Question 1
pts
Uncal herniation occurs when
a cerebellar tonsil shifts through the foramen magnum.
the cingulate gyrus shifts under the falx cerebri.
the diencephalon shifts from the middle fossa straight downward through the tentorial notch into the
posterior fossa.
Correct!
the hippocampal gyrus shifts from the middle fossa through the tentorial notch into the posterior fossa.
Uncal herniation (hippocampal herniation, lateral mass herniation) occurs when the
uncus or hippocampal gyrus (or both) shifts from the middle fossa through the
tentorial notch into the posterior fossa, compressing the ipsilateral third cranial nerve
impairing parasympathetic functioncarried in the periphery of the nerve, then the
contralateral third cranial nerve, and finally the mesencephalon, inducing coma.
Question 2
pts
What are the areas of the brain that mediate several cognitive functions, including vigilance, reasoning,
and executive functions?
Parietal
Occipital
Limbic
Correct!
Prefrontal
It is the prefrontal lobe that mediates several cognitive functions, including vigilance,
reasoning, and executive functions.
Question 3
pts
The body compensates to a rise in intracranial pressure by first displacing
Correct!
cerebrospinal fluid (CSF).
arterial blood.
