Clear Visualization of the Fetal Body at Gestational Week 22

Description

Positioned within the amniotic cavity, a human fetus at approximately 22 weeks’ gestation is shown with the head flexed and the trunk elongated, the upper limbs lying anterior to the thorax and the lower limbs extending inferiorly toward the uterine fundus. The umbilical cord courses from the fetal umbilicus to the placental disc, where chorionic vessels spread across the fetal surface before entering the placenta. Surrounding membranes outline the amniotic sac, framing the conceptus against the uterine environment. At 22 weeks, fetal proportions have shifted from early embryonic patterns to a more recognizable neonatal silhouette, and this stage aligns with common anatomic survey windows in obstetric ultrasound where long bones, spine, and abdominal wall integrity are assessed. This view also supports teaching on placental location and cord insertion, practical when discussing placenta previa screening, vasa previa risk with velamentous insertion, or cord abnormalities such as a single umbilical artery. Gestational dating and growth assessment hinge on these relationships. Small details matter. Use this artwork in embryology and human development courses to anchor week-specific milestones, or in obstetrics and maternal-fetal medicine materials illustrating normal second-trimester anatomy, the amniotic sac, placenta, and umbilical cord configuration. It also fits patient education handouts explaining fetal growth at the mid-pregnancy anatomy scan. Anatomical accuracy verified by SciePro's Medical Advisory Board.
