Lesson 11: Cerebrum Flashcards
What connects Wernicke to Broca?
Arcuate fibres
What connects the frontal lobe to the temporal lobe?
Uncinate fasciculus
What connects the frontal lobe with the occipital and temporal?
Longitudinal fasciculus
What supplies the internal capsule? What happens with a stroke to these branches?
The middle cerebral artery’s striate branches.
