	Add the basilar artery. It is formed by the union of the vertebral arteries at the pontomedullary junction and ascends superiorly along the ventral surface of the pons within the basilar sulcus.
	Add the anterior view.
	Add the posterior communicating arteries, which connect the internal carotid arteries to the posterior cerebral arteries.

	Add the posterior cerebral arteries. They course posteriorly around the midbrain and supply the occipital lobe and inferior temporal lobe.
	Add the middle cerebral arteries. They course laterally within the lateral sulcus and supply the lateral surface of the frontal, parietal, and temporal lobes.
	Add the anterior cerebral arteries. They course anteromedially within the longitudinal fissure and supply the medial surfaces of the frontal and parietal lobes.

Since the arterial vessels of the brain are so small, only the larger vessels can be seen on our cadaver.

Using the diagram, trace the blood flow to each of the lobes supplied by the major arteries listed above.

ACA → medial frontal and parietal cortex

MCA → lateral cerebral convexity

PCA → occipital cortex and inferior temporal surface

Using the diagram, predict the consequences of injury to the following cerebral arteries:

Middle

Posterior
