Fetus at Week 25 - Brown Skin

Description

Fetus at 25 weeks’ gestation is presented in an alternative pose with the placenta and umbilical cord included in the same frame, allowing the fetal body to be read in relation to its extraembryonic support. Head and trunk proportions reflect late second-trimester growth, with the cranium still relatively large compared with the abdomen and limbs, and the flexed extremities positioned close to the torso. Placental tissue lies adjacent to the fetal surface, with the umbilical cord extending from the umbilicus toward the placental disc, consistent with the normal course of the umbilical vein and paired umbilical arteries within Wharton’s jelly. Brown fetal skin tone is depicted against a white background for isolation. Week 25 sits near the threshold of periviability, so this illustration pairs well with discussions of neonatal survival, respiratory distress syndrome, and the role of antenatal corticosteroids in accelerating surfactant production. Placenta and cord context also supports teaching on fetal oxygenation and nutrient delivery, and why placental insufficiency can present as fetal growth restriction or abnormal Doppler velocimetry in the umbilical artery. The fixed, uncluttered isolation makes external landmarks easy to reference, including the umbilical insertion site and overall limb posture. Scale matters here. Use this illustration in obstetrics and embryology lectures when contrasting second-trimester versus third-trimester morphology, in perinatology materials addressing viability counseling, or in patient-facing pregnancy education where inclusion of placenta and umbilical cord helps explain fetoplacental circulation without introducing imaging artifacts.
