This is an illustration of a
24-hour chick embryo lying on top
of its yolk. The various
structures and layers present at
this time are color-coded. The
neural tube, derived from
ectoderm, is blue. The somites
and mesodermal layer from which they
are derived are red. The gut,
derived from endoderm, is yellow.
