Selaput ekstra embrio adalah lapisan pelindung bagi organ dalam yang dibatasinya.

Terdapat hanya pada reptilia, aves dan mamalia

SELAPUT EKSTRA EMBRIO AVES

Amnion – thin ectodermally-derived membrane enclosing embryo in fluid-filled sacFor secretion and

absorption of amniotic fluid

Allantois ChorionAmnion Yolksack MATERI

SELAPUT EKSTRA EMBRIO AVES

Yolk sac – endodermal, involved

with nutrition of the embryo in large–yolked forms.

Allantois ChorionAmnion Yolksack MATERI

Page 8: Presentation 1

Allantois – 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

SELAPUT EKSTRA EMBRIO AVES

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)

Four Sets of Embryonic Membranes in Land VertebratesMembranous folds formed by extension of

ectoderm and endoderm underlain with lateral plate mesoderm

Somatopleure – forms amnion and chorionSplanchnopleure – allantois and yolk sac

MATERI

Page 11: Presentation 1

splanchnopleure grows over yolk surface; yolk as temp. floor; then completely surround the yolk

Subcephalic pocket - forms floor of foregutSubcaudal pocket – hindgut MidgutYolk duct – opening of the midgutYolk stalk – wall of the ductVitelline arc – yolk circulatory arcEndoderm of yolk sac – absorptive and

synthetic Completely resorpted 6 days after hatching

Extraembryonic Membrane of the Chick – Yolk Sac

Amnion and chorionDerived from extraembryonic somatopleureFirst indication appears about 30 hours of

incubationSomatopleure is thrown into a head fold and

tail fold and lateral foldsContinued growth of the amnion results in

the meeting above the embryo, results to scar –like thickening called amniotic raphe
