MEDICAL NEUROSCIENCE QUIZ 2
COMPLETE ANSWERS
Which of the following functional regions of the cerebral cortex is supplied by the
anterior cerebral artery? - Answer-WRONG Representation of the contralateral hand
in somatic sensorimotor cortex
A older patient with a history of hypertension and cigarette smoking has recently
been injured in a car crash on Franklin Street (a famous street in Chapel Hill, North
Carolina, USA where cars park on the right-hand side of the street) while attempting
to pull out of a parallel parking space. This task requires looking back to the left. The
patient says that he just "never saw the car coming" in the lane of traffic. Although
the patient is being evaluated for treatment of his orthopedic injuries, you should also
wonder if there may have been a prior stroke that contributed to this patient's
accident. Which cerebral artery should you consider when exploring whether a prior
stroke contributed to this accident? - Answer-Right posterior cerebral artery
Which of the following sequences (indicated by >) correctly captures the drainage of
venous blood from the dorsal aspects of the cerebral hemispheres? - Answer-
superior sagittal sinus > transverse sinus > sigmoid sinus > internal jugular vein
Which of the following gyral structures is supplied by the middle cerebral artery?
(Select all that apply.) - Answer-WRONG inferior temporal gyrus; inferior frontal
gyrus
Two important functional regions of the cerebral cortex are located on the lateral
aspects of the hemispheres and are critical for language function. Based on the
overview of these regions encountered so far, which of the following statements
concerning these regions is most accurate? - Answer-Damage to Broca's area in the
left hemisphere would likely produce great difficulty with speech production
Which of the following arteries typically contributes to the posterior circulation of the
brain? (Select all that apply.) - Answer-Posterior cerebral artery; Vertebral Arteries;
Basilar Arteries
Which of the following arteries contribute to the anterior circulation of the brain?
(Select all that apply.) - Answer-WRONG Anterior Cerebral artery; middle cerebral
artery; internal carotid artery
A patient presents with weakness and numbness in her left arm and the lower left
side of her face, with all other functions being normal. As a budding clinician or
functional neuroanatomist, you would suspect a possible stroke involving a branch of
which artery? - Answer-WRONG Right anterior cerebral artery
A patient presents with "foot drop", meaning that when the person walks, one foot is
"floppy" requiring exaggerated movements to compensate for weak ankle
dorsiflexion during ambulation. Of the possible stroke syndromes attributable to
