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

Description

A fetus at 38 weeks of gestation lies curled in the amniotic cavity, seen from behind and slightly above, with the flexed spine, drawn-up knees and crossed limbs of the mature intrauterine posture. The head is large and well developed, covered with dark scalp hair, and the auricle of the external ear is fully modelled with a defined helix and lobule; the hands rest against the face with distinct fingers, while one foot with separated toes is tucked against the trunk. Subcutaneous fat has smoothed the body contours and filled the cheeks, obscuring the rib outlines visible at earlier weeks. The umbilical cord loops around the trunk, its spiral vessels rendered as two umbilical arteries and a single umbilical vein, running to a discoid placenta whose chorionic plate vessels branch across the fetal surface where it implants into the vascular uterine wall. At 38 weeks the pregnancy is term, organ maturation including pulmonary surfactant production is essentially complete, and the fetus is typically settling into a cephalic presentation ahead of labour. Views of this stage support discussion of fetal lie and presentation, engagement, estimated fetal weight, amniotic fluid volume and placental site, all assessed by third-trimester ultrasound. The visible cord loop around the body illustrates nuchal or body cord entanglement, a finding relevant to intrapartum monitoring, while the placental disc and its cord insertion relate to counselling about delayed cord clamping and third-stage delivery of the placenta. The image suits obstetric and midwifery teaching sequences on fetal growth, antenatal classes and clinic waiting-room material, and patient-facing apps that track development week by week. It also serves textbook and journal figures on term fetal anatomy, placental circulation and umbilical cord relationships, and provides publishers and device companies with a consistent term counterpart to earlier stages in the same series.
