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

Description

At 40 weeks of gestation the fetus fills the uterine cavity, shown here curled in the characteristic flexed attitude with the head directed inferiorly in a cephalic presentation. The limbs are drawn close to the trunk, hands near the face and knees flexed toward the abdomen, while the scalp carries visible hair and the external ear, eyelids, fingers and toes are fully formed with defined nails. The umbilical cord loops from the anterior abdominal wall to the fetal surface of the placenta, its two umbilical arteries coiling around the single umbilical vein beneath the amniotic covering. The discoid placenta lies against the uterine wall behind the fetus, its chorionic plate vessels radiating toward the cord insertion, and the translucent amniotic membrane separates the fetus from the myometrium. Term anatomy of this kind underpins assessment of fetal lie, presentation and engagement in late pregnancy, the findings recorded at every third-trimester abdominal palpation and confirmed by ultrasound before delivery planning. Cord coiling, insertion site and placental position are directly relevant to nuchal cord, cord prolapse, velamentous insertion and placenta praevia, while amniotic fluid volume and membrane integrity relate to oligohydramnios and prelabour rupture of membranes. The image also illustrates the maturity expected at term, when surfactant production, subcutaneous fat and vernix support successful transition to extrauterine life. Suitable for obstetric and midwifery teaching on presentation and labour mechanics, antenatal class handouts and patient-facing material explaining what the baby looks like at full term, and for textbook or journal figures on placental and cord anatomy. Publishers, hospital communications teams and pregnancy app developers can use it as part of a week-by-week gestational series with consistent styling.
