Sixteen-week-old foetus. Ultrasound scan of a 16- week-old human foetus in side view. The head is in the upper right. At this age the foetus appears completely human. Fingers and toes have formed and the skin is covered with a fine hair (lanugo) while eyebrows and hair on the head develop. The crown-rump length (sitting height) at 16 weeks is about 14cm and the weight about 200g. Ultrasound scanning uses high-frequency sound waves to build images of structures inside the body | |
