Oviduct Definition and Examples - Biology Online Dictionar

In amphibians and lungfishes, the oviduct is a simple ciliated tube, lined with mucus -secreting glands that produce the jelly that surrounds the ovum. In all other vertebrates, there is normally some degree of specialisation of the tube, depending on the type of eggs produced From Longman Dictionary of Contemporary English o‧vi‧duct /ˈəʊvidʌkt $ ˈoʊvə-/ noun [ countable] technical one of the two tubes in a woman or female animal through which eggs pass to the womb Examples from the Corpus oviduct • The female bot fly holds her eggs in her oviduct until they have hatched into maggots In oviparous animals, the passage from the ovaries to the outside of the body is known as the oviduct. The eggs travel along the oviduct. These eggs will either be fertilized by spermto become a zygote, or will degenerate in the body

A tube through which eggs or egg cells (oocytes) are carried to the uterus in mammals or to the outside of the body in other animals. The fallopian tubes are oviducts. 0 oviduct The tube that conveys an animal egg cell from the ovary to other parts of the reproductive system or to the outside. Eggs are passed along the oviduct by the action of muscles and cilia oviduct tube to carry eggs from the ovary Source: Noland, George B. 1983. General Biology, 11th Edition.St. Louis, MO. C. V. Mosby oviducts Tubes that connect the ovaries and the uterus; transport sperm to the ova, transport the fertilized ova to the uterus, and serve as the site of fertilization; also called the fallopian tubes or uterine tubes. . PICT The solid yellow circles indicate the terminus of the oviducts near the ovaries. Called a fallopian tube in humans, the oviduct receives the egg from the ovary at ovulation. Cilia in the lining of the oviducts propel the eggs to the horns of the uterus Each oviduct is about 10 cm (4 in) long and has a diameter about the size of a drinking straw. An oviduct can be divided into several regions along its length (Figure 2.2). Nearest the ovary is a funnel-shaped portion, the oviductal infundibulum. The opening into the infundibulum, into which the ovulated egg enters, is the ostium

Oviduct The oviduct (Fallopian tube) is a tubular organ, interconnecting the ovary with the uterus. The oviduct has four segments: infundibulum with fimbria, ampulla (site of fertilization), isthmus and intramural. The oviduct transports the secondary oocyte and sperm to the site of fertilization and the embryo toward the uterus Richard E. Jones PhD, Kristin H. Lopez PhD, in Human Reproductive Biology (Fourth Edition), 2014 Oviducts. The oviducts are paired tubes extending from near each ovary to the top of the uterus (Figure 2.2).They are also called fallopian tubes, after the sixteenth-century anatomist Fallopius.Each oviduct is about 10 cm (4 in) long and has a diameter about the size of a drinking straw The Fallopian tubes, named after Gabriel Fallopius, also known as oviducts, uterine tubes, and salpinges are two very fine tubes lined with ciliated epithelia, leading from the ovaries of female mammalsinto the uterus, via..

In mice, the uterus and oviduct meet in a structure called the uterotubal junction (UTJ), which significantly reduces the number of spermatozoa reaching eggs. The flow in the UTJ is bidirectional. After coitus, spermatozoa must move up to reach the eggs and, after gamete fusion. The very active fimbriae, end of the oviduct picks up the ovum. If fertilized ovum or zygote undergoes cleavage and makes its way to the uterus for implantation. If not fertilized, it degenerates within 24 hours

The lateral ends of the oviducts flare out into a trumpet-like structure and have a fringe of finger-like projections called fimbriae, illustrated in Figure 24.10 b As there is no direct connection between the ovaries and fallopian tubes (also known as uterine tubes or oviducts), the egg is transported to the uterus in a peritoneal fluid produced by the..

oviduct Definition from the Biology topic Biolog

The oviduct is a twisted tube that is 25 to 27 inches long when fully developed and is divided into five major sections. These sections are the infundibulum, magnum, isthmus, shell gland, and vagina. The first part of the oviduct, the infundibulum (or funnel) is 3 to 4 inches long and engulfs the ovum released from the ovary Human gestation. Twenty-four hours before fertilization, the egg has finished meiosis and become a mature oocyte. When fertilized (at conception), the egg, now known as a zygote, travels through the oviduct to the uterus Tools Fertilization is the process by which eggs and spermatozoa interact, achieve mutual recognition, and fuse to create a zygote, which then develops to form a new individual, thus allowing for the continuity of a species

The portion of the oviduct in which the eggs or embryos mature is called the uterus. Mammalian eggs are fertilized in the fallopian, or uterine, tubes, which are situated above the uterus. The terminal portion of the oviduct in organisms marked by internal fertilization (with the oviduct opening to the exterior) is called the vagina The mammalian oviduct is the venue of important events leading to the establishment of pregnancy. These events include final maturation and transport of the female and male gametes, fertilization, early cleavage-stage embryonic development, and transport of the embryo to the uterus

Menstruation is a natural process that is part of a woman's reproductive health. To learn why it happens and how it fits into the menstrual cycle, check out this lesson Introduction. Transit through the oviduct is driven by two major mechanisms: smooth muscle contraction and ciliary activity. Although the relative importance of these mechanisms is still not fully clear, several lines of evidence indicate that ciliary action may play a dominant role in the transport of the gametes and the embryo [].Supportive of this notion, pharmacological inhibition of. The epithelial cells in the female reproductive tract play many important roles, including secreting hormones and growth factors. You can find epithelia, the plural for epithelium tissue, in a woman's ovaries, uterus and oviduct. The cells can secrete different hormones, cytokines and other substances that influence reproduction and health The uterus (from Latin uterus, plural uteri) or womb (/ w uː m /) is a major female hormone-responsive secondary sex organ of the reproductive system in humans and most other mammals.Things occurring in the uterus are described with the term in utero.In the human, the lower end of the uterus, the cervix, opens into the vagina, while the upper end, the fundus, is connected to the fallopian. The egg is moved slowly down the oviduct by fluids and the muscles in the oviduct walls. If the egg is fertilised while in the oviduct, it will form a zygote, which then forms an embryo, a foetus, and finally, a baby. The uterus wall (endometrium) thickness will be maintained until birth

Twenty-four hours before fertilization, the egg has finished meiosis and becomes a mature oocyte. When fertilized (at conception) the egg becomes known as a zygote. The zygote travels through the oviduct to the uterus (Figure 1). The developing embryo must implant into the wall of the uterus within seven days, or it will deteriorate and die Muscles contract the oviduct behind the egg, pushing it forward. The egg's wall is still shapeable, and the pointed end develops at the back. Long, pointy eggs are an incidental consequence of having a streamlined body typical of birds with strong flying abilities; flight narrows the oviduct, which changes the type of egg a bird can lay From the ovary arises a short oviduct. In the middle one-third of the body on each side are small follicles of vitelline glands. Small ducts arise from vitelline glands to form two transverse vitelline ducts which unite to form a small common vitelline duct It is the process of Fusion of sperm and ovum to form Zygote.

DEVELOPMENTAL BIOLOGY 3230: Cleavage refers to the stereotyped pattern of early mitotic divisions that divides up the large volume egg cytoplasm. The early zygote is unique in being so large. Most cells undergo a period of growth between cycles of mitosis, but this is not true for early cleavage stage blastomeres The Strongyloides stercoralis life cycle is complex, alternating between free-living and parasitic cycles and involving autoinfection.In the free-living cycle: Rhabditiform larvae are passed in the stool of an infected definitive host , develop into either infective filariform larvae (direct development) or free-living adult males and females that mate and produce eggs , from which. Within the brain, ciliated epithelium cells move cerebral spinal fluid. Within the oviduct, these cells transport the egg from the ovary to the uterus. In the respiratory tract, ciliated epithelial cells move mucous that contains dust and bacteria out of the body The eggshell of the chicken consists of a bi-layered shell membrane overlaid with a thick, calcified shell matrix.
