PostSubject: more bio!!! ;D Tue Feb 24, 2009 1:47 pm

now coming to human anatomy!!

1. nervous sys:

a) the structure that protects eyeball and maintains its shape....is it vitreus humour or sclera?
b) dilation of blood vessels and slowing of heart beat is done by para-sympathetic or sympathetic n.sys?
c) what is the function of otoliths in human ear?

2. reproductive sys:

a) is oestrogen secreted by ovary or corpus leuteum or placenta? actually, it has been given under all three headings!!! in a q.bank, they have given ovary as the ans!!! Suspect

b) corpus leuteum secretes what?

c) the hormone which stimulates contraction of uterus during child birth- it is progesterone???? there are diff answers in diff books..


3. health:

ther was a q: name the combined vaccine given to babies to build immunity against 3 diseases.

so, all of us wrote DPT...my genius teacher told its wrong..she said its MMR-mumps measles n rubella Suspect

tell me which is right!!!


i am completely dependent on god for this bio!!

1a vitreous humour
b parasympathetic n.system
c do we have it in the portion? cause i haven't read it in concise

2a mention all cause it can't be wrong if it was mentioned under all 3 subheadings
b progesterone and oestrogen
c oxytocin from the posterior pituitary

3a i would've also written DPT, cause there's a table in concise giving a list of vaccines to be taken at appropriate timings.

haha, dont worry anu, you'll do well!=)
