<prompt> Which structure connects the Brocas area and Wernicke area?Arcuate fasciculusAnterior commissureCorpus callosumFornix  <response>: - Arcuate fasciculus connects Wernickes area present in posterior superior temporal gyrus of dominant hemisphere sensory area of speech to Brocas speech area present in prefrontal premotor facial region of cerebral coex to integrate language understanding skilled motor function. Damage to Wernickes area wernickes aphasia lack meaning Damage of Brocas area motor aphasia vocal system couldnt emit words Damage of Arcuate fasciculus conduction aphasia - Anterior commissure white mattes tracts that connects two temporal lobes of cerebral hemispheres across midline especially amygdala - Corpus callosum: band of nerve fibers providing bidirectional neural connections bw most of coical areas of two cerebral hemispheres except anterior poions of temporal lobes - Fornix - c - shaped bundle of nerve fibers in brain acting as major output tract for hippocampus
