Endoscopic image of the human foetus in vivo, after 7 weeks, showing the developing outer ear placed low on the neck (centre-top of image circle). The endoscope, a series of lenses and a fibre-optic light source, is inserted through the cervix and manipulated until a "window" into the amniotic sac is found (ie an area where the wall is thinner).
