Cerebral Arteries and Stroke Effects

Flashcards covering the anatomical origins, blood supply regions, and clinical stroke symptoms associated with the major cerebral arteries based on the lecture transcript.

Anterior cerebral artery (ACA)

An artery that extends upward and forward from the internal carotid artery and supplies blood to the frontal and parietal lobes, basal ganglia, and corpus callosum.

ACA stroke

A condition that can cause opposite leg weakness.

Middle cerebral artery (MCA)

The largest branch of the internal carotid artery that supplies blood to Broca's and Wernicke's areas, the temporal lobe, and the primary motor cortex.

MCA stroke

The most common location of stroke, which can cause aphasia.

Posterior cerebral artery (PCA)

An artery that stems from the basilar artery and supplies blood to the occipital lobes, cerebellum, and inferior temporal lobes.

PCA stroke

A condition usually secondary to embolism from lower segments of vertebral heart.

Basilar artery

The artery from which the posterior cerebral artery (PCA) stems.

Internal carotid artery

The artery that the anterior cerebral artery (ACA) extends from and whose largest branch is the middle cerebral artery (MCA).

Broca's and Wernicke's areas

The specific language-related areas of the brain supplied by the middle cerebral artery (MCA).
