Lateral apertures (of Luschka)

Last revised by Dr Daniel J Bell on 09 May 2022

The lateral apertures (of Luschka) (also known as the foramina of Luschka) are two of the foramina in the ventricular system and link the fourth ventricle to the cerebellopontine cistern. Together with the median aperture (of Magendie) they comprise two of the three sites that CSF can leave the fourth ventricle and enter the subarachnoid space.

They are located at the lateral-most aspect of the fourth ventricle and drain into the subarachnoid space at the cerebellopontine angle cistern immediately posterior to the root of the glossopharyngeal (IX) nerve.

History and etymology

Hubert von Luschka (1820-1875) was a German anatomist active in the second half of the nineteenth century who was one of the first anatomists to research normal, as well as diseased, cadavers. He has lent his eponym to quite an impressive range of structures, at least 23 by one count 3!
