Endoscopic image of the human foetus in vivo,after 9 weeks,showing both hands held in front of the face: the nail beds of the fingers,the bone- forming cartilage of the hand,and the blood vessels of the hand (visible through translucent skin) are all evident. The endoscope,a series of lenses and a fibre-optic light guide,is inserted through the cervix (the neck of the womb) and manipulated until a "window" into the amniotic sac is found (ie an area where the wall is thinner) | |
