Human Fetus at Gestational Week 27 Without the Placenta

Description

Rendered at approximately 27 weeks’ gestation, the conceptus appears in a flexed, fetal position within the uterine cavity, with the head relatively large and the spine forming a gentle C shaped curve along the posterior aspect. Facial anatomy is sufficiently developed to appreciate the eyelids (eyes closed), external ear (auricula) contours, and early scalp hair, while the upper limbs rest anteriorly with the wrists flexed and the digits clearly separated. Lower limbs lie inferiorly with the hips and knees flexed, bringing the feet toward the trunk. A prominent umbilical cord courses from the fetal umbilicus toward the placental site, although the placenta itself is intentionally omitted to keep attention on fetal morphology. At 27 weeks, many teaching and clinical questions shift from organogenesis to growth, viability, and the consequences of uteroplacental disease, so isolating the fetus while retaining the umbilical cord provides a clean way to discuss fetal circulation without the visual dominance of placental tissue. This gestational window also aligns with practical bedside counseling around preterm labor, antenatal corticosteroids, and expected neonatal outcomes, where clinicians and educators often need a realistic reference for body proportions, flexion posture, and surface maturation. The cord’s visibility supports discussion of cord accidents, true knots, and nuchal cord, which are frequently described but rarely visualized in a way that reads clearly. Use this artwork in embryology and obstetrics teaching blocks to anchor week-by-week development, in patient education materials on second to third trimester fetal growth, or in perinatology publications describing preterm viability and umbilical cord related complications. It also fits NICU and MFM slide decks when explaining why fetal posture and cord integrity matter in late gestation. Anatomical accuracy verified by SciePro's Medical Advisory Board.
