Detailed explanation-1: -The median aperture (foramen of Magendie) opens on midline into a subarachnoid space inferior to the cerebellum called the cisterna magna and into the quadrigeminal cistern in the region of the tectum of the midbrain.
Detailed explanation-2: -Cerebrospinal fluid produced in the fourth ventricle drains into the cisterna magna via the lateral apertures and median aperture. It receives CSF from the fourth ventricle via the median foramen of Magendie and the paired lateral foramen of Luschka.
Detailed explanation-3: -The cisterna magna (or cerebellomedullar cistern) is one of three principal openings in the subarachnoid space between the arachnoid and pia mater layers of the meninges surrounding the brain. The openings are collectively referred to as the subarachnoid cisterns.
