PPT-Extra Embryonic Membranes:

Definition of Extra Embryonic Membrane The blastoderm in birds reptiles and mammals not only gives rise to embryo but also to certain structures that lie outside the embryo These extra embryonic structures are called Extra Embryonic Membrane. Objectives. Explain prenatal development from fertilization to birth. Understand different biological process’ in all phases of prenatal development. Define key vocabulary. Chart different phases in . Cleavage. Cleavage. . Fertilization takes place in the ampulla of the oviduct. Cleavage takes place as the zygote moves down the oviduct towards the uterus.

Nanofiltration. Reverse osmosis. Membrane fouling. Mineral scaling. Biofilm formation . Formation of the Digestive Cavity. At the Blastula stage, the embryo forms a fluid filled ball of cells. During Gastrulation, the blastula caves in on one end to form a Gastrula. The cavity formed by gastrulation will form a digestive cavity or digestive tract.. (Development of placenta). . .

During development of embryo the germ layer extends far from the embryonic area and peripheral part of the germ layer give rise to extra embryonic membrane. Vohra. vohra@ksu.edu.sa. OBJECTIVES.
