Human Fetus at 29 Weeks in the Womb (Asian Skin)

Description

The fetus lies curled in the amniotic cavity in a flexed attitude, with the head turned toward the viewer, the limbs drawn against the trunk and the knees held close to the abdomen. Surface detail characteristic of the third trimester is evident: scalp hair, a fully formed external ear with a defined helix and lobule, separated fingers and toes with visible nail beds, and subcutaneous fat that has begun to smooth the contours of the limbs and cheeks. The umbilical cord emerges from the abdominal wall and spirals across the trunk to the placenta, its paired umbilical arteries and single umbilical vein rendered as intertwined red and violet vessels. The discoid placenta is seen in profile against the uterine wall, its fetal surface carrying branching chorionic vessels that converge on the cord insertion. At 29 weeks the fetus is well into the third trimester, a period dominated by rapid brain growth, accumulation of white adipose tissue and continuing alveolar development with rising surfactant production. This gestational age sits at the centre of clinical discussions about preterm birth, antenatal corticosteroids and neonatal intensive care outcomes. The relationships shown here are also those assessed sonographically: cord coiling and vessel number, placental position and appearance, fetal lie and presentation, and biometry used to estimate fetal weight and detect growth restriction. The image suits obstetric and midwifery teaching, antenatal classes, and patient-facing material explaining fetal development week by week to expectant parents. It works as a figure in textbooks of embryology and perinatal medicine, in neonatology resources on prematurity, and in editorial or app content tracking pregnancy milestones, particularly where a series of gestational stages is presented side by side.
