Human Fetus at 35 Weeks in the Womb (Caucasian Skin)

Description

At 35 weeks of gestation the fetus fills most of the uterine cavity, shown here flexed in the classic curled attitude with the chin tucked, knees drawn to the abdomen and one hand raised beside the cheek. The translucent amniotic sac encloses a thinning volume of amniotic fluid, and the umbilical cord, its twisted vein and paired arteries visible through the surface, courses from the placental disc across the fetal face toward the abdominal insertion. Behind the fetus the placenta appears as a thick, richly vascular plate applied to the uterine wall, whose myometrium and subserosal vessels frame the whole cavity. Subcutaneous fat has smoothed the limbs and face, the eyelids are closed, and fine detail of the fetal hand and foot is preserved. By this stage the lungs are producing surfactant, the fetus has assumed a stable presentation, and weight gain accelerates in preparation for birth, making week 35 a reference point for late preterm counselling. The image supports discussion of fundal height and symphysis–fundus measurement, amniotic fluid volume assessment, cord position and nuchal loops, and placental location relative to the uterine wall. Reduced space accounts for the strong flexion and the decline in amplitude of fetal movements that patients often report, while the vascular placental interface underlies exchange concerns in growth restriction and preeclampsia. Suitable for obstetric and midwifery teaching on the third trimester, antenatal class materials, patient-facing leaflets explaining fetal position and cord anatomy near term, and textbook or journal figures in a serial developmental sequence alongside earlier gestational weeks. Ultrasound training resources and hospital or clinic websites can use it to give parents a recognisable picture of the near-term uterus.
