Document Summary

Which two are most superior: lateral, beneath the lateral third forth. Which ventricle sits immediately below the lateral ventricles: third, very midline structure in the brain. Temporal horn comes near the temporal lobe. Majority of the ventricle, not the horns body. What is the septum pellucidum: membrane separating lateral ventricles, see a little bit in the front, most curve portion of it, c-shaped. Which foramen connects the lateral ventricles to the third ventricle: formation of monro, aka interventricular foramen, from third to forth: aqueduct of sylvis, aka cerebral aqueduct. Foramen in the forth ventricle: foramen of magendie, aka median apertures, on the posterior wall of the forth ventricle, foramen of luschka: two lateral foramen of apretures in forth ventricle. Inferior to the cerebral aqueduct: posterior to the pons. Inferior to the pons: anterior to the cerebellum. Thalamus creates the lateral wall of third ventricle, Third ventricle is very thin, immediate medial to the thalamus, (two linked together)
