Fetus at Week 20 - Brown Skin

Description

Fetus at 20 weeks’ gestation appears alongside a discoid placenta and a single umbilical cord against an isolated black field. The cord inserts at the fetal umbilicus on the anterior abdominal wall, then courses to the fetal surface of the placenta where branching chorionic vessels spread radially beneath the amnion. Limb buds have matured into well-formed upper and lower extremities, with the hands and feet positioned close to the trunk in a typical flexed fetal posture and the head proportionally large relative to the thorax and abdomen. Brown fetal skin tone is presented across the face, trunk, and limbs. Week 20 sits in the core of the second trimester, the time point targeted by the standard mid-trimester anatomy survey and many counseling conversations in prenatal care. Seeing the placenta and cord in the same frame helps orient learners to fetoplacental circulation and to clinically important variants at this stage, including marginal or velamentous cord insertion, single umbilical artery, and placental morphology relevant to placenta previa screening and fetal growth restriction workups. Lighting and isolation emphasize surface landmarks, so the umbilical insertion, placental disc margins, and cord trajectory read immediately without competing maternal anatomy. Use this illustration in embryology and obstetrics teaching when introducing second-trimester fetal proportions, placental anatomy, and the physical basis for Doppler and ultrasound assessments. It also fits patient-facing prenatal education materials and textbooks that require inclusive representation of fetal skin tone while keeping the placenta and umbilical cord anatomically coherent in one image.
