Which cerebral artery supplies the frontal, parietal, occipital, and temporal lobes?

The middle cerebral artery is the primary vessel that supplies blood to many critical areas of the brain, notably including the frontal, parietal, occipital, and temporal lobes. This artery is responsible for providing oxygenated blood to the lateral surfaces of the cerebral hemispheres. Its extensive distribution allows it to supply portions of the primary motor and sensory cortices, which are crucial for voluntary movement and sensory perception.

The regions supplied by the middle cerebral artery include critical areas involved in language, motor control, and sensory processing. Its role in providing blood flow to the insula and the superior temporal gyrus further emphasizes its significance in various neural functions, including speech comprehension and the integration of sensory information.

In contrast, other arteries serve more specific roles. For example, the anterior cerebral artery primarily supplies the medial portions of the frontal and parietal lobes, while the posterior cerebral artery focuses on the occipital lobe and parts of the temporal lobe situated on the medial aspect. The basilar artery doesn't directly supply any of these lobes but rather gives rise to branches that support the brainstem and cerebellum. Thus, the choice of the middle cerebral artery is based on its extensive coverage of the lateral aspects of the major cerebral lob
