What structures does the Posterior CEREBRAL Artery supply (the terminal end of the basilar)? | Superior Colliculus (visual refleses) Medial Geniculate (hearing) Lateral Geniculate (vision) CN III Occulomotor cell bodies |
What structures does the superior CEREBELLAR artery supply? | Inferior colliculus (auditory pathway) Trochlear CN cell bodies |
What structures does the anterior inferior CEREBELLAR | CN VI abducens cell bodies Facial motor nuclues |
What structures does anterior spinal artery supply? | Pyramids -corticospinal tract medial lemniscus CN XII Hypoglossal cell bodies (tongue muscles) |
What structures does the posterior inferior CEREBELLAR artery supply? | inferior cerebellar peduncle spinothalamic tract (pain, temp, pressure) |
What structures does the posterior spinal artery supply? | gracillus cuneatus |
What structures does the anterior choroidal artery supply? | Hippocampus (memory) Globus pallidus (motor) |
Why is the anterior choroidal artery important? | because it is prone to occlusion and the structures it supplies (hippocampus and globus pallidus) are especially vulnerable to loss of blood supply |
What structures does the opthalamic artery supply? | the eye and the surrounding area |
Why is the opthalamic artery important? | because the central artery of the retina is a branch off the opthalamic a |
