Where is posterior cerebral artery located?
occipital lobe
The posterior cerebral artery curls around the cerebral peduncle and passes above the tentorium to supply the posteromedial surface of the temporal lobe and the occipital lobe. The visual cortex responsible for the contralateral field of vision lies in its territory.
What is P2 artery?
P2: The P2 segment begins at the posterior communicating artery and curves around the ambient cistern of the midbrain, and courses above the tentorium cerebelli. This segment commonly gives off anterior and posterior inferior temporal arteries.
Is posterior communicating artery same as posterior cerebral artery?
Posteriorly, it communicates with the posterior cerebral artery. The brain is supplied with blood by the internal carotid arteries and also by the posterior cerebral arteries; the posterior communicating arteries connects the two systems….

What does the PCA feed?
| Stroke Model | The Posterior Cerebral Artery (PCA) supplies the occipital lobe, the inferior part of the temporal lobe, and various deep structures including the thalamus and the posterior limb of the internal capsule. Primary and secondary visual areas. Functions in the sensation and interpretation of visual input.
What is posterior cerebral artery stroke?
Posterior Cerebral Artery Strokes PCA strokes will primarily cause a visual field loss or homonymous hemianopia to the opposite side. This large occipital or PCA stroke causes people to be “blind” on one side of the visual field. This is the most common symptom of a large occipital lesion or PCA stroke.
Which cerebral artery gives the posterior communicating artery?
internal carotid artery
The posterior communicating artery originates from the posterior aspect of the C7 (communicating) segment of the internal carotid artery and extends posteriormedially to anastomose with the ipsilateral posterior cerebral artery and form part of the circle of Willis.
What causes a PCA stroke?
The most common causes of PCA strokes include atherosclerosis, small artery disease and embolism 5.
