Characteristic Features of Avian Gastrulation

  • Creation of hypoblast and its important role in formation of the axis and orientation of embryo.
  • Existence of the cells of all the three germinal areas in the epiblast.
  • Creation of the primitive streak and its regression in law stages of gastrulation.
  • Nonexistence of archenteron formation.
  • Gastrula cell movements include poly invagination, involution, convergence, divergence and epiboly.
  • Cephalocaudal separation of axial structures and growth of the embryo during gastrulation.
