Fetus at Week 23 - Caucasian Skin

Description

Fetus at gestational week 23 is presented with the placenta and a single umbilical cord, allowing the fetal body to be read in relation to the fetoplacental unit in one fixed frame. Proportions at this stage typically show a relatively large cranium with a smaller face, well-formed auricles, and fully separated fingers and toes with defined nail plates; flexion at the hips and knees often dominates the alternative pose. The umbilical cord courses from the fetal umbilicus to the placental disc, where the chorionic plate surface and cord insertion can be appreciated against the white background. Caucasian skin tone is used while preserving standard surface landmarks such as eyelids, nares, and external genital region contours without assigning sex. Week 23 sits near the threshold where neonatal viability becomes a counseling topic, so accurate external maturity cues matter for teaching obstetric dating and correlating with ultrasound biometry. At this gestation, clinicians also focus on placental function and umbilical cord integrity because fetal growth restriction, velamentous cord insertion, and vasa previa trace back to placental and cord anatomy rather than the fetus alone. Lighting and isolation support a direct comparison with sonographic concepts like placental location, cord insertion site, and expected fetal posture without visual clutter. Small details count. Use this illustration in second-trimester embryology and obstetrics lectures, in atlases discussing fetoplacental anatomy, or in patient-facing materials that explain placenta and umbilical cord relationships alongside routine anatomy scans. It also suits perinatal pathology and radiology publications that need a neutral, isolated reference image at week 23. Anatomical accuracy verified by SciePro's Medical Advisory Board.
