CMD 377 Lecture Notes - Lecture 11: Posterior Cerebral Artery, Anterior Communicating Artery, Subclavian Artery
Document Summary
Blood supply to the brain and spinal cord. Arises from the aortic arch, which divides into: common carotid arteries. Internal carotid arteries (located on each side of skull) Two major vessels: internal carotid arteries. Supplies most of the telencephalon and much of the diencephalon: vertebral arteries. Parts of the diencephalon, spinal cord, and occipital and temporal lobes. Branches of the internal carotids: internal carotid arteries enter the brain through the petrous portion of the temporal bone enter subarachnoid space, further divide into. Middle cerebral arteries (mca: the internal carotids supply most of the cerebrum. Vertebral-basilar system: vertebral arteries arise from the subclavian arteries, at the junction between medulla and pons, fuse and form the basilar artery, at the level of the midbrain, bifurcates into two posterior cerebral arteries (pca) Branches of vertebral arteries: posterior inferior cerebellar arteries (pica) Also supply laterla medulla: anterior inferior cerebellar arteries (aica) Arise from the basilar artery just rostral to the origin.
