Exam 1 Brain Arterial Supply Flashcards
Pass behind the ear into the temporal lobe & enter the subarachnoid space
Internal carotid artery
Carry blood INTO cranial vault
Internal Carotid Artery
Runs posteriorly to the medial end of the fissure of Sylvus
Internal carotid artery
Bifurcates into 2 main branches: anterior & middle cerebral artery
Internal carotid artery
Goes above the optic chiasm to the medial surface of the cerebral hemispheres.
Anterior Cerebral artery
Aches around the genu (horn) of the corpus callosum
Anterior cerebral artery
Supplies blood to the medial cortex
Anterior cerebral artery
Travels along the longitudinal fissure
Anterior cerebral artery
Most commonly involved in strokes
middle cerebral artery
Brings blood to the entire lateral aspect of each hemisphere
Middle cerebral artery
provides most of the blood supply to the corpus striatum
Middle cerebral artery
Internal carotid artery also includes the _______ ______ artery & ______ ________ artery
Anterior communicating artery & posterior communicating artery
Joins the anterior cerebral arteries of each hemisphere together
Anterior Communicating artery
Joins the middle cerebral arteries to the posterior cerebral arteries, which are part of the basilar artery system
Posterior communicating artery
Both ascend the spinal column & enter the brain through the magnum foramen.
Vertebral artery
Once inside the brain, they continue to ascend traveling beside the brain stem. At the lower border of the pons the two______ ______ join together to form the basilar artery
Vertebral artery
Supplies the cerebellum & takes blood to the lateral medulla
Posterior inferior cerebellar
The sides of the Pons & the cerebellum receive blood from the ______ ______ _____ artery & the ________ ______ artery. Both branch off of the basilar artery
Anterior inferior cerebellar & Superior cerebellar artery
Anterior inferior cerebellar artery also has a branch, artery that supplies the inner ear
Labyrinthine/ internal auditoritory
At the superior border of the pons, the basilar artery divides to form the 2 ________ _______ arteries
Posterior cerebral arteries
Before the basilar artery divides, several other arteries arise from it. Name these:
Anterior, Inferior, and posterior cerebellar arteries as well as the pontine
branches.
The cerebellum & the pons are supplied by branches of the:
Basilar artery
Posterior cerebral arteries supply the medial area of the ______ ____ & the inferior aspects of the _____ ___
Occipital lobes; Temporal lobes
Also supply the midbrain & deliver blood to the thalamus
Posterior cerebral arteries
