| Gabriel Fallopius | <person> Italian anatomist. Fallopius (Fallopio) of Modena, a loyal pupil of Vesalius and successor of the Chair at Padua (1551) discovered and described the ovaries, tubes (Fallopian), vagina, placenta, chorda tympani, and the fifth, sixth, and ninth cranial nerves. Although his name is attached to many subjects (Fallopio's pyramidalis muscle, Fallopius nerve, Fallopian aqueduct, Fallopio's seminal vesicles, Fallopian hiatus, Fallopius valve, ligament of Fallopio), he is eponymously remembered by the oviducts or Fallopian tubes. He wrote fluently on syphilis, surgery, diet and anatomy. Fallopius' great work was the "Observations in Anatomy," which corrected some errors in the "Fabrica," and was first published in Venice in 156l. This text is acclaimed to be the second best anatomy (behind the Fabrica). Fallopius, at the age of 24, became Professor of Anatomy at Ferrara, then in 1548 at Pisa, and finally at Padua in 1551, where he was followed by his pupil, Gerolamo Fabrizio d 'Acqueperdente, better known by the name Fabricius. Lived: 1523-1562. See: fallopian aqueduct, fallopian arch, fallopian canal, fallopian hiatus, fallopian ligament, fallopian neuritis, fallopian pregnancy, fallopian tube, aqueductus fallopii, tuba fallopiana, fallopian tube.

| aqueduct | 1. A conductor, conduit, or artificial channel for conveying water, especially one for supplying large cities with water. The term is also applied to a structure (similar to the ancient aqueducts), for conveying a canal over a river or hollow; more properly called an aqueduct bridge. 2. <anatomy> A canal or passage; as, the aqueduct of Sylvius, a channel connecting the third and fourth ventricles of the brain. Origin: F. Aqueduc, OF. Aqueduct (Cotgr), fr. L. Aquaeductus; aquae, gen. Of aqua water + ductus a leading, ducere to lead. See Aqua, Duke. Source: Websters Dictionary (01 Mar 1998) |
| aqueduct of cerebrum | An ependymal-lined canal in the mesencephalon about 20 mm long, connecting the third to the fourth ventricle. Synonym: aqueductus cerebri, aqueduct of cerebrum, aqueductus sylvii, iter a tertio ad quartum ventriculum, sylvian aqueduct. (05 Mar 2000) |
| aqueduct of sylvius | A canal between two of the cavities (called the third and fourth ventricles) in the brain through which cerebrospinal fluid passes. (12 Dec 1998) |
| aqueduct veil | A membrane obstructing the sylvian aqueduct, causing a noncommunicating hydrocephalus. (05 Mar 2000) |
| vein of cochlear aqueduct | It drains the cochlea, sacculus, and part of the utricules, and empties into the superior bulb of the jugular vein by accompanying the perilymphatic duct through the cochlear canaliculus. Synonym: vena aqueductus cochleae, vein of cochlear aqueduct, vena canaliculi cochleae. (05 Mar 2000) |

| Cotunnius' aqueduct | aqueduct of vestibule |
| sylvian aqueduct | Aqueduct of vestibule, a bony canal running from the vestibule and opening on the posterior surface of the petrous portion of the temporal bone, giving passage to the endolymphatic duct and a small vein. Synonym: aqueductus cotunnii, aqueductus vestibuli, Cotunnius' aqueduct, Cotunnius' canal, cerebral aqueduct. (05 Mar 2000) |
| opening to cerebral aqueduct | Entrance to the cerebral aqueduct (of Sylvius) from the caudal part of the third ventricle. Synonym: aditus ad aqueductum cerebri, Bartholin's anus, opening to cerebral aqueduct. (05 Mar 2000) |
| external aperture of vestibular aqueduct | The external opening of the vestibular aqueduct on the posterior surface of the petrous part of the temporal bone near the groove for the sigmoid sinus. Synonym: apertura externa aqueductus vestibuli. (05 Mar 2000) |
