Visual area of cortex is supplied by –
**Core Concept**
The visual area of the cortex, responsible for processing visual information, is primarily supplied by the **posterior cerebral artery**. This artery is a terminal branch of the **basilar artery**, which arises from the **vertebral arteries**. The posterior cerebral artery plays a crucial role in supplying blood to the **occipital lobe**.
**Why the Correct Answer is Right**
The correct answer is related to the **posterior cerebral artery**, as it is the primary artery responsible for supplying the **visual cortex**. The visual cortex, located in the **occipital lobe**, receives its blood supply from the **posterior cerebral artery**, which ensures proper functioning of visual processing.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it is not the primary supplier of the visual cortex.
**Option B:** Incorrect as it is not directly related to the visual area of the cortex.
**Option C:** Incorrect because, although it supplies parts of the brain, it is not primarily responsible for the visual area.
**Clinical Pearl / High-Yield Fact**
The **posterior cerebral artery** is crucial for visual function, and occlusions can lead to **homonymous hemianopia**.
**Correct Answer:** D. Posterior cerebral artery.
