Fetus at Week 21 - Brown Skin

Description

Fetus at 21 weeks’ gestation is shown in an alternative pose with the placenta and umbilical cord against a white background, allowing the fetal body contour to read without distraction. The head appears proportionally large relative to the trunk, with identifiable facial profile, flexed cervical posture, and developing external ear (auricle) lateral to the temporal region. Distally, the upper and lower limbs are formed with separated digits, and the umbilical cord courses from the anterior abdominal wall toward the placental disc, with fetal and placental surfaces clearly separated by the cord insertion. Brown fetal skin tone is presented consistently across the integument. Week 21 sits in the second trimester, when obstetric assessment focuses on fetal biometry and structural survey, so the relationship of the fetal trunk, limbs, and cord insertion helps learners connect external landmarks to sonographic planes used for head circumference, abdominal circumference, and femur length. Placental position and cord morphology matter in clinical documentation because abnormal cord insertion (marginal or velamentous) and placental complications (previa, abruption) change surveillance and delivery planning, and this single-frame anatomy supports that discussion without visual clutter. Subtle surface detail also supports embryology teaching on skin maturation and the progressive definition of the pinna, eyelids, and digits. A practical reference. Use this illustration in obstetrics and gynecology lectures, prenatal counseling materials, and medical publishing that needs a standardized second-trimester fetal development visual with placenta and umbilical cord included in the same frame. It also fits embryology modules and patient education handouts discussing gestational age milestones and placental anatomy. Anatomical accuracy verified by SciePro's Medical Advisory Board.
