PHYS20009 Past exams

[MelonBar]

Chickenchowmein and I are going to compare answers to 2012 s1 and s2 soon, anyone want to join in?

It would also be amazing if someone had answers to the older past exams eg 2011, 2009.

To make it clear this Research-Based Physiology, not Human phys.

Melon would you like me to send you all of my answers for all of the research based phys practise exams I did last year?
If so, PM me your email

Hey turtle, do you mind sending the answers to me as well?
I'll PM you in case


Thanks so much!!

yeah turtle that would be so good (pm'd)

[MelonBar]

All of the following statements with respect to the Cardiovascular responses in a human practical class are correct except for:

A. On an ECG, the time between the commencement of ventricular excitation and the end of ventricular repolarization is measured from Q to the end of T.
B. The time taken for action potential spread over the entire ventricular myocardium can be approximated from R to S.

Which do you think is correct/incorrect?

Also plz turtle exam is like 16 hours from now : (

[lach2434]

I said B was incorrect because I thought that Q->S exciting the bundles of His counted as ventricular myocardium excitation

[MelonBar]

Yeah, I'm leaning towards B now but I'm not sure if the bundles of His are part of the ventricular myocardium.

What did you think of this one?

Which of the following would be most appropriate for testing on isolated tissues as opposed to whole organisms or cells?

A. The effects of varying light patterns on teh developing optic nerve in newborns
B. The effects of anabolics steroids on skeletal muscel development
C. The effects of anaesthetic on action potential conduction in peripheral nerves.
D. The effects of a novel compound on reducing the likelihood of contracting skin cancer.
E. The effect of varying diet on circulating hormone levels.

For me it's between C or D but conflicting answers between diff people.

Also: this one:

20. Identifty which of the foll. steps would NOT be included in a study where you are testing specific hypotheses.

A. State the hypotheses
B. Set the signifiance (p value) levle before the research study
C. Eliminate all data outliers
D. Obtain the p value using a computer program such as excel or SPSS
E. compare the p value to the signifiance level and make the statistical decision

[lach2434]

For the first one I would say C. I just feel like the  contraction of skin cancer is something you would have to test in a whole organism where if we isolated a nerve we could still measure its ability to conduct an AP?
For the second one I went for C. I dont think we eliminate outliers we just dont include them in statistical analysis? i think you are always meant to justify omitting outliers and not just do it.

[MelonBar]

Actually I agree with all your answers : )

thanks dude.

[MelonBar]

How are you answering the thermoreg question (S2, 2012). The results are wack. I can say stuff like peripheral vasoconstriction evidenced by lower skin temps but there's some odd results in there. I don't think we should be discussing what 'should' have occurred like in the assignment because there's no specific instruction for it in the prompt.

I think deanne made some strong hints that the thermoreg quesiton will defo be on the exam tomorrow, so I think its worth a discussion

[lach2434]

yeah that question is ridiculous. what i thought was that we could justify vasoconstriction because of the decreased peripheral temperatures and increased diastolic blood pressure (potentially due to venous return increase)... but then youd have to try and explain why MAP still went down which could have been because of a decrease in cardiac output...but HR didnt change....
and i have no idea whats going on with the metabolic rate increasing and then decreasing...
i hope the results we get on our exam make a bit more sense....

12 is B- NA binds to B1 in heart while binding to alpha receptors on blood vessels.
