what connects the 4th ventricle and subarachnoid space laterally
foramina of Luschka
how does the CSF go from lateral ventricles to the 3rd ventricle
through the interventricular foramina
what are the 2 foramen that link the 4th ventricle to subarachnoid space
foramina o fmagendie and luschka
where is the subarachnoid space located
between arachnoid and pia
how does CSF fluid return to venous blood
