| fallopian pregnancy | <obstetrics> An ectopic pregnancy that involves the development of the embryo within the fallopian tube. This can result in a surgical emergency when the developing embryo reaches a critical size. (27 Sep 1997) |

| fallopian tube | <anatomy> The paired tubes which connect the ovaries to the uterus and conduct the egg to the uterus. (27 Sep 1997) |

| fallopian tubes | The fallopian tubes normally transport the egg of the female from the egg sac, or ovary, to the womb, or uterus. Normal tubes have small hair like projections on the lining cells called cilia. These cilia are important to movement of the egg through the fallopian tube and into the uterus. If the tubal cilia are damaged by infection, the egg may not get 'pushed along' normally and can settle in the tube. Likewise, if infection causes partial blockage of the tube with scar tissue, this can also act to prevent the egg from getting to the uterus. Any process that narrows the tube and thus decrease the caliber of the passage way can increase the chance of an ectopic pregnancy. Examples of these would be endometriosis, tumours, or scar tissue in the pelvis (pelvic adhesions) that cause twisting or chinking of the tube. (12 Dec 1998) |
| Fallopius, Gabriel | <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.

| Falloppius, Gabriele | <person> B. Modena, Italy, 1523. Educated for the Church. Studied Medicine at Ferrara and Later at Pisa. In 1551 succeeded Columbus as Professor of Anatomy and Surgery in Padua and also occupied the Chair of Botany. Made many important discoveries, one of them being that of the bony labyrinth of the ear. Added much to the knowledge of the reproductive system. D. Padua, Oct. 9th, 1563. (By Cole et al. Date of death is given as 1562.) Aqueduct of Falloppius - the canal for the facial nerve in the temporal bone. Falloppian Tubes - tubae uterinae. Lived: 1523-1563. (05 Dec 1998) |
| Fallot's tetrad | A congenital heart anomaly which consists of pulmonary stenosis, ventricular septal defect, dextroposition of the aorta (aorta is on the right side instead of the left) and hypertrophy of the right ventricle. This condition results in a blue baby at birth due to inadequate oxygenation. Surgical correction is emergent. (27 Sep 1997) |
| Fallot's triad | Combination of pulmonary valve stenosis and atrial septal defect with right ventricular hypertrophy. (12 Dec 1998) |

| fallow deer | <zoology> A European species of deer (Cervus dama), much smaller than the red deer. In summer both sexes are spotted with white. It is common in England, where it is often domesticated in the parks. Origin: So called from its fallow or pale yellow colour. Source: Websters Dictionary (01 Mar 1998) |
