Flashcard 44: Which cerebral artery supplies the language centers (Broca's area, Wernicke's area)? _____

Answer: Middle cerebral artery

Flashcard 45: The _____ branches of the posterior cerebral artery supply the splenium, parahippocampal gyrus, and fusiform gyrus

Answer: cortical

Extra: The **cortical branches** of the PCA supply the splenium of the corpus callosum and the medial and inferior surfaces of the temporal and occipital lobes (including the parahippocampal and fusiform gyri). The **central (deep) branches** (e.g., thalamogeniculate, thalamoperforating) supply the thalamus and midbrain.
