Sixteen-week-old foetus. Coloured ultrasound scan of a 16-week-old human foetus in side view. The head is in the upper right,with the face in profile towards centre. The torso is at lower centre,and a limb seen at left. At this age the foetus appears completely human. Fingers and toes will have formed and the skin will be 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 14 centimetres and the weight about 200 grams. Ultrasound scanning uses high-frequency sound waves to build images of structures inside the body. Scanning in pregnancy enables foetal development to be assessed | |
