From the third week of development until birth, the placenta plays a crucial role in fetal development by providing the fetus with nutrients and eliminating its wastes.

Fetal development during the first 3 months (trimester) of pregnancy is a complex process of organogenesis and the fetus is then especially at risk from developmental defects.

Although radiation doses to a fetus tend to be lower than the dose to the mother, due to protection from the uterus . and surrounding tissues, the human embryo and fetus are sensitive to ionizing radiation at doses greater than 0.1 gray (Gy).

Previous research has revealed that the human fetus responds to sound, but to date there has been little systematic investigation of the development of fetal hearing. The development of fetal behavioural responsiveness to pure tone auditory stimuli (100 Hz, 250 Hz, 500 Hz, 1000 Hz, and 3000 Hz) was examined from 19 to 35 weeks of gestational age fetal brain development. The maternal component of the placenta is the decidua. The fetal placental tissues include the umbilical cord, chorionic villi, amniotic membrane, and chorionic membrane [42,43]. Placental metabolism, placental hormone production, and substrate transport are all essential for fetal development. Norma Baby's Development at 20 Weeks. At 20 weeks, the developing fetus is about 6 inches long (13.2 cm) and may weigh about 10 ounces. The baby may begin to make movements that the mother can feel at about 19 to 21 weeks; this baby movement is termed quickening. The baby at this stage of development can move its facial muscles, yawn, and suck its. Maternal nutrition plays a critical role in fetal growth and development.

Developing the Tools to Study the Brain in Utero. Most of what scientists know about fetal brain development comes from looking at animal brains or analyzing human postmortem samples. 5 This research has provided insights on the development of brain structure but offers few clues about how functional systems become organized. The earliest investigations of human fetal brain function date back. The slow but sure development of the fetus inside a woman's body should be monitored to ensure the delivery of a healthy and safe baby.
