Extraembryonic Membrane Development definitions Flashcards

Specialized structures outside the embryo aiding in protection, nutrient exchange, and waste removal.

Forms from primitive gut cells, provides early nutrition, and contributes to digestive tract, blood, and germ cell formation.

Transparent membrane creating the amniotic cavity, secretes fluid for protection and muscle development.

Fluid derived from maternal blood and fetal urine, cushions fetus, maintains temperature, and supports muscle growth.

Embryonic tissue forming part of the umbilical cord and urinary bladder, aiding in vasculature development.

Early embryonic structure from which the yolk sac forms, contributing to digestive tract development.

The embryo and its associated membranes during early development stages.

Structure formed partly by the allantois, connecting the fetus to the placenta for nutrient exchange.

Early reproductive cells produced by the yolk sac, contributing to gamete formation.

Early stage of embryonic development consisting of two layers, forming the basis for further differentiation.
