Human Fetus at 32 Weeks in the Womb (Brown Skin)

Description

A fetus of approximately 32 weeks gestation lies in a flexed attitude within the intact amniotic sac, suspended in amniotic fluid and enclosed by the vascularised uterine wall. The head is turned in profile, showing well-formed eyelids, nose and lips, a fully modelled external ear (auricle) and fine scalp hair. Subcutaneous fat has smoothed the contours of the trunk and limbs, the thighs and knees are drawn up against the abdomen, and the hands and feet are clearly digitated. The coiled umbilical cord passes from the umbilicus toward the placenta, whose disc-shaped, richly perfused surface is visible along the posterior uterine lining behind the fetal back. The third trimester is the period of rapid weight gain, brown and white fat deposition, surfactant maturation and completion of pulmonary alveolar development, all of which shape neonatal outcomes if delivery occurs early. Views such as this support discussion of fetal presentation and lie, amniotic fluid volume assessment, placental position and cord anatomy, all of which are routinely evaluated at third-trimester ultrasound. The proportions shown are also the reference for symphysis-fundal height measurement, biometry-based growth charts, and counselling on late preterm birth around 32 weeks. Suitable for obstetric and midwifery teaching, embryology and developmental anatomy atlases, antenatal class and patient-education material explaining fetal position and placental function late in pregnancy, and editorial or publication figures on prenatal growth. As one frame in a week-by-week gestational series, it allows educators, publishers and device companies to show continuity of fetal development from the second into the third trimester.
