Fetus at Week 21 - Brown Skin

Description

Fetus at 21 weeks’ gestation is presented in utero with the placenta and umbilical cord included as a single anatomic unit against a black background. The fetal head sits superior to the thorax and abdomen, with the upper and lower limbs flexed in a typical second-trimester posture; the hands and feet are proportionally small relative to the cranium. Placental tissue occupies one side of the frame with the umbilical cord coursing from the fetal anterior abdominal wall at the umbilicus to its placental insertion, emphasizing the proximal to distal continuity of the fetoplacental circulation. Brown fetal skin tone is represented across the exposed integument, aiding inclusive teaching sets without obscuring surface landmarks. At 21 weeks, obstetric care often centers on the mid-trimester anatomic survey, when biometric parameters and external morphology are assessed alongside placental location and cord insertion. This illustration supports teaching the relationship between the umbilical cord and fetal abdominal wall, a practical reference when discussing omphalocele versus physiologic midgut herniation (which should have resolved by this stage), and when introducing abnormal placentation or velamentous insertion as contributors to fetal growth restriction. High contrast lighting against the dark field separates fetal contours from placental tissue so limb positioning, craniofacial profile, and the cord course remain readable without visual clutter. A single frame. No distractions. Obstetrics and embryology instructors can place this illustration in second-trimester development modules, prenatal counseling handouts, and textbook figures addressing placental anatomy and fetoplacental exchange. Maternal fetal medicine services and ultrasound education programs can also pair it with 20 to 22 week scan content to orient learners to expected external anatomy and the umbilical insertion site.
