Physiologic Changes in Pregnancy 3. Embryonic Development. In this stage, the fetus is nearly 1” long and is surrounded by a somewhat egg-shaped vesicle that measures 1” to 1 ½” in length. Define zygote. This graphic looks at six key hormones during pregnancy, their roles in the development of the baby, and other effects.

Organs begin forming. • Blood flows in the baby’s veins, separate from his mother’s blood.

Normal Fetal Development and Factors Affecting Teratogenicity 2. The changes in the embryo’s appearance will continue rapidly from this point until birth. While the inner layer of embryonic cells is busy forming the embryo itself, the outer layer is forming the surrounding protective environment that will help the embryo survive the pregnancy. Use the key choices to identify the embryonic stage or process described below. This fact sheet talks about the critical periods of development and types of birth defects that can result from exposures at different stages of pregnancy. 6. •Spontaneous abortion (miscarriage) occurs. Human chorionic gonadotropin (hCG) hCG is an important hormone in early pregnancy. Oocyte is only viable for ~ 24 hours. & Embryonic Development 1. Embryo: from the third through the eighth week major organs develop at eight weeks, organism is less than 2˝ long 3) Fetus: From the Ninth Week Until Birth Sex organs develop Brain development is significant Age of viability occurs around 22 weeks The Third Month the fetus has all its body parts weighs approximately 3 ounces, about 3 inches long growth is rapid fetus is too small survive outside … Key: a. cleavage c. zygote e. blastula Fetus: A term used to describe a growing pregnancy from the third month until birth. 1. Intrauterine bacterial infection and fetal outcomes (1,300 words, 25 refs) The majority of early preterm births are associated with intrauterine infection, which triggers an inflammatory response believed to result in preterm labor (PTL) and injury to the developing fetal lung and brain. Embryonic and fetal growth and development 1. In this lecture I will talk about week 3of embryonic development (GAweek 5). I will cover concepts including early placentation, gastrulation and embryonic folding. Objectives Germ layers Understand the process early placentation, villi formation Understand broadly the events of week 3 of human development Understand the process of gastrulation Download, print, and copy all supplemental documents for student use. For obstetricians pregnancy lasts 280 days or 40 weeks. Embryonic Development Review Sheet 44 321 Developmental Stages of Sea Urchins and Humans 1. Aims • To demonstrate that during the embryonic phase of development the human conceptus is supported by histiotrophic nutrition from the endometrial glands • To present evidence that the yolk sac is important for the uptake of nutrients during embryogenesis • To propose that the histiotrophic form of nutrition may protect the embryo from oxygen free radical mediated teratogenesis Including Pregnant PowerPoint charts & diagrams, newborn PowerPoint template , Fetus ppt template and other Pregnancy PowerPoint Templates. To improve the output of OPU-IVP-ET, the identification and selection of quality oocyte high-donors and embryo recipients as well as improved culture systems, resulting in improved embryo development and pregnancy rates, would make these technologies even more attractive. levels peak at 8 to 10 weeks of pregnancy, then decline and are lower for rest of pregnancy; 1-2 months: 5,000-200,000 mIU/ml; Non-pregnant females: <5.0 mIU/ml; Postmenopausal females: <9.5 mIU/ml) Later in development placenta will secrete hCG Female Reproductive System 3. At this point, the menstrual period is missed. Being susceptible to the effects of teratogens is high during embryonic development. Which organ is the first to form in the developing human fetus, formed after just 1 month of pregnancy?
