CEREBRAL IRRIGATION

CEREBRAL IRRIGATION

1. They are known as cerebral arteries (arteriae cerebri) arteries distributed in the cortex cerebral, are three main pairs of arteries and their branches that supply the brain.

2. Middle Cerebral Artery

   • Is one of the arteries supplying the brain.
     • Media Cerebral
       • Cortical branches
         • The posterior temporal artery
         • The anterior temporal artery
         • The middle temporal artery
     • Posterior Cerebral and Anterior Cerebral
       • originating from the terminal portion of the middle cerebral and exhibit two branches: anterior and posterior.
         • Artery of central sulcus.
         • Artery of postcentral sulcus
         • Precentral sulcus artery
     • Branches striated proximal side of the anterolateral central artery
     • Branches striated distal side of the anterolateral central artery
     • Artery of the temporal pole
     • Sphenoid portion of the middle cerebral artery; horizontal portion of the middle cerebral artery; M1 segment of the middle cerebral artery
     • Anterior temporal artery
     • Artery of uncus
     • Insular portion of the middle cerebral artery; M2 segment of the middle cerebral artery

3. Posterior Cerebral Artery

   • Is each of two arteries (right and left) that originate at the bifurcation of the basilar artery.
     • Occipital artery average
     • Middle Occipital artery
     • Postcomunicante portion of the posterior cerebral artery; P2 segment of the posterior cerebral artery
     • collicular Artery
     • Short circumferenciales Arteries
     • talamogeniculada artery
     • Posteromedial central arteries
     • Thalamo-perforating artery
     • Medial posterior choroidal branches of the posterior cerebral artery
     • Lateral occipital artery; P3 segment of the posterior cerebral artery
     • Peduncular branches of the posterior cerebral artery
     • Posterior lateral choroidal branches of the posterior cerebral artery

4. Anterior Cerebral Artery

   • Originates from the internal carotid artery.
     • A1
       • This segment originates from the internal carotid artery extends to the anterior communicating artery of the brain.
     • A2
       • This segment extends from the anterior communicating to the bifurcation forming callosomarginal pericallosa and arteries.
         • The medial orbitofrontal artery (or medial frontobasal)
         • Artery frontal pole
     • A3
       • Also called pericallosal artery, this is one (or only) terminal branch of the ACA, extending posteriorly in the groove pericalloso
         • Artery callosomarginal
     • A4 Y A5
       • Smaller branches of "callous" arteries of the ACA (supracallosas)
     • Precommunicating portion of the anterior cerebral artery; A1 segment of the anterior cerebral artery
     • Artery frontal pole
