Human Fetus at 28 Weeks in the Womb, Lateral View (Black Skin)

Description

A fetus at approximately 28 weeks of gestation is shown in lateral profile, lying in the characteristic flexed attitude with the head bowed toward the chest, the spine curved and the hips and knees drawn up. The rounded cranial vault, external ear, upper limb with the hand raised near the face, and the lower limbs with clearly formed feet and toes are all visible through the translucent amniotic membrane. The umbilical cord leaves the anterior abdominal wall at the umbilicus and spirals superiorly and posteriorly through the amniotic fluid toward the placental disc at the upper edge of the field, while the enveloping uterine wall and amniotic sac form the surrounding chamber. Subcutaneous fat has begun to smooth the body contours typical of the third trimester. At 28 weeks the fetus enters the third trimester, a threshold used clinically for viability counselling, corticosteroid administration for lung maturation, and planning of neonatal intensive care in threatened preterm birth. This stage is when surveillance of growth, amniotic fluid volume, fetal lie and presentation becomes routine, and when umbilical artery Doppler studies are used to assess placental function in suspected growth restriction. The depicted cord-to-placenta relationship also underpins discussions of cord insertion, nuchal loops and placental localisation on third-trimester ultrasound. This rendering suits obstetric and midwifery teaching sequences that track fetal development week by week, antenatal class handouts, and pregnancy apps or patient leaflets explaining what is happening in the third trimester. It also serves embryology atlases, journal and textbook figures on fetal growth, and editorial or public-health material on preterm birth and neonatal care.
