:A non-invasive technique for visualizing and prenatal diagnosis of several features of development including: follicles in the ovaries, the gestational sac, fetus in the [[#uterus|uterus]], fetal parameters, and the placenta. The technique uses high-frequency sound waves that are reflected off internal structures. These reflections can then be analysed and displayed by computer. Modern ultrasound machines can also carry out 3 dimensional reconstructions and measure "flow" (blood) using doppler measurements.

===uterus===  
===uterus===  


:The female internal genital (reproductive) tract forming a hollow muscular walled organ, embryonically derived from the [[P#paramesonephric|paramesonephric ducts]]. The human uterus has two uterine tubes (fallopian tubes, oviducts) where the first week of development occurs and a single hollow body where implantation of the blastocyst normally occurs. Following puberty, the non-pregnant uterus (epithelium and underlying stroma) undergoes cyclic changes under the influence of hormones, the menstrual cycle. This cycle of uterine changes ceases during pregnancy. In other species females of non-primate vertebrates (eg rats, mice, horses, pig) have a reproductive cycle called the estrous cycle (oestrous, British spelling). In pregnancy, the uterus contributes the maternal component of the placenta.
