Human Fetus at 22 Weeks in the Womb (Brown Skin)

Description

A fetus at approximately 22 weeks of gestation lies curled in the uterine cavity, seen in profile with the head filling the left of the frame and the flexed limbs gathered anteriorly. The cranial vault is large relative to the face, still smooth and hairless, with the fontanelles and sutures unossified beneath thin translucent skin. Facial detail includes fused, closed eyelids, a formed nose with patent nares, softly defined lips and a well-modelled external ear (auricle) set low on the side of the head. One hand rests near the mouth with individually separated fingers, while the opposite arm, thigh, lower leg and foot with distinct toes are folded into the characteristic fetal position. The umbilical cord passes across the upper field, its spiralled umbilical vessels visible through the covering of Wharton's jelly, against the soft red glow of the surrounding uterine wall. The second trimester at 22 weeks sits near the threshold of viability, making accurate depiction of external morphology at this age clinically relevant for counselling and for interpreting mid-trimester imaging. Structures shown here correspond to those assessed at the anomaly scan: cranial contour and biparietal diameter, orbits and profile, ear position, hand and foot morphology, and cord insertion with vessel count. Hand-to-mouth activity and limb flexion reflect the maturing neuromuscular coordination and early sucking reflexes typical of this period, while skin remains thin and covered by vernix and lanugo. The rendering suits obstetric and midwifery teaching, prenatal development chapters in embryology atlases, and antenatal patient education explaining what the fetus looks like at the halfway point of pregnancy. It also serves ultrasound training material as a photorealistic reference alongside sonographic images, and provides publishers, health campaigns and device companies with a consistent series figure for week-by-week gestational timelines.
