The human foetus after 10 weeks,showing the head. After 8 weeks the embryo has become a foetus (ie it vaguely resembles the ultimate adult). Development during the 3rd month is characterised by rapid growth & increase in weight. The facial features have changed; eyes have migrated from the sides of the head (dark spot at bottom of image is the retina of one). The forehead is high & bulging,with the joins in the plates of bone which comprise the skull visible. Internal sexual differentiation takes place at this time,though external differences are not yet obvious | |
