscels so the poster ptiaury can erasle them into the blood after being stored

24
Q

what are the main 5 hypothalmic relases hormones

A

trh
crh - corticotropin releaseing hormone
ghrh
gnrh - gonadotropin relaasing hromone
prolactin releasing horomone

25
Q

what are the hypothalic inhibiting hormone

A

growth hormone inhibing horome
dopamine / prolactin inhibing hormone

26
Q

what are the type of horme are they

A

pepties , ext dopamine whihc is catecholamines

27
Q

what can thryoid regulaing hormoen stimular

A

tsh and prolacing

28
Q

what does ghih stop

A

g rotwh hrome reles

29
Q

what does dopamine stop

A

porlactain

30
Q

what is teh hypothalmo hypophyseal portal system

A

system of tiny vessels whihc tranfer tropic hormones from hypothalamus to antiero pituatary

31
Q

what are the anteior pituatary hormones

A

tsh
acth
fsh - follicle stimulating hormone
lh - luteising hormone
gh
prolactin

32
Q

what type of action is prolactin

A

it is direct acting thus not trophic

33
Q

what is long loop vs short loop feed back

A

long loop fromt eh endocrine target
short loop from anttieor pituaty hypothalamus

34
Q

primary disoerds

A

from cell that secrete hormone

35
Q

secondar disorder

A

where there is too little or too much tropic hormone from pituatry

36
Q

3rd order

A

due to hypothalmic defects

37
Q

hyperresponsiveness cause

A

alternation in recptoer for hormone, disorderd post recpeotr failure, failure of metaboi activation of hormone

38
Q

hyperresponsivness

A

thyrodi hormone adrenaline mediated liposisly

39
Q

what happens after prologed exposure to low hormone levels

A

up regulation of receptor number

40
Q

what happens with prolonged high exposrue to hormone

A

down regulatio f receuprot number due to decreasecd senstity of tissue to hormone

41
Q

what is permissive effect of hormoens

A

when one hormone enhances the effect of another hormone when used in combination , ie when epineer only cause slight lipois but when used wit thryoid hores it is much greater

42
Q

why does th cause increaed lymp;o for epinerh

A

due to it being periem to it
th does not cause fatty acid release

43
Q

antagonsit effect

A

where one drug stops another drug from working as well
