Flashcard 17: What artery supplies the medial and lateral midbrain? _____
Answer: Posterior cerebral artery
Flashcard 18: Which vessel of the Circle of Willis arises from the terminal bifurcation of the basilar artery?
Answer: Posterior cerebral artery
Extra: The posterior cerebral artery (PCA) arises from the terminal bifurcation of the basilar artery. It supplies the occipital lobe and the inferior portion of the temporal lobe. It is connected to the internal carotid artery via the posterior communicating artery, completing the posterior part of the Circle of Willis.
Flashcard 19: Which major cerebral artery supplies the lateral surface of the frontal, parietal, and temporal lobes?
Answer: Middle cerebral artery (MCA)
Extra: The MCA is the largest branch of the internal carotid artery and supplies the lateral surface of the frontal, parietal, and temporal lobes. This territory includes the motor and sensory areas for the face and upper limbs, as well as Broca's and Wernicke's areas in the dominant hemisphere.
Flashcard 20: Which cerebral artery supplies the anterior limb of the internal capsule? _____
Answer: Anterior cerebral artery
