Selaput Ekstra EmbryoSelaput ekstra embrio adalah lapisan pelindung bagi organ dalam yang dibatasinya. Amnion Vital functions of the membranes Keep embryo in fluid Gas exchange Removal or storage of waste materials NutritionYolksackAllantois Selaput Ekstra Embryo


Terdapat hanya pada reptilia, aves dan mamalia

MATERIAmnion Yolksack Allantois Chorion

Amnion thin

ectodermally-derived membrane enclosing embryo in fluid-filled sac For secretion and

absorption of amniotic fluid

MATERIAmnion Yolksack Allantois Chorion

Yolk sac

endodermal, involved with

nutrition of the embryo in largeyolked forms.

MATERIAmnion Yolksack Allantois Chorion


endodermal, originate from ventral surface of early hindgut; Act as reservoir for

storing or removing urinary wastes and mediate gas exchange between embryo and surrounding

MATERIAmnion Yolksack Allantois Chorion

Chorion outermost membrane; In species that

lay eggs, the principal function is the respiratory exchange of gases. In mammals, nutrition, excretion, filtration and synthesis (hormone)

MATERIFour Sets of Embryonic Membranes in Land Vertebrates Membranous folds formed by extension of

ectoderm and endoderm underlain with lateral plate mesoderm Somatopleure forms amnion and chorion Splanchnopleure allantois and yolk sac

MATERIExtraembryonic Membrane of the Chick Yolk Sac splanchnopleure grows over yolk surface; yolk as

temp. floor; then completely surround the yolk Subcephalic pocket - forms floor of foregut Subcaudal pocket hindgut Midgut Yolk duct opening of the midgut Yolk stalk wall of the duct Vitelline arc yolk circulatory arc Endoderm of yolk sac absorptive and synthetic Completely resorpted 6 days after hatching

MATERIAmnion and chorion Derived from extraembryonic somatopleure First indication appears about 30 hours of incubation Somatopleure is thrown into a head fold and tail fold

and lateral folds Continued growth of the amnion results in the meeting above the embryo, results to scar like thickening called amniotic raphe
