Fetus at Week 21 - Asian Skin

Description

Fetus at 21 weeks’ gestation is shown with the placenta and an intact umbilical cord, allowing the fetal-placental unit to be read as a single anatomic specimen. From this fixed external perspective, the craniofacial profile, thorax, abdomen, and flexed limbs are proportioned for the second trimester, with the head still relatively large compared with the trunk and the extremities clearly segmented into arm, forearm, hand and thigh, leg, foot. The umbilical cord courses from the fetal umbilicus to its placental insertion, and the placental disc sits adjacent to the fetus in the same field against a white background. Asian skin tone is represented across the fetal integument. Week 21 sits within the standard window for the mid-trimester anatomic survey, when clinicians correlate external morphology with sonographic biometry and organ screening. This illustration helps orient learners to normal second-trimester proportions and to the spatial relationship between fetal abdomen, umbilical ring, and cord, a useful anchor when discussing single umbilical artery, omphalocele, gastroschisis, or abnormal cord insertion patterns such as marginal or velamentous insertion. Placental size and cord length are easy to appraise in this isolated layout, supporting conversations about fetal growth restriction, placental insufficiency, and the downstream implications for antenatal surveillance. One frame, no distractions. Use this illustration in embryology and obstetrics teaching decks to bridge developmental milestones with the second-trimester exam, or in patient-facing educational materials explaining placental and umbilical cord anatomy during routine prenatal care. It also suits textbooks and review articles covering normal human development at 21 weeks and common structural anomalies encountered at the anatomic scan.
