Question: The blood supply to inferior and mesial portion of temporal lobe is by which of the following

Options:

• Middle cerebral artery
• Posterior cerebral artery
• Arcuate artery
• Posterior communicating artery

Correct Answer: Posterior cerebral artery

Explaination: The temporal lobe receives blood from both the carotid and the vertebrobasilar systems<br>Structures in the temporal lobe supplied by the anterior choroidal artery are the anterior end of the parahippocampal gyrus, the uncus, the amygdala, and the choroid plexus in the temporal horn of the lateral ventricle<br>The middle cerebral artery, supplies the cortex of the superior and middle temporal gyri and the temporal pole<br>The temporal branches of the posterior cerebral artery supply the inferior surface of most of the temporal lobe, but not the temporal pole, thus causing behavioral or memory disturbances in PCA stroke
