Summary

Morphogenetic movements of the anterior intestinal port of in vitro growing chick embryos were recorded in stages 5–12 by means of microkinematography.

Anterior intestinal port moves between stages 7 and 12 by 1.02 mm caudally, while the cranial end of the head migrates by 0.45 mm cranially.

Rate of descensus, which is high during stages 7–9, decreases continually approaching 0 in stage 12.

The results are discussed in connection with the formation of intestinal port and of foregut.
