Fetus at Week 21 - Brown Skin

Description

Fetus at 21 weeks’ gestation appears with the placenta and umbilical cord in a single, isolated composition against a black background. Within the frame, the placental disc lies adjacent to the fetal trunk, while the umbilical cord courses from the placental surface to the fetal umbilicus on the anterior abdominal wall, emphasizing the fetoplacental connection. Cranially, the head remains proportionally large relative to the thorax and abdomen, with formed external ears and a defined facial profile; caudally, the lower limbs extend inferiorly with separated toes and flexed joints. Brown fetal skin tone is presented consistently across the integument. Week 21 sits squarely in the second trimester, the same window as the standard mid-trimester anatomy survey, so the relationship between fetus, placenta, and cord insertion becomes more than academic. One static frame that includes the umbilical insertion helps you teach the difference between normal central insertion and clinically relevant variants such as marginal insertion, velamentous insertion, or a single umbilical artery, each associated with fetal growth restriction and increased surveillance. Surface detail also supports discussion of expected developmental findings at this age, including eyelid fusion status, early lanugo, and proportion changes that track with biometric measurements used in prenatal care. Use this illustration in obstetrics and gynecology lectures, embryology blocks covering placentation and fetoplacental circulation, or patient-facing materials explaining the 20 to 22 week anatomy scan and placental assessment. It also suits perinatal pathology or maternal-fetal medicine publications that need an accurate second-trimester fetal reference with inclusive brown skin representation.
