help with physiology

[ch5112]

Hi..I'm trying to go through previous exam questions but can't really find the right answers for questions.

 

Pls help!

 

 

 

1. The brain is located within the skull, and further protected by the meningies and CSF. Which of the following statements about these features of anatomical organisation is correct?

 

 

a) There is a direct passage(aqueduct) connecting the lateral ventricles to the fourth ventricle-----wrong

 

b) As well carrying oxygenated blood to the brain, the cerebral arteries also resorb CSF from the sub-arachnoid space---wrong?

 

c) the only brain regions that are separated by dura mater are 1: between the dorsal aspect for the two cerebral hemisphere, and 2: between cerebellum and cerebrum

 

d)although the fluid filled ventricles were obvious until the application of microscopes to the study of brain structure

 

e)the skull provides mechanical protection for the brain and also prevents the intracranial presusre from rising if there is an increase in intra-cranial volume.

 

 

 

My answer for this question is e)...is this right??

Some of the phrasings on the questions are odd. Are you sure you are writing them, or if they are not in English translating, correctly?

 

Think about what a skull is supposed to do. It keeps the brain safe by being a solid barrier, solid barriers don't release pressure very well. You should be able to whittle the answers down to a couple by thinking about what the use of the thing in question is used for or its structure.
