Human Fetus at 38 Weeks in the Womb (Black Skin)

Description

A fetus at 38 weeks of gestation lies within the uterine cavity in a flexed, head-down (cephalic) attitude, the vertex directed toward the lower uterine segment and the spine curved along the maternal left. The limbs are drawn into the trunk, with the hands close to the face and the knees and feet held near the abdomen, reflecting the limited space of the term amniotic cavity. Scalp hair, a formed external ear with defined helix and lobule, plump subcutaneous fat and well-developed digits with nails indicate maturity. The umbilical cord, its coiled vessels visible as paired arteries and a single vein, passes from the abdominal insertion toward the placenta, whose chorionic surface and vascular pattern are seen against the richly perfused myometrium and uterine vasculature. At 38 weeks the pregnancy is regarded as full term, with organ systems, surfactant production and thermoregulatory fat stores prepared for extrauterine life. The depicted cephalic presentation is the orientation favourable for vaginal delivery, and this anatomy underpins clinical assessment of lie, presentation and engagement by Leopold manoeuvres and ultrasound. Cord position relative to the fetal neck and limbs is relevant to discussions of nuchal cord and cord compression, while the placental disc and its uterine attachment are the reference anatomy for placental location, third-stage delivery and postpartum haemorrhage risk. The image supports obstetric and midwifery teaching on term fetal anatomy, presentation and placental relationships, and complements the earlier second-trimester images in this series for demonstrating growth across gestation. It suits antenatal education leaflets, birth-preparation classes, hospital and clinic displays, textbook and journal figures, and app or web content explaining what happens in the final weeks before labour.
