Human Fetus at 40 Weeks in the Womb (Asian Skin)

Description

The fetus is shown at term, lying in a flexed attitude within the uterine cavity with the head presenting toward the lower uterus and the spine curved along the uterine wall. Subcutaneous fat has smoothed the body contours, the scalp is covered with dark hair, the auricle of the external ear is fully formed with firm cartilage, and the nails reach the tips of the fingers and toes. The umbilical cord spirals from the anterior abdominal wall to the placental disc seen at upper left, its two umbilical arteries and single umbilical vein rendered in contrasting colour beneath the amniotic covering. The placenta shows its maternal surface and branching chorionic vasculature against the vascularised endometrial lining. At 40 weeks the fetus has reached full maturity of the pulmonary, thermoregulatory and neurological systems, and this depiction illustrates the anatomy that governs labour and delivery: fetal lie, presentation, attitude and the relationship between cord, placenta and uterine wall. The image supports discussion of cephalic versus breech presentation, nuchal or looped cord, cord length and coiling, placental site and the mechanics of the third stage of labour. It is also a reference point for antenatal assessment of fetal growth, amniotic fluid volume and placental position by ultrasound, and for counselling around post-term pregnancy and induction of labour. The rendering suits obstetric and midwifery teaching, prenatal classes and antenatal clinic displays, textbook and atlas figures on fetal development milestones, and patient-facing material explaining what a baby looks like at term. It works as the final panel of a gestational timeline series alongside earlier second-trimester stages, and is well suited to publishers, health education agencies and medical device or perinatal care communications.
