Which artery feeds the medial wall of the occipital lobe and the inferior part of the temporal lobe?

• A. Anterior Cerebral Artery
• B. Posterior Cerebral Artery
• C. Middle Cerebral Artery
• D. Angiography

Answer: (B)

Understanding arterial territories helps explain this pattern. The posterior cerebral artery supplies the medial wall of the occipital lobe, where the primary visual cortex sits along the calcarine sulcus, and it also extends into the inferior temporal lobe, which is part of the ventral stream involved in recognizing objects. In contrast, the anterior cerebral artery mainly feeds the medial aspects of the frontal and parietal lobes, and the middle cerebral artery covers the lateral surfaces, including much of the lateral temporal lobe. Angiography is an imaging technique, not a vessel. So the artery that fits both the medial occipital wall and the inferior temporal lobe is the posterior cerebral artery.
