This photo of an opened
oviduct with an
ectopic pregnancy features a spectacularly well preserved 10-millimeter five-week-old human
embryo. It is uncommon to see any embryo at all in an ectopic, and for one to be this well preserved (and undisturbed by the
prosector's knife) is quite unusual. Even an embryo this tiny shows very distinct
anatomic features, including
tail,
limb buds,
heart (which actually protrudes from the chest),
eye cups,
cornea/
lens,
brain, and prominent segmentation into
somites.
