Human Fetus at 20 Weeks in the Womb, Lateral View (Asian Skin)

Description

This close-up renders a fetus at approximately 20 weeks of gestation lying curled within the uterine cavity, seen in near-lateral profile. The rounded, hairless cranial vault dominates the frame, with the closed fused eyelids, low nasal bridge, short nose and softly formed lips clearly modelled; the auricle of the external ear is visible on the lateral surface of the head with its early helix and lobule. One flexed forearm and hand rise toward the face, individual fingers separated and nails forming, while the shoulder, upper torso and a flexed lower limb occupy the lower field. The umbilical cord passes obliquely across the forehead, its coiled umbilical vein and paired arteries visible through the translucent cord wall, and the warm red uterine wall closes the background. At 20 weeks the pregnancy has reached the midpoint of gestation and this is the standard timing of the second-trimester anomaly scan, when biometry, facial profile, orbits, ears, limbs and digits are systematically assessed. The lateral facial profile shown here corresponds to the sonographic mid-sagittal profile view used to evaluate the nasal bone, chin and forehead, while the free loop of cord across the head illustrates why nuchal or facial cord loops are commonly encountered on ultrasound. Hand-to-face contact at this stage reflects developing flexor tone and coordinated limb movement, and cord vessel number and coiling are routinely documented as part of the same examination. The image suits obstetric and midwifery teaching on second-trimester development, antenatal classes and patient-facing material explaining what the anomaly scan shows, and embryology or developmental anatomy chapters requiring a realistic in-utero figure. It also serves publishers, health communication agencies and prenatal ultrasound training resources that need a consistent 20-week reference alongside later gestational stages.
