Human Fetus at 38 Weeks in the Womb (Asian Skin)

Description

A full-term fetus at approximately 38 weeks of gestation lies curled in the uterine cavity, filling nearly the whole frame against the deep red uterine wall. The head is turned so the face is seen in three-quarter profile, with dark scalp hair, fused-open lids now firmly closed, a well-formed auricle with defined helix and lobule, a rounded nasal tip and full lips. One hand rests against the cheek and mouth with individual fingers and fingernails distinguishable, the forearm crossing the chest, while the flexed thigh, knee and foot with separated toes occupy the upper field. The umbilical cord loops between the limbs, its spiralled vessels visible through the translucent Wharton's jelly. At 38 weeks the fetus is considered early term: subcutaneous fat has smoothed the skin and rounded the limbs, lanugo is largely shed, scalp hair is established and the flexed, adducted posture reflects the physiological flexion tone of a mature neonate within a uterus of limited residual volume. This stage is the reference point for assessing fetal growth on third-trimester ultrasound, for estimating amniotic fluid volume and for judging lie, presentation and cord position before labour. The visible cord looping among the limbs illustrates the anatomy underlying nuchal and body cord loops and the rationale for intrapartum fetal monitoring. The image supports obstetric and midwifery teaching on term fetal development and fetal positioning, antenatal class material and clinic posters explaining what the baby looks like in the final weeks, and publisher figures in embryology and obstetrics atlases. It also serves patient-facing apps, parenting resources and public-health communication on term birth timing, and pairs with the earlier second-trimester views in this series to show growth across gestation.
