fallopian tube

 [fah-lo´pe-an]
a slender tube extending laterally from the uterus toward the ovary, one on each side, allowing passage of ova to the cavity of the uterus and of spermatozoa in the opposite direction. Called also uterine tube and oviduct.

When the mature ovum leaves the ovary it enters the fringed opening of the fallopian tube, through which it travels slowly to the uterus. When conception takes place, the tube is usually the site of fertilization. Obstruction or infection within the fallopian tubes is a major cause of infertility. The removal of one tube by surgery, or the failure of a tube to function, ordinarily leaves the other tube intact and able to perform its function in reproduction. Occasionally the fertilized ovum implants in the wall of the fallopian tube, resulting in an ectopic, or tubal pregnancy.
Fallopian tube. From McKinney et al., 2000.

1995, two colonies, 5 mm high, gonophores observed [N 1794]; Mar Grande--Coroa Beach, on biogenic rock, 4m depth, 20.
Young ones light brown, elongated, 650-712 [micron]m long, pedicel of 3-4 rings, usually on stolon, but sometimes on erect shoot in axil; wide in centre, about 310 [micron]m in diamenter, and sometimes at terminal end, tapering below, 230 [micron]m wide; gonophores with 1 or 2 rows of developing medusae.
1993, eighteen colonies, 5mm high, gonophores observed [N 1806]; Northern Coast, Arembepe region, on embayment beach rock bank, 3-4 m depth, 15.
After the gonotheca was cut open with a thin needle, the star-shaped embryos and preactinulae were picked up with the needle from the dissociated gonophores.
The colonies were basically dioecious, although bisexual polyps were occasionally observed; the form of the gonophores was very variable under laboratory culture conditions.
The number of gonophores gradually decreased during the 2 months after collection.
