cerebral circulation

which artery is a part of anterior circulation and a branch of common carotid from the aorta

internal carotid artery

which arteries merge to becomes the basilar artery

vertebral arteries

which artery in the posterior circulation ascends in the transverse foramen of cervical vertebrae

vertebral arteries

what part of the brain recieves arterial supply from anterior circulation

frontal lobe, parietal lobe, internal capsule, anterior part of corona radiata, diencephalon

what part of the brain recieves arterial supply from posterior circulation

spinal cord, brain stem, cerebellum, occipital lobe, temporal lobe, diencephalon

track the anterior circulation pathway

internal carotid divides into anterior cerebral, middle cerebral, posterior communicating then branches before the terminus into opthalamic and anterior choroidal

track posterior circulation pathway

vertebral arteries merge to become basilar artery, branches into anterior spinal artery and PICA then terminates by dividing into posterior cerebral arteries which branch into SCA, pontine perforating arteries, and AICA

what does the circle of willis consist of

anterior comunicating, anterior cerebral, internal carotid, posterior communicating, posterior cerebral

T/F the circle of willis includes the midde cerebral artery

F (false)

what are the three cerebral arteries

ACA, MCA, PCA

what do cortical branches of the cerebral arteries supply

cerebral cortex

subcortical/deep penetrating branches of cerebral arteries supply what

subcortical white and basal ganglia and thalamus

what is the internal capsule made up of

posterior limb, anterior limb, genu

what is the arterial supply of the midbrain

PCA, SCA, BA

what is the arterial supply of the medial pons

BA

what is the arterial supply of the lateral pons

AICA

what is the arterial supply of the medial medulla

VA, ASA

what is the arterial supply of the lateral medulla

VA, PICA

the spinal cord recieves blood supply from

ASA, PSA

what supports the anterior spinal artery

radicular/segmental arteries from the aorta w

what supports the posterior spinal artery

radicular/segmental arteries

what types of arteries penetrate the spinal cord

intrinsic arteries

track venous drainage

inferior sagittal sinus and cavernous sinus to superior sagittal sinus, straight sinus, and transverse sinus to confluence of sinuses and sigmoid sinus to jugular vein
