The median aperture of the brain (apertura medialis ventriculi quarte ) or foramen of Magendie is an opening in the hollow nerve tube, connecting the fourth ventricle of the brain with the subarachnoid space .
The median aperture, along with the paired lateral apertures (foramina of Luschka ) are the primary routes for cerebrospinal fluid to escape into the cisterna magna . The Foramen of Magendie is named for François Magendie , who first described it.
