It may refer to: * Aditus to mastoid antrum, in the ear * Laryngeal aditus, the opening that connects the pharynx and the larynx * Omental foramen In human anatomy, the omental foramen (epiploic foramen, foramen of Winslow after the anatomist Jacob B.

Aditus To Mastoid Antrum
The aditus to mastoid antrum (otomastoid foramen or entrance or aperture to the mastoid antrum) is a large irregular cavity that leads backward from the epitympanic recess into a considerable air space named the tympanic or mastoid antrum. The antrum communicates behind and below with the mastoid air cells, which vary considerably in number, size, and form; the antrum and mastoid air cells are lined by mucous membrane, continuous with that lining the tympanic cavity. On the medial wall of the entrance to the antrum is a rounded eminence, situated above and behind the prominence of the facial canal; it corresponds with the position of the ampullated ends of the superior and lateral semicircular canals. See also * Aditus * Mastoid antrum The mastoid antrum (tympanic antrum, antrum mastoideum, Valsalva's antrum) is an air space in the petrous portion of the temporal bone, communicating posteriorly with the mastoid cells and anteriorly with the epitympanic recess of the middle ear ...

Laryngeal Aditus
The laryngeal inlet (laryngeal aditus, laryngeal aperture) is the opening that connects the pharynx and the larynx. Borders Its borders are formed by: * the free curved edge of the epiglottis, anteriorly * the arytenoid cartilages, the corniculate cartilages, and the interarytenoid fold, posteriorly * the aryepiglottic fold The aryepiglottic folds are triangular folds of mucous membrane of the larynx. They enclose ligamentous and muscular fibres. They extend from the lateral borders of the epiglottis to the arytenoid cartilages, hence the name 'aryepiglottic'. They ..., laterally Additional Images File:Slide2kuku.JPG, Deep dissection of larynx, pharynx and tongue seen from behind File:Slide3kuku.JPG, Deep dissection of larynx, pharynx and tongue seen from behind See also * aditus References * * External links * - (listed as 'Inlet of the larynx') {{Authority control Human head and neck ...
