The posterior cerebral artery primarily supplies blood to which part of the brain?

• A. Lateral surface of the brain
• B. Frontal lobe
• C. Visual cortex
• D. Temporal lobe

Answer: (C)

The posterior cerebral artery (PCA) is primarily responsible for supplying blood to the occipital lobe and the inferior parts of the temporal lobe, which includes the visual cortex. The visual cortex is critical for processing visual information, which makes this area particularly significant in terms of blood supply from the PCA. Understanding the vascular territories of the brain is essential for recognizing how different regions are affected in cases of stroke or other vascular conditions. In this context, the PCA's role in supplying the visual cortex underscores its importance in visual processing and perception.
