++

Which of the following best completes the following analogy: Anterior circulation is to posterior circulation, as

++
++
++

A. anterior cerebral hemispheres, basal ganglia, thalamus, ventral brain stem, and ventral spinal cord are to the posterior cerebral hemispheres, cerebellum, dorsal brain stem, and dorsal spinal cord

++
++

B. internal carotid artery is to the vertebral and basilar arteries

++
++

C. vertebral and basilar arteries are to the internal carotid artery

++
++

D. anterior inferior cerebellar artery is to the posterior inferior cerebral artery

++
++
++

Which of the following statements best describes the normal path blood takes from one vertebral artery to the left occipital lobe?

++
++
++

A. Basilar artery, left posterior cerebral artery

++
++

B. Basilar artery, left posterior communicating artery, left middle cerebral artery

++
++

C. Basilar artery, left superior cerebellar artery, left posterior cerebral artery

++
++

D. Left posterior inferior cerebellar artery, left posterior cerebral artery

++
++
++

Which of the following arteries is NOT a branch of the internal carotid artery?

++
++
++

A. Posterior inferior cerebellar artery

++
++

B. Ophthalmic artery

++
++

C. Anterior choroidal artery

++
++

D. Posterior communicating artery

++
++
++

Which of the following best completes the analogy about cerebral arterial distributions: The middle cerebral artery is to the anterior cerebral artery, as

++
++
++

A. the basal ganglia is to the thalamus

++
++

B. the inferior frontal lobule is to the occipital pole

++
++

C. the cingulate gyrus is to the superior temporal gyrus

++
++

D. the lateral postcentral gyrus is to the medial postcentral gyrus

++
++
++

Which description of the brain stem arterial distributions is most accurate?

++
++
++

A. Arterial branches supply pie-shaped wedges of tissue, beginning at dorsal midline and extending circumferentially.

++
++

B. Short circumferential branches supply the dorsal brain stem; long circumferential branches supply the ventral brain stem.

++
++

C. Arteries course on the ventral surface and send branches dorsally.

++
++

D. The basilar artery supplies the midline; the vertebral arteries, the next lateral territory; and the cerebellar arteries supplying most ...
