Endoscopic image of the human foetus in vivo after 15 weeks, showing the external ear almost fully formed (the ear is viewed from behind, & the portion seen is the helix, the curved outer part of the ear) . 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).
