| 单词 | uterine tube |
| 例句 | Rather than a fallopian tube, he said, “uterine tube just makes more sense — it tells you what it is.” Should Medicine Still Bother With Eponyms? 2023-06-19T04:00:00Z The nearby uterine tube, either left or right, receives the oocyte. Anatomy and Physiology 2013-06-19T00:00:00Z Current flowing toward the uterus is generated by coordinated beating of the cilia that line the outside and lumen of the length of the uterine tube. Anatomy and Physiology 2013-06-19T00:00:00Z If the oocyte is successfully fertilized, the resulting zygote will begin to divide into two cells, then four, and so on, as it makes its way through the uterine tube and into the uterus. Anatomy and Physiology 2013-06-19T00:00:00Z If the egg is not fertilized, it will simply degrade—either in the uterine tube or in the uterus, where it may be shed with the next menstrual period. Anatomy and Physiology 2013-06-19T00:00:00Z The isthmus is the narrow medial end of each uterine tube that is connected to the uterus. Anatomy and Physiology 2013-06-19T00:00:00Z So how do they travel into the uterine tube and toward the uterus? Anatomy and Physiology 2013-06-19T00:00:00Z The ovulated oocyte with its surrounding granulosa cells is picked up by the infundibulum of the uterine tube, and beating cilia help to transport it through the tube toward the uterus. Anatomy and Physiology 2013-06-19T00:00:00Z Fertilization occurs within the uterine tube, and the final stage of meiosis is completed. Anatomy and Physiology 2013-06-19T00:00:00Z Fertilization must occur in the distal uterine tube because an unfertilized oocyte cannot survive the 72-hour journey to the uterus. Anatomy and Physiology 2013-06-19T00:00:00Z As it is swept along the distal uterine tube, the oocyte encounters the surviving capacitated sperm, which stream toward it in response to chemical attractants released by the cells of the corona radiata. Anatomy and Physiology 2013-06-19T00:00:00Z High concentrations of estrogen that occur around the time of ovulation induce contractions of the smooth muscle along the length of the uterine tube. Anatomy and Physiology 2013-06-19T00:00:00Z Implantation in a uterine tube causes bleeding, which appears to stimulate smooth muscle contractions and expulsion of the embryo. Anatomy and Physiology 2013-06-19T00:00:00Z If diagnosis is late and the uterine tube is already ruptured, surgical repair is essential. Anatomy and Physiology 2013-06-19T00:00:00Z |
