Human Fetus at 37 Weeks in the Womb (Black Skin)

Description

A fetus of approximately 37 weeks' gestation lies in the amniotic cavity in the characteristic flexed attitude of late pregnancy, spine curved, hips and knees drawn up and the arms folded across the chest so that the hand and fingers rest near the face. The head is turned to show the ear and a covering of scalp hair, and the plantar surface of one foot with distinct toes is presented toward the viewer. The umbilical cord loops across the fetal trunk and thigh, its two umbilical arteries and single umbilical vein indicated by contrasting colours as they run toward the fetal surface of the discoid placenta. The placenta is seen implanted against the uterine wall superiorly, its chorionic plate and vascular tree partly visible, with the surrounding myometrium and decidua enclosing the space. At 37 weeks the pregnancy has reached early term, and this attitude of universal flexion is the configuration that determines the presenting diameters at the pelvic inlet. The illustration supports discussion of fetal lie, presentation and engagement, of cord position and the risk of nuchal or body cord loops, and of placental site as assessed on third-trimester ultrasound. Near-term anatomy is also the reference point for teaching about amniotic fluid volume, fetal growth assessment, biophysical profile scoring and the umbilical artery Doppler waveform used to evaluate placental function. The rendering suits obstetric and midwifery teaching resources, antenatal class material and patient-facing handouts explaining what the baby looks like in the final weeks before birth. It works as an atlas or textbook figure on late fetal development, as a reference for ultrasound training modules on presentation and cord anatomy, and as part of a gestational series when shown alongside earlier second-trimester stages.
