Right and Left Vertebral Arteries

Right and Left Vertebral Arteries

1. Basilar Artery

   • Posterior Cerebral Artery
     • Posterior Communicating Artery
       • Middle cerebral artery
         • Anterior cerebral artery
           • Internal Carotid Artery
             • Circle of Willis
               • "The function of the 'circle of willis' allows the blood to flow in different directions, it is the round-about for the brain." Hameed, S. [Neuroscientifically Challenged]. (2018, April 5). 2-Minute Neuroscience: Blood Supply of the Brain. 
               • Circle of Willis (Hameed, 2018).
                 • (Hameed, 2018, 2-Minute Neuroscience)
             • BASILAR ARTERY
               • INFO
                 • "The internal carotid artery and the vertebral artery together make up the basilar artery." (Halladay & Chung, 2019)
               • Superior cerebellar artery
                 • INFO
                   • "The superior cerebellar artery originates from the basilar artery and supplies the superior surface of the cerebellum and parts of the midbrain." (Anatomynext, superior cerebellar artery, n.d.)
             • INFO
               • "Part of the common carotid artery, it supplies the anterior two-thirds of the brain hemispheres." (Papathanasiou & Coppens, 2017, p.39; Purves & Williams, 2001))
             • Where it all starts!!
               • (Jahn, 2014, Pathway of the blood flow of the brain)
           • anterior communicating artery
             • INFO
               • "The anterior communicating artery connects the left and right anterior cerebral arteries across the longitudinal fissure." (2018, November 26. Anterior communicating artery)
           • INFO
             • "The anterior cerebral artery supplies the anterior part of the frontal lobe and parietal lobes, including the sensorimotor cortex part corresponding to the lower limb the medial surface of the hemisphere." (Papathanasiou & Coppens, 2017, p.39)
         • INFO
           • "The middle cerebral artery is the final branch of the internal carotid supplying about two-thirds of the cerebral hemisphere, from the corical surface to its depths.  It specifically supplies the basal ganglia, the posterior lateral part of the frontal lobe, and the lateral aspects of the temporal and parietal lobes." (Papathanasiou & Coppens, 2017, p.39-40)
         • External Carotid Artery
       • INFO
         • "The posterior communicating arteries connect the two systems and provides redundancies or collaterals in the cerebral circulation. If one system is blocked or narrowed, the other system can take over." (Posterior communicating arteries, 2018).
     • INFO
       • "The posterior arteries supply the posterior part of temporal lobe and the occipital lobes of the left cerebral hemisphere and the right hemisphere as well as some subcortical structures." (The Internet Stroke Center, 2019)

2. INFO

   • "The confluence of the two vertebral arteries forms the basilar artery". "The vertebrobasilar arteries supply the posterior two-fifths of the cerebrum, part of the cerebellum, and the brain stem." (Papathanasiou & Coppens, 2017, p.40; The internet stroke center, n.d.)
