Human Fetus in the Womb at 40 Weeks (Asian Skin)

Description

A fetus at 40 weeks of gestation lies curled in the uterine cavity, shown from a posterolateral vantage that reveals the occiput and rounded head with a full covering of scalp hair, the folded auricle of the ear, and the face turned toward the flexed upper limb. The trunk is in physiological flexion: knees drawn up toward the abdomen, plantar surfaces of the feet with well-formed toes crossing in front of the thighs, and one hand raised near the chest with individually separated fingers. The umbilicus is visible on the abdominal wall, and the umbilical cord ascends from it in a spiral, its paired umbilical arteries and single umbilical vein suggested by the twisted red and violet cording. Behind the fetus the placental disc is applied to the richly vascularised endometrial surface, and the smooth uterine wall closes the space around the crowded fetal body. At term the fetus has accumulated generous subcutaneous fat, giving the smooth rounded body contours and skin creases seen here, and the vertex-down flexed attitude illustrated is the presentation that most favours normal vaginal delivery. This depiction is directly relevant to teaching fetal lie, presentation and attitude, to discussion of engagement and the mechanism of labour, and to counselling on cord length, coiling and nuchal cord risk. The placental and uterine relationships shown also support explanation of placental gas and nutrient exchange, oligohydramnios and reduced fetal movement at term, and the anatomy encountered at caesarean section. Suitable for obstetric and midwifery teaching collections, embryology and human development atlases, antenatal class and patient education handouts, and editorial or publication figures on late pregnancy and birth preparation. As part of a graded series following the same Asian fetal subject from week 20 to term, it allows educators to compare growth in body proportion, subcutaneous tissue and posture across gestation.
