Fetus at Gestational Week 14

Description

Curled in a flexed fetal posture, the conceptus is shown at approximately 14 weeks’ gestation with the head disproportionately large relative to the trunk, a well-defined face, and long bones that now read clearly through the limb contours. Upper limbs lie anterolateral to the thorax with separated fingers, while the lower limbs flex at hip and knee with distinct toes oriented inferiorly. A coiled umbilical cord courses from the fetal umbilicus to a discoid placenta, whose fetal surface texture suggests the chorionic plate and branching chorionic vessels beneath a thin membrane. Semi-translucent skin permits subtle visualization of superficial venous patterning. This gestational window matters because limb segmentation and digital separation are far enough along to support screening for reduction defects, while the cord-placenta relationship provides a clear teaching correlate for early second-trimester Doppler and anatomy survey concepts. Cord coiling and insertion are common points of discussion in obstetrics, since marginal or velamentous insertion and abnormal coiling have associations with growth restriction and intrapartum compromise, and they are also frequent sources of confusion when learners first translate 3D anatomy to ultrasound. The placental disc at this stage remains relatively compact, so spatial relationships are easy to grasp. Use this rendering for embryology and human development modules, obstetrics teaching files, and patient-facing materials that explain how the fetus connects to the placenta via the umbilical cord at the end of the first trimester and start of the second. It also fits well in medical publishing layouts covering prenatal screening, placental anatomy, and gestation timelines. Anatomical accuracy verified by SciePro's Medical Advisory Board.
