ovule
A structure found in higher plants that contains an egg cell and develops into a seed after fertilization.
ootype Part of oviduct in flatworms that receives ducts from vitelline glands and Mehlis' gland.
Opalinata The protozoan subphylum where members are cylindrical; covered with cilia. Examples: Opalina, Zelleriella.
(Tuba Uterina [Fallopii]; Fallopian Tube; Oviduct)
The uterine tubes (Figs. 1161, 1165) convey the ova from the ovaries to the cavity of the uterus.
After fertilization, when the egg is still in the oviduct, it begins to divide by mitosis to form a hollow fluid filled ball of cells called the blastula. This process is called cleavage.
This shape results from the egg being forced through the oviduct. Muscles contract the oviduct behind the egg, pushing it forward. The egg's wall is still shapeable, and the pointy end develops at the back side.
Fertilization, the fusion of the sperm and egg, usually occurs in the upper third of the oviduct. Thirty minutes after ejaculation, sperm are present in the oviduct, having traveled from the vagina through the uterus and into the oviduct.
ectopic pregnancy - implantation of the embryo in the oviduct or other site outside the uterus typically caused by failure of zona pellucida to keep blastocyst from adhering to oviduct walls; ...
[L. albus - white]. In reference to development, the egg white of birds eggs formed in the oviduct before the addition of the shell. It provides protein and water to the developing embryo and protection from microorganisms.
In Drosophila (fruit flies), the chorion (eggshell) gene is copied many times in certain cells of the oviduct. These cells make large quantities of the protein needed to surround the egg.
Origin: L., Gr. Hystera A hollow muscular organ in the pelvic cavity of females; contains the developing fetus.An enlarged section of the oviduct where the embryo has enough space to develop. The uterus is also known as the womb in humans.
In humans, for example, motile cilia are found in the lining of the trachea or windpipe, where they sweep mucus and dirt out of the lungs. In the oviducts, the beating of cilia moves the ovum from the ovary to the uterus.
that can beat in synchrony causing the movement of unicellular paramecium. Cilia are also found in specialize linings in eukaryotes. For example, cilia sweep fluids past stationary cells in the lining of trachea and tubes of female oviduct.
