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

Description

A fetus of approximately 35 weeks gestation lies in a flexed, head-down attitude within the translucent amniotic sac, seen from the left side. The head is well developed and covered with scalp hair, the auricle of the external ear is fully modelled with a defined helix, and the eyelids are closed over the orbits. The upper limb is drawn across the chest with the hand near the face, while the knee and lower limb are folded toward the abdomen in the characteristic fetal posture that conserves space in the late third trimester. The umbilical cord emerges from the abdomen and spirals posteriorly, its paired umbilical arteries and single umbilical vein visible through the cord surface, coursing through amniotic fluid toward the vascular uterine wall. At 35 weeks the fetus has accumulated substantial subcutaneous fat, giving the smooth rounded body contour and pink skin tone shown here, and lung maturation with surfactant production is well advanced though not yet complete. Views of this stage support discussion of late preterm birth, fetal lie and presentation, engagement in the maternal pelvis, and the reduced amniotic fluid volume relative to fetal size. The rendering also illustrates landmarks assessed on third-trimester ultrasound biometry and cord Doppler studies, including cord position relative to the fetal neck and limbs, and the interface between amniotic membrane and myometrium relevant to membrane rupture. The image suits obstetric and midwifery teaching sequences on trimester-by-trimester development, antenatal classes and patient-facing material explaining what the baby looks like near term, and textbook or journal figures on fetal growth and positioning. Sonographers, neonatal nurses and childbirth educators can use it alongside the other weeks in this series to build a continuous visual timeline of gestation.
